Scan Ladder Vs. UltraFitScan: Dental Photogrammetry Comparison
Introduction to Dental Photogrammetry
Achieving passive fit in full-arch implant rehabilitation remains one of the greatest challenges in digital dentistry. While intraoral scanners revolutionized single-unit workflows, edentulous arches present a notorious obstacle: a lack of distinct anatomical landmarks causes stitching errors, cumulative distortion, and costly implant angle discrepancies over long scan paths. This is where dental photogrammetry excels.
Whether you are placing All-on-X cases or delivering immediate-load prostheses, precise implant multi-unit positioning is non-negotiable. Modern full-arch digital workflows offer powerful solutions to bridge this accuracy gap, ranging from dedicated dental photogrammetry systems to specialized scanbody innovations like UltraFitScan and Scan Ladder.
Key Digital Full-Arch Technologies:
IOS-Based Dental Photogrammetry Systems: Solutions that utilize specialized coded scanbody arrays—such as Scan Ladder, UltraFitScan, or Shining 3D’s Intraoral Photogrammetry (IPG) system (featured in the Aoralscan Elite)—to eliminate edentulous stitching drift directly within intraoral scanning workflows.
Dedicated Dental Photogrammetry Cameras: Handheld or extraoral multi-camera stereophotogrammetry systems—such as the Runyes G6 iGraphy, PIC System (PIC Dental), and ICam 4D (Imetric 4D)—designed exclusively to capture precise 3D spatial implant positions and vector angulations without relying on intraoral scan paths.
Comparing dedicated photogrammetry, optimized intraoral scanning, UltraFitScan, and Scan Ladder systems helps identify the most reliable, accurate full-arch digital workflow for your practice.
The Rise of Horizontal Scan Bodies in Full-Arch Implant Alignment
The evolution of full-arch implant scanning has increasingly focused on creating artificial reference points that help an intraoral scanner maintain positional information across an edentulous arch.
Traditional scanbody workflows can become challenging when implants are widely separated. The scanner must repeatedly stitch images together despite the absence of strong natural landmarks. This is one reason specialized scanbody geometries and cross-arch reference systems have become increasingly important.
Rather than relying exclusively on the patient’s anatomy, these systems introduce recognizable geometric structures into the scan. Scan Ladder, for example, uses individually shaped scanbodies combined with a patented random surface and a Common Matching Cylinder. Its latest system also allows a central-focus scanning strategy, in which the clinician can begin with scanbodies positioned close together before extending the scan toward the distal areas.
UltraFitScan approaches the same fundamental problem differently. Its brochure describes an encoded scanbody system designed specifically for edentulous implant restorations, combined with HS caps that provide gingival reference information.
The result is an emerging category between conventional intraoral scanning and dedicated dental photogrammetry: specialized implant-position acquisition systems that use an IOS as the imaging device.
What is Scan Ladder?
Scan Ladder is an advanced full-arch implant scanning system designed to improve the accuracy and reliability of intraoral scanning in edentulous and implant-supported restorations. It is particularly relevant to All-on-4, All-on-6 and All-on-X implant workflows, where accurately capturing the three-dimensional position of multiple implants is critical for producing a precise, passive-fitting prosthesis.
Unlike conventional implant scanbody workflows, Scan Ladder uses specially engineered individual scanbody geometries, together with its patented random-surface technology and Common Matching Cylinder, to provide additional reference information during intraoral scanning. This approach is designed to address one of the major challenges of full-arch digital impressions: maintaining accurate spatial relationships when scanning across long, edentulous arches with limited natural anatomical reference points.
Scan Ladder is an IOS-based solution rather than a dedicated photogrammetry camera, allowing dental professionals to integrate it into an existing digital workflow. It is designed to work with multiple intraoral scanner and CAD ecosystems, making it an attractive option for implantologists, prosthodontists and dental laboratories seeking a more predictable digital full-arch implant workflow without investing in a dedicated photogrammetry camera.

Scan Ladder Kit & Components
The Scan Ladder ecosystem is built around the Scan Ladder Titanium Direct as its main kit for full-arch implant scanning. The Titanium Direct kit uses six individually shaped titanium scanbodies, each designed to provide a recognizable reference during intraoral scanning. The Scan Ladder system can be expanded with several complementary options depending on the clinical and laboratory workflow. TissueSync can be added to improve soft-tissue matching, while the Indirect Kit is a single-use scanning aid designed to lock onto and assist with scanning third-party scanbodies. The GuideLockâ„¢ System uses fiduciary markers to further support the Scan Ladder workflow, while LabSync provides dedicated laboratory scanbody components for transferring the digital workflow into the dental laboratory. These options allow clinicians and laboratories to configure Scan Ladder according to their specific full-arch implant and restorative requirements. The manufacturer recommends purchasing the appropriate Scan Ladder Guide together with the selected kit at checkout, as the guide is required for the corresponding workflow.
Scan Ladder Options
- Scan Ladder Titanium Direct — the main reusable titanium full-arch scanning kit.
- TissueSync Scanbody Set — designed to improve matching between implant-position data and soft-tissue anatomy.
- Scan Ladder INDIRECT Kit — a single-use scanning device that locks onto and assists in scanning third-party scanbodies.
- GuideLock™ System — fiduciary marker kits designed to support the full Scan Ladder workflow.
- LabSync — laboratory scanbody components designed to extend the Scan Ladder workflow into the dental laboratory.
Scan Ladder Workflow
The Scan Ladder Titanium Direct system is designed to attach directly to multi-unit abutments. Its current kit contains six individually shaped matt-titanium scanbodies and six screws. Each scanbody has a different geometry, allowing the scanner or CAD software to distinguish the individual components and helping reduce confusion between identical scanbody shapes.
The workflow is fundamentally IOS-based.
First, the Scan Ladder components are connected to the multi-unit abutments. The clinician then performs the intraoral scan using a compatible intraoral scanner. Scan Ladder’s current design incorporates a patented random surface intended to improve the ability of the scanner to connect successive scan frames.
The system also incorporates a Common Matching Cylinder. Two of the newer scanbody shapes are elongated, allowing clinicians to position the scanbodies centrally and begin the scan around the middle of the arch before extending toward the posterior regions.
This central-focus approach is particularly relevant to full-arch implant cases because it attempts to minimize the distance between early scan frames and create a stronger reference relationship before scanning the remainder of the arch.
Scan Ladder describes the Titanium Direct system as an open workflow that can be used with different scanners and is not tied to a particular laboratory. The system also supports current CAD libraries, including Exocad and 3Shape workflows.
For clinicians performing immediate-load full-arch restorations, this can create a highly digital workflow from implant scanning through CAD design.
Scan Ladder Pros
Open IOS Workflow
One of Scan Ladder’s strongest advantages is its open approach. Rather than requiring a proprietary intraoral scanner, the system is designed to work with different IOS platforms.
This is particularly useful for dental practices that already own an IOS and want to improve full-arch implant scanning without purchasing an entirely new scanning platform.
Individual Scanbody Geometry
Each Titanium Direct scanbody has an individual shape. This is an important design characteristic because the software can distinguish different scanbodies rather than relying on multiple identical components.
Random Surface Technology
Scan Ladder uses a patented random surface designed to provide additional topographical information for the scanner. According to the manufacturer, this helps scan frames connect more reliably in edentulous full-arch situations.
Central-Focus Scanning
The central-focus workflow is another significant feature. By positioning suitable scanbodies toward the centre of the arch, the clinician can begin scanning from a compact area before extending the scan across the arch.
Clinical Evidence
Scan Ladder has an important advantage in terms of published evidence. The manufacturer reports an in-vivo peer-reviewed study comparing Scan Ladder-assisted scanning with the accuracy of intraoral and extraoral photogrammetry systems.
For clinicians evaluating new digital dentistry technologies, independent clinical evidence is an important consideration alongside manufacturer specifications.
Scan Ladder Cons
Despite its advantages, Scan Ladder is not necessarily the ideal solution for every clinician.
First, it remains fundamentally an IOS-based system. The accuracy of the final result therefore depends on the scanner, scanning technique, software workflow and clinical conditions. It is not a dedicated photogrammetry camera.
Second, the standard Titanium Direct kit focuses primarily on implant-position acquisition. Scan Ladder offers TissueSync as an additional solution for improving soft-tissue matching, meaning clinicians requiring a comprehensive implant-plus-soft-tissue workflow may need additional components.
Finally, clinicians must ensure compatibility between their implant/MUA connection, scanbody configuration and CAD library before beginning a case.
What is UltraFitScan?
UltraFitScan is an AI-powered full-arch reconstruction data acquisition system developed specifically for edentulous implant restorations and immediate full-arch workflows. Rather than functioning as a dedicated photogrammetry camera, UltraFitScan combines an intraoral scanner, encoded implant scanbodies, HS gingival scanning caps and dedicated software to acquire and match implant-position and soft-tissue data.
The UltraFitScan workflow begins by attaching the appropriate scanbodies to the multi-unit abutments and scanning them with an intraoral scanner. The scanbodies are then replaced with HS caps, which provide gingival soft-tissue reference points. The implant and gingival datasets are subsequently imported into the UltraFitScan software platform for data conversion and matching before the final file is exported to dental CAD software for restoration design.
According to the March 2026 manufacturer brochure, UltraFitScan’s scanning bodies are compatible with any intraoral scanner, while the UF-A and UF-B kits are claimed to cover more than 95% of implant systems. The manufacturer also states a scan-data error of ≤0.01 mm, although this should be regarded as a manufacturer specification rather than independently validated clinical accuracy.
For implantologists and prosthodontists, UltraFitScan represents an emerging approach to digital full-arch implant scanning, combining implant-position acquisition, gingival reference scanning and AI-assisted data matching within a single workflow.
UltraFitScan Kit & Components
UltraFitScan is available in two dedicated kit configurations — UF-A and UF-B — giving dental professionals the flexibility to select the appropriate system according to the multi-unit abutment connection used in the full-arch case. Both kits include 12 UltraFitScan scanbodies, available in S, M and L sizes, with four scanbodies of each size. The kits also include the corresponding HS gingival caps, fixation screws and screwdriver/hex components required for the scanning workflow. The key difference between the two configurations is the supported screw connection: UF-A covers M1.4 and M1.6, while UF-B covers M1.8 and M2.0.
UF-A — M1.4 / M1.6
The UF-A kit is designed for multi-unit abutments using M1.4 or M1.6 screw connections. It includes four S-size, four M-size and four L-size UltraFitScan scanbodies, providing different scanbody dimensions for varying implant positions and anatomical conditions. The kit also contains the corresponding M1.4 and M1.6 HS caps and screws, together with the required screwdriver/hex components.
UF-B — M1.8 / M2.0
The UF-B kit provides the same S/M/L scanbody configuration but is designed for M1.8 and M2.0 screw connections. It includes four scanbodies in each size, along with the corresponding HS caps and screws for the supported connections. This gives clinicians an alternative configuration when treating implant systems using larger MUA screw dimensions.
Multiple Scanbody Sizes for Clinical Flexibility
The availability of S, M and L UltraFitScan scanbodies is intended to accommodate different implant positions and anatomical structures. The manufacturer specifically highlights the multiple-size design as a way of providing greater clinical flexibility during full-arch implant scanning.
Both UF-A and UF-B are part of the same UltraFitScan ecosystem, and the manufacturer states that the two configurations together are compatible with more than 95% of implant systems on the market. The brochure provides an extensive list of compatible systems and MUA configurations, including Nobel, Straumann, Neodent, Osstem, Dentium, Megagen, MIS, Camlog, Zimmer, Alpha-Bio and others.
UltraFitScan Workflow
UltraFitScan takes a different approach to full-arch implant scanning.
According to the March 2026 UltraFitScan brochure, the system combines encoded scanbody technology with HS cap technology and is specifically designed for immediate edentulous implant restorations.
The workflow consists of four principal stages:
1. Intraoral implant scanning: The UltraFit scanbodies are installed onto the multi-unit abutments and scanned using an intraoral scanner.
2. Gingival scanning: The UltraFit scanbodies are replaced with suitable HS caps, which are then scanned to capture gingival soft-tissue reference points.
3. Data matching: The implant and gingival datasets are imported into the UltraFit software platform, where the data is converted and matched.
4. Restoration design: The resulting scan file can then be exported into dental CAD software for restoration design.
This is one of UltraFitScan‘s most interesting characteristics: the manufacturer presents it not simply as a set of scanbodies, but as a Full Arch Reconstruction Data Acquisition System.
AI-Powered Alignment Without Manual Stitching
One of the most significant advantages of UltraFitScan is its dedicated software-based alignment workflow. Instead of relying entirely on the conventional stitching process of an intraoral scanner across a long, edentulous arch, UltraFitScan uses advanced AI alignment algorithms to match the captured implant data.
This is particularly valuable in full-arch implant cases, where the lack of anatomical landmarks can make conventional IOS stitching more challenging and may introduce cumulative positional errors. UltraFitScan is designed to address this problem by using the scanbody data as dedicated reference information and performing automated data matching through its software platform. The manufacturer describes the system as using AI-powered scanning technology to precisely determine implant placement.
Free AI-Automated Alignment Software
UltraFitScan goes beyond simply providing specialized scanbodies. The system includes a dedicated AI-powered software platform for importing, converting and matching the acquired scan data before exporting the final file to dental CAD software.
This automated approach can significantly simplify the full-arch workflow by reducing the need for manual alignment and positioning of implant data. For implantologists and prosthodontists, this means a more streamlined digital workflow from implant scanning → AI alignment → CAD design.
Designed to Reduce Full-Arch Stitching Errors
Full-arch edentulous scanning presents a fundamental challenge: there are relatively few natural anatomical reference points for an IOS to use when stitching multiple frames together. UltraFitScan was specifically developed to address this limitation. The manufacturer identifies distorted or inaccurate image stitching as one of the principal problems encountered during conventional edentulous scanning.
By using dedicated scanbody markers and AI-based data matching, UltraFitScan provides the software with defined implant-position references rather than depending exclusively on the patient’s soft-tissue anatomy.
The practical benefit is a workflow designed to minimize the cumulative stitching errors that can occur when scanning across a completely edentulous arch.
Compatible With Nearly Any Intraoral Scanner
Another major advantage is hardware flexibility. UltraFitScan states that its scanbody is compatible with any intraoral scanner, allowing dental professionals to use their existing IOS rather than purchasing a dedicated scanner specifically for the system.
This makes UltraFitScan particularly attractive for practices that already use scanners from manufacturers such as Medit, Shining 3D, 3Shape, Dentsply Sirona, iTero, Runyes and other major IOS brands, provided the specific clinical workflow and software export requirements are supported.
More Than 95% Implant-System Compatibility
UltraFitScan is designed to provide broad implant compatibility. The manufacturer states that the UF-A and UF-B kits cover more than 95% of implant systems on the market.
The March 2026 brochure specifically lists compatibility with numerous systems, including Nobel, Straumann, Neodent, Osstem, Dentium, Megagen, MIS, Camlog, Zimmer, Alpha-Bio, Adin, Dentis and others.
For practices treating patients with different implant systems, this broad compatibility can eliminate the need to maintain multiple completely different digital acquisition workflows.
Integrated Implant and Gingival Scanning
UltraFitScan is not limited to implant-position acquisition. Its HS caps enable the clinician to capture gingival soft-tissue reference points after scanning the implant scanbodies.
The workflow therefore combines:
Implant position data + gingival anatomy → AI-assisted data matching → CAD-ready digital file
This can be particularly useful for immediate full-arch implant restorations, where accurate implant positioning needs to be combined with the patient’s gingival anatomy for prosthetic design.
Reduced Scanning Area and Faster Data Acquisition
UltraFitScan also aims to reduce the amount of intraoral scanning required. The manufacturer states that only the markers need to be scanned, reducing the scanning area and potentially shortening acquisition time.
For a clinician performing multiple full-arch implant cases, reducing the amount of scanning required can translate into a more efficient chairside workflow and less time spent acquiring digital impressions.
Precision Titanium Scanbodies
UltraFitScan scanbodies are manufactured from TC4 ELI titanium, using integrated forming and high-precision machining. The manufacturer states that component manufacturing tolerances are within 0.005 mm (5 µm).
The manufacturer also states that UltraFitScan can capture scan data with an error of ≤0.01 mm (≤10 µm).
These figures should be presented as manufacturer-stated specifications, rather than independent clinical validation.
A Complete Digital Full-Arch Acquisition Workflow
Perhaps the biggest advantage of UltraFitScan is that it combines several technologies into one workflow rather than simply providing another set of implant scanbodies.
The complete process is:
UltraFitScan scanbodies → IOS acquisition → AI-powered alignment and data matching → HS cap gingival scan → CAD-ready output
The manufacturer explicitly describes the output file as being suitable for import into any dental CAD software for final restoration design.
For modern implantologists, prosthodontists and digital dental laboratories, this creates a compelling alternative to conventional full-arch IOS stitching and a potentially cost-effective alternative to purchasing a dedicated dental photogrammetry camera.
UltraFitScan Cons
UltraFitScan is an impressive new technology that was just launched in June 2026, so clinicians should consider several factors before adopting it.
A Newly Launched Technology
One of the main considerations is that UltraFitScan is a newly launched product. As a result, it does not yet have the same volume of long-term clinical experience or independently published research as more established full-arch implant scanning technologies such as Scan Ladder.
This does not necessarily indicate a limitation in the technology itself. In fact, the development approach suggests the opposite. The manufacturer has specifically invested approximately USD $290,000 in developing the dedicated UltraFitScan software, which is purpose-built for full-arch implant alignment rather than being a generic scanning or CAD application.
This is significant because the manufacturer has focused the software development specifically on one of the most challenging problems in digital implant dentistry: accurately determining and aligning multiple implant positions across a completely edentulous arch.
Independent Clinical Evidence Is Still Developing
UltraFitScan states a scan-data error of ≤0.01 mm (≤10 µm). However, this should currently be regarded as a manufacturer-stated specification, rather than an independently validated clinical accuracy figure.
Because UltraFitScan is new, clinicians should distinguish between the impressive technical specifications of the system and the amount of independent, peer-reviewed clinical evidence currently available.
That said, the substantial investment in dedicated alignment software demonstrates that the manufacturer has taken the accuracy challenge seriously. Rather than simply producing another set of implant scanbodies, Chirimen has developed a dedicated AI-powered alignment platform specifically for full-arch implant positioning. The brochure describes the software workflow as importing, converting and matching the acquired datasets before producing a file suitable for dental CAD software.
A Serious Attempt to Solve a Difficult Clinical Problem
Ultimately, the fact that UltraFitScan is new should not overshadow what makes the technology interesting.
Full-arch implant alignment is one of the most technically demanding applications of intraoral scanning. The absence of anatomical landmarks, long scanning paths and the potential accumulation of stitching errors can make accurate implant-position acquisition challenging. UltraFitScan was specifically developed around these problems.
The manufacturer’s reported USD $290,000 investment in dedicated software development and the decision to build a software platform specifically around full-arch implant alignment demonstrate a substantial commitment to addressing this challenge.
Therefore, rather than viewing UltraFitScan’s newness simply as a disadvantage, it may be more appropriate to see it as an emerging technology backed by a significant development effort, with clinical adoption and independent validation expected to provide a clearer picture of its long-term performance.
For dental professionals considering UltraFitScan today, the sensible approach is to recognize both sides: it is a new system with limited independent clinical evidence, but it has been purposefully engineered around one of the most frustrating accuracy challenges in full-arch digital implant dentistry.

UltraFitScan vs Scan Ladder: Which Should You Choose?
There is no universal winner.
For clinicians who prioritize independent clinical evidence, an open IOS workflow and a highly developed full-arch scanning methodology, Scan Ladder is an attractive option.
For clinicians who prioritize AI-assisted data matching, encoded scanbodies and integrated gingival-reference acquisition, UltraFitScan offers a compelling alternative.
The two technologies should therefore be viewed as competing approaches to the same fundamental challenge: obtaining accurate implant-position data from edentulous full-arch cases without relying entirely on conventional impression techniques.
For implantologists and prosthodontists, the decision should ultimately consider implant-system compatibility, existing IOS equipment, CAD workflow, soft-tissue requirements, clinical evidence, training and total acquisition cost.
A Glimpse at Dental Photogrammetry Cameras
Specialized dental photogrammetry cameras take a different approach.
Instead of asking an intraoral scanner to reconstruct a long edentulous surface, a dedicated photogrammetry system captures the spatial relationship between specialized implant markers using multiple photographic measurements.
This can provide an extremely efficient method of acquiring implant positions for full-arch implant restorations.
A dedicated photogrammetry camera can therefore complement — rather than replace — an intraoral scanner. The photogrammetry system captures the highly precise implant-position dataset, while the IOS can subsequently capture the gingiva, teeth, soft tissue and prosthetic anatomy.
This combination can be particularly powerful for demanding All-on-4, All-on-6 and All-on-X workflows.
Runyes iGrapher G6: A Dedicated Dental Photogrammetry Solution
For dental professionals looking to move beyond IOS-assisted full-arch implant scanning, the Runyes iGrapher G6 is a dedicated dental photogrammetry camera worth considering.
Runyes classifies the iGrapher G6 specifically under its Photogrammetry Camera category.
According to Runyes, the iGrapher G6 provides:
- 20–30 μm position measurement accuracy
- Measurement of 2–8 points
- 90 × 90 × 50 mm measuring space
- 260 mm measuring distance
- Approximately 20 seconds for a half-arch impression
- 1.3 kg weight excluding the bracket
- 2500 mAh battery
- 15 V / 1.5 A input voltage.
For a dental practice performing full-arch implant rehabilitation, the attraction is straightforward: instead of relying solely on the stitching capabilities of an IOS across a feature-poor edentulous arch, the iGrapher G6 is designed specifically to acquire implant-position information through photogrammetric measurement.
Why Consider Photogrammetry?
For demanding full-arch cases, implant position is not simply another part of the digital impression. It is the fundamental spatial reference on which the passive fit and accuracy of the definitive prosthesis depend.
That makes the choice between an enhanced IOS workflow such as Scan Ladder or UltraFitScan and a dedicated photogrammetry camera such as the Runyes iGrapher G6 an important clinical and technological decision.
Scan Ladder and UltraFitScan represent the growing generation of IOS-assisted full-arch acquisition technologies. Dedicated photogrammetry represents the alternative approach: use a purpose-built measurement system for implant positioning and an IOS for the surrounding oral anatomy.
For practices performing a high volume of All-on-4, All-on-6 and All-on-X cases, understanding both approaches allows clinicians to select the workflow that best matches their clinical protocols, equipment and restorative ecosystem.
The future of full-arch implant dentistry is increasingly digital — and accurate implant-position acquisition is at the centre of that transformation.
For dental surgeons, implantologists and prosthodontists evaluating the latest 3D dental technologies, comparing systems such as Scan Ladder, UltraFitScan and Runyes iGrapher G6 is therefore not simply a comparison of products. It is a comparison of three different approaches to solving one of the most important challenges in digital full-arch dentistry: capturing implant position accurately, efficiently and predictably.

IOS-Based Dental Photogrammetry Systems: Solutions that utilize specialized coded scanbody arrays—such as Scan Ladder, UltraFitScan, or Shining 3D’s Intraoral Photogrammetry (IPG) system (featured in the Aoralscan Elite)—to eliminate edentulous stitching drift directly within intraoral scanning workflows.
Dedicated Dental Photogrammetry Cameras: Handheld or extraoral multi-camera stereophotogrammetry systems—such as the Runyes G6 iGraphy, PIC System (PIC Dental), and ICam 4D (Imetric 4D)—designed exclusively to capture precise 3D spatial implant positions and vector angulations without relying on intraoral scan paths.
Comparing dedicated photogrammetry, optimized intraoral scanning, UltraFitScan, and Scan Ladder systems helps identify the most reliable, accurate full-arch digital workflow for your practice.
The Rise of Horizontal Scan Bodies in Full-Arch Implant Alignment
The evolution of full-arch implant scanning has increasingly focused on creating artificial reference points that help an intraoral scanner maintain positional information across an edentulous arch.
Traditional scanbody workflows can become challenging when implants are widely separated. The scanner must repeatedly stitch images together despite the absence of strong natural landmarks. This is one reason specialized scanbody geometries and cross-arch reference systems have become increasingly important.
Rather than relying exclusively on the patient’s anatomy, these systems introduce recognizable geometric structures into the scan. Scan Ladder, for example, uses individually shaped scanbodies combined with a patented random surface and a Common Matching Cylinder. Its latest system also allows a central-focus scanning strategy, in which the clinician can begin with scanbodies positioned close together before extending the scan toward the distal areas.
UltraFitScan approaches the same fundamental problem differently. Its brochure describes an encoded scanbody system designed specifically for edentulous implant restorations, combined with HS caps that provide gingival reference information.
The result is an emerging category between conventional intraoral scanning and dedicated dental photogrammetry: specialized implant-position acquisition systems that use an IOS as the imaging device.
What is Scan Ladder?
Scan Ladder is an advanced full-arch implant scanning system designed to improve the accuracy and reliability of intraoral scanning in edentulous and implant-supported restorations. It is particularly relevant to All-on-4, All-on-6 and All-on-X implant workflows, where accurately capturing the three-dimensional position of multiple implants is critical for producing a precise, passive-fitting prosthesis.
Unlike conventional implant scanbody workflows, Scan Ladder uses specially engineered individual scanbody geometries, together with its patented random-surface technology and Common Matching Cylinder, to provide additional reference information during intraoral scanning. This approach is designed to address one of the major challenges of full-arch digital impressions: maintaining accurate spatial relationships when scanning across long, edentulous arches with limited natural anatomical reference points.
Scan Ladder is an IOS-based solution rather than a dedicated photogrammetry camera, allowing dental professionals to integrate it into an existing digital workflow. It is designed to work with multiple intraoral scanner and CAD ecosystems, making it an attractive option for implantologists, prosthodontists and dental laboratories seeking a more predictable digital full-arch implant workflow without investing in a dedicated photogrammetry camera.

Scan Ladder Kit & Components
The Scan Ladder ecosystem is built around the Scan Ladder Titanium Direct as its main kit for full-arch implant scanning. The Titanium Direct kit uses six individually shaped titanium scanbodies, each designed to provide a recognizable reference during intraoral scanning. The Scan Ladder system can be expanded with several complementary options depending on the clinical and laboratory workflow. TissueSync can be added to improve soft-tissue matching, while the Indirect Kit is a single-use scanning aid designed to lock onto and assist with scanning third-party scanbodies. The GuideLockâ„¢ System uses fiduciary markers to further support the Scan Ladder workflow, while LabSync provides dedicated laboratory scanbody components for transferring the digital workflow into the dental laboratory. These options allow clinicians and laboratories to configure Scan Ladder according to their specific full-arch implant and restorative requirements. The manufacturer recommends purchasing the appropriate Scan Ladder Guide together with the selected kit at checkout, as the guide is required for the corresponding workflow.
Scan Ladder Options
- Scan Ladder Titanium Direct — the main reusable titanium full-arch scanning kit.
- TissueSync Scanbody Set — designed to improve matching between implant-position data and soft-tissue anatomy.
- Scan Ladder INDIRECT Kit — a single-use scanning device that locks onto and assists in scanning third-party scanbodies.
- GuideLock™ System — fiduciary marker kits designed to support the full Scan Ladder workflow.
- LabSync — laboratory scanbody components designed to extend the Scan Ladder workflow into the dental laboratory.
Scan Ladder Workflow
The Scan Ladder Titanium Direct system is designed to attach directly to multi-unit abutments. Its current kit contains six individually shaped matt-titanium scanbodies and six screws. Each scanbody has a different geometry, allowing the scanner or CAD software to distinguish the individual components and helping reduce confusion between identical scanbody shapes.
The workflow is fundamentally IOS-based.
First, the Scan Ladder components are connected to the multi-unit abutments. The clinician then performs the intraoral scan using a compatible intraoral scanner. Scan Ladder’s current design incorporates a patented random surface intended to improve the ability of the scanner to connect successive scan frames.
The system also incorporates a Common Matching Cylinder. Two of the newer scanbody shapes are elongated, allowing clinicians to position the scanbodies centrally and begin the scan around the middle of the arch before extending toward the posterior regions.
This central-focus approach is particularly relevant to full-arch implant cases because it attempts to minimize the distance between early scan frames and create a stronger reference relationship before scanning the remainder of the arch.
Scan Ladder describes the Titanium Direct system as an open workflow that can be used with different scanners and is not tied to a particular laboratory. The system also supports current CAD libraries, including Exocad and 3Shape workflows.
For clinicians performing immediate-load full-arch restorations, this can create a highly digital workflow from implant scanning through CAD design.
Scan Ladder Pros
Open IOS Workflow
One of Scan Ladder’s strongest advantages is its open approach. Rather than requiring a proprietary intraoral scanner, the system is designed to work with different IOS platforms.
This is particularly useful for dental practices that already own an IOS and want to improve full-arch implant scanning without purchasing an entirely new scanning platform.
Individual Scanbody Geometry
Each Titanium Direct scanbody has an individual shape. This is an important design characteristic because the software can distinguish different scanbodies rather than relying on multiple identical components.
Random Surface Technology
Scan Ladder uses a patented random surface designed to provide additional topographical information for the scanner. According to the manufacturer, this helps scan frames connect more reliably in edentulous full-arch situations.
Central-Focus Scanning
The central-focus workflow is another significant feature. By positioning suitable scanbodies toward the centre of the arch, the clinician can begin scanning from a compact area before extending the scan across the arch.
Clinical Evidence
Scan Ladder has an important advantage in terms of published evidence. The manufacturer reports an in-vivo peer-reviewed study comparing Scan Ladder-assisted scanning with the accuracy of intraoral and extraoral photogrammetry systems.
For clinicians evaluating new digital dentistry technologies, independent clinical evidence is an important consideration alongside manufacturer specifications.
Scan Ladder Cons
Despite its advantages, Scan Ladder is not necessarily the ideal solution for every clinician.
First, it remains fundamentally an IOS-based system. The accuracy of the final result therefore depends on the scanner, scanning technique, software workflow and clinical conditions. It is not a dedicated photogrammetry camera.
Second, the standard Titanium Direct kit focuses primarily on implant-position acquisition. Scan Ladder offers TissueSync as an additional solution for improving soft-tissue matching, meaning clinicians requiring a comprehensive implant-plus-soft-tissue workflow may need additional components.
Finally, clinicians must ensure compatibility between their implant/MUA connection, scanbody configuration and CAD library before beginning a case.
What is UltraFitScan?
UltraFitScan is an AI-powered full-arch reconstruction data acquisition system developed specifically for edentulous implant restorations and immediate full-arch workflows. Rather than functioning as a dedicated photogrammetry camera, UltraFitScan combines an intraoral scanner, encoded implant scanbodies, HS gingival scanning caps and dedicated software to acquire and match implant-position and soft-tissue data.
The UltraFitScan workflow begins by attaching the appropriate scanbodies to the multi-unit abutments and scanning them with an intraoral scanner. The scanbodies are then replaced with HS caps, which provide gingival soft-tissue reference points. The implant and gingival datasets are subsequently imported into the UltraFitScan software platform for data conversion and matching before the final file is exported to dental CAD software for restoration design.
According to the March 2026 manufacturer brochure, UltraFitScan’s scanning bodies are compatible with any intraoral scanner, while the UF-A and UF-B kits are claimed to cover more than 95% of implant systems. The manufacturer also states a scan-data error of ≤0.01 mm, although this should be regarded as a manufacturer specification rather than independently validated clinical accuracy.
For implantologists and prosthodontists, UltraFitScan represents an emerging approach to digital full-arch implant scanning, combining implant-position acquisition, gingival reference scanning and AI-assisted data matching within a single workflow.
UltraFitScan Kit & Components
UltraFitScan is available in two dedicated kit configurations — UF-A and UF-B — giving dental professionals the flexibility to select the appropriate system according to the multi-unit abutment connection used in the full-arch case. Both kits include 12 UltraFitScan scanbodies, available in S, M and L sizes, with four scanbodies of each size. The kits also include the corresponding HS gingival caps, fixation screws and screwdriver/hex components required for the scanning workflow. The key difference between the two configurations is the supported screw connection: UF-A covers M1.4 and M1.6, while UF-B covers M1.8 and M2.0.
UF-A — M1.4 / M1.6
The UF-A kit is designed for multi-unit abutments using M1.4 or M1.6 screw connections. It includes four S-size, four M-size and four L-size UltraFitScan scanbodies, providing different scanbody dimensions for varying implant positions and anatomical conditions. The kit also contains the corresponding M1.4 and M1.6 HS caps and screws, together with the required screwdriver/hex components.
UF-B — M1.8 / M2.0
The UF-B kit provides the same S/M/L scanbody configuration but is designed for M1.8 and M2.0 screw connections. It includes four scanbodies in each size, along with the corresponding HS caps and screws for the supported connections. This gives clinicians an alternative configuration when treating implant systems using larger MUA screw dimensions.
Multiple Scanbody Sizes for Clinical Flexibility
The availability of S, M and L UltraFitScan scanbodies is intended to accommodate different implant positions and anatomical structures. The manufacturer specifically highlights the multiple-size design as a way of providing greater clinical flexibility during full-arch implant scanning.
Both UF-A and UF-B are part of the same UltraFitScan ecosystem, and the manufacturer states that the two configurations together are compatible with more than 95% of implant systems on the market. The brochure provides an extensive list of compatible systems and MUA configurations, including Nobel, Straumann, Neodent, Osstem, Dentium, Megagen, MIS, Camlog, Zimmer, Alpha-Bio and others.
UltraFitScan Workflow
UltraFitScan takes a different approach to full-arch implant scanning.
According to the March 2026 UltraFitScan brochure, the system combines encoded scanbody technology with HS cap technology and is specifically designed for immediate edentulous implant restorations.
The workflow consists of four principal stages:
1. Intraoral implant scanning: The UltraFit scanbodies are installed onto the multi-unit abutments and scanned using an intraoral scanner.
2. Gingival scanning: The UltraFit scanbodies are replaced with suitable HS caps, which are then scanned to capture gingival soft-tissue reference points.
3. Data matching: The implant and gingival datasets are imported into the UltraFit software platform, where the data is converted and matched.
4. Restoration design: The resulting scan file can then be exported into dental CAD software for restoration design.
This is one of UltraFitScan‘s most interesting characteristics: the manufacturer presents it not simply as a set of scanbodies, but as a Full Arch Reconstruction Data Acquisition System.
AI-Powered Alignment Without Manual Stitching
One of the most significant advantages of UltraFitScan is its dedicated software-based alignment workflow. Instead of relying entirely on the conventional stitching process of an intraoral scanner across a long, edentulous arch, UltraFitScan uses advanced AI alignment algorithms to match the captured implant data.
This is particularly valuable in full-arch implant cases, where the lack of anatomical landmarks can make conventional IOS stitching more challenging and may introduce cumulative positional errors. UltraFitScan is designed to address this problem by using the scanbody data as dedicated reference information and performing automated data matching through its software platform. The manufacturer describes the system as using AI-powered scanning technology to precisely determine implant placement.
Free AI-Automated Alignment Software
UltraFitScan goes beyond simply providing specialized scanbodies. The system includes a dedicated AI-powered software platform for importing, converting and matching the acquired scan data before exporting the final file to dental CAD software.
This automated approach can significantly simplify the full-arch workflow by reducing the need for manual alignment and positioning of implant data. For implantologists and prosthodontists, this means a more streamlined digital workflow from implant scanning → AI alignment → CAD design.
Designed to Reduce Full-Arch Stitching Errors
Full-arch edentulous scanning presents a fundamental challenge: there are relatively few natural anatomical reference points for an IOS to use when stitching multiple frames together. UltraFitScan was specifically developed to address this limitation. The manufacturer identifies distorted or inaccurate image stitching as one of the principal problems encountered during conventional edentulous scanning.
By using dedicated scanbody markers and AI-based data matching, UltraFitScan provides the software with defined implant-position references rather than depending exclusively on the patient’s soft-tissue anatomy.
The practical benefit is a workflow designed to minimize the cumulative stitching errors that can occur when scanning across a completely edentulous arch.
Compatible With Nearly Any Intraoral Scanner
Another major advantage is hardware flexibility. UltraFitScan states that its scanbody is compatible with any intraoral scanner, allowing dental professionals to use their existing IOS rather than purchasing a dedicated scanner specifically for the system.
This makes UltraFitScan particularly attractive for practices that already use scanners from manufacturers such as Medit, Shining 3D, 3Shape, Dentsply Sirona, iTero, Runyes and other major IOS brands, provided the specific clinical workflow and software export requirements are supported.
More Than 95% Implant-System Compatibility
UltraFitScan is designed to provide broad implant compatibility. The manufacturer states that the UF-A and UF-B kits cover more than 95% of implant systems on the market.
The March 2026 brochure specifically lists compatibility with numerous systems, including Nobel, Straumann, Neodent, Osstem, Dentium, Megagen, MIS, Camlog, Zimmer, Alpha-Bio, Adin, Dentis and others.
For practices treating patients with different implant systems, this broad compatibility can eliminate the need to maintain multiple completely different digital acquisition workflows.
Integrated Implant and Gingival Scanning
UltraFitScan is not limited to implant-position acquisition. Its HS caps enable the clinician to capture gingival soft-tissue reference points after scanning the implant scanbodies.
The workflow therefore combines:
Implant position data + gingival anatomy → AI-assisted data matching → CAD-ready digital file
This can be particularly useful for immediate full-arch implant restorations, where accurate implant positioning needs to be combined with the patient’s gingival anatomy for prosthetic design.
Reduced Scanning Area and Faster Data Acquisition
UltraFitScan also aims to reduce the amount of intraoral scanning required. The manufacturer states that only the markers need to be scanned, reducing the scanning area and potentially shortening acquisition time.
For a clinician performing multiple full-arch implant cases, reducing the amount of scanning required can translate into a more efficient chairside workflow and less time spent acquiring digital impressions.
Precision Titanium Scanbodies
UltraFitScan scanbodies are manufactured from TC4 ELI titanium, using integrated forming and high-precision machining. The manufacturer states that component manufacturing tolerances are within 0.005 mm (5 µm).
The manufacturer also states that UltraFitScan can capture scan data with an error of ≤0.01 mm (≤10 µm).
These figures should be presented as manufacturer-stated specifications, rather than independent clinical validation.
A Complete Digital Full-Arch Acquisition Workflow
Perhaps the biggest advantage of UltraFitScan is that it combines several technologies into one workflow rather than simply providing another set of implant scanbodies.
The complete process is:
UltraFitScan scanbodies → IOS acquisition → AI-powered alignment and data matching → HS cap gingival scan → CAD-ready output
The manufacturer explicitly describes the output file as being suitable for import into any dental CAD software for final restoration design.
For modern implantologists, prosthodontists and digital dental laboratories, this creates a compelling alternative to conventional full-arch IOS stitching and a potentially cost-effective alternative to purchasing a dedicated dental photogrammetry camera.
UltraFitScan Cons
UltraFitScan is an impressive new technology that was just launched in June 2026, so clinicians should consider several factors before adopting it.
A Newly Launched Technology
One of the main considerations is that UltraFitScan is a newly launched product. As a result, it does not yet have the same volume of long-term clinical experience or independently published research as more established full-arch implant scanning technologies such as Scan Ladder.
This does not necessarily indicate a limitation in the technology itself. In fact, the development approach suggests the opposite. The manufacturer has specifically invested approximately USD $290,000 in developing the dedicated UltraFitScan software, which is purpose-built for full-arch implant alignment rather than being a generic scanning or CAD application.
This is significant because the manufacturer has focused the software development specifically on one of the most challenging problems in digital implant dentistry: accurately determining and aligning multiple implant positions across a completely edentulous arch.
Independent Clinical Evidence Is Still Developing
UltraFitScan states a scan-data error of ≤0.01 mm (≤10 µm). However, this should currently be regarded as a manufacturer-stated specification, rather than an independently validated clinical accuracy figure.
Because UltraFitScan is new, clinicians should distinguish between the impressive technical specifications of the system and the amount of independent, peer-reviewed clinical evidence currently available.
That said, the substantial investment in dedicated alignment software demonstrates that the manufacturer has taken the accuracy challenge seriously. Rather than simply producing another set of implant scanbodies, Chirimen has developed a dedicated AI-powered alignment platform specifically for full-arch implant positioning. The brochure describes the software workflow as importing, converting and matching the acquired datasets before producing a file suitable for dental CAD software.
A Serious Attempt to Solve a Difficult Clinical Problem
Ultimately, the fact that UltraFitScan is new should not overshadow what makes the technology interesting.
Full-arch implant alignment is one of the most technically demanding applications of intraoral scanning. The absence of anatomical landmarks, long scanning paths and the potential accumulation of stitching errors can make accurate implant-position acquisition challenging. UltraFitScan was specifically developed around these problems.
The manufacturer’s reported USD $290,000 investment in dedicated software development and the decision to build a software platform specifically around full-arch implant alignment demonstrate a substantial commitment to addressing this challenge.
Therefore, rather than viewing UltraFitScan’s newness simply as a disadvantage, it may be more appropriate to see it as an emerging technology backed by a significant development effort, with clinical adoption and independent validation expected to provide a clearer picture of its long-term performance.
For dental professionals considering UltraFitScan today, the sensible approach is to recognize both sides: it is a new system with limited independent clinical evidence, but it has been purposefully engineered around one of the most frustrating accuracy challenges in full-arch digital implant dentistry.

UltraFitScan vs Scan Ladder: Which Should You Choose?
There is no universal winner.
For clinicians who prioritize independent clinical evidence, an open IOS workflow and a highly developed full-arch scanning methodology, Scan Ladder is an attractive option.
For clinicians who prioritize AI-assisted data matching, encoded scanbodies and integrated gingival-reference acquisition, UltraFitScan offers a compelling alternative.
The two technologies should therefore be viewed as competing approaches to the same fundamental challenge: obtaining accurate implant-position data from edentulous full-arch cases without relying entirely on conventional impression techniques.
For implantologists and prosthodontists, the decision should ultimately consider implant-system compatibility, existing IOS equipment, CAD workflow, soft-tissue requirements, clinical evidence, training and total acquisition cost.
A Glimpse at Dental Photogrammetry Cameras
Specialized dental photogrammetry cameras take a different approach.
Instead of asking an intraoral scanner to reconstruct a long edentulous surface, a dedicated photogrammetry system captures the spatial relationship between specialized implant markers using multiple photographic measurements.
This can provide an extremely efficient method of acquiring implant positions for full-arch implant restorations.
A dedicated photogrammetry camera can therefore complement — rather than replace — an intraoral scanner. The photogrammetry system captures the highly precise implant-position dataset, while the IOS can subsequently capture the gingiva, teeth, soft tissue and prosthetic anatomy.
This combination can be particularly powerful for demanding All-on-4, All-on-6 and All-on-X workflows.
Runyes iGrapher G6: A Dedicated Dental Photogrammetry Solution
For dental professionals looking to move beyond IOS-assisted full-arch implant scanning, the Runyes iGrapher G6 is a dedicated dental photogrammetry camera worth considering.
Runyes classifies the iGrapher G6 specifically under its Photogrammetry Camera category.
According to Runyes, the iGrapher G6 provides:
- 20–30 μm position measurement accuracy
- Measurement of 2–8 points
- 90 × 90 × 50 mm measuring space
- 260 mm measuring distance
- Approximately 20 seconds for a half-arch impression
- 1.3 kg weight excluding the bracket
- 2500 mAh battery
- 15 V / 1.5 A input voltage.
For a dental practice performing full-arch implant rehabilitation, the attraction is straightforward: instead of relying solely on the stitching capabilities of an IOS across a feature-poor edentulous arch, the iGrapher G6 is designed specifically to acquire implant-position information through photogrammetric measurement.
Why Consider Photogrammetry?
For demanding full-arch cases, implant position is not simply another part of the digital impression. It is the fundamental spatial reference on which the passive fit and accuracy of the definitive prosthesis depend.
That makes the choice between an enhanced IOS workflow such as Scan Ladder or UltraFitScan and a dedicated photogrammetry camera such as the Runyes iGrapher G6 an important clinical and technological decision.
Scan Ladder and UltraFitScan represent the growing generation of IOS-assisted full-arch acquisition technologies. Dedicated photogrammetry represents the alternative approach: use a purpose-built measurement system for implant positioning and an IOS for the surrounding oral anatomy.
For practices performing a high volume of All-on-4, All-on-6 and All-on-X cases, understanding both approaches allows clinicians to select the workflow that best matches their clinical protocols, equipment and restorative ecosystem.
The future of full-arch implant dentistry is increasingly digital — and accurate implant-position acquisition is at the centre of that transformation.
For dental surgeons, implantologists and prosthodontists evaluating the latest 3D dental technologies, comparing systems such as Scan Ladder, UltraFitScan and Runyes iGrapher G6 is therefore not simply a comparison of products. It is a comparison of three different approaches to solving one of the most important challenges in digital full-arch dentistry: capturing implant position accurately, efficiently and predictably.
