Direct Printed Memory Aligners

What Are The Direct Printed Aligners ?

The direct printed aligners refer to a new-generation clear aligner that is fabricated directly through 3D printing, without needing a traditional thermoforming process over a dental model.

🦷 Here’s a breakdown of what makes it different:

🔸 Traditional Clear Aligners (like Invisalign or SureSmile):

1. A 3D model of the patient’s dentition is created.

2. Each aligner step is formed by thermoforming a plastic sheet over a printed dental model.

3. The aligner is then trimmed and polished.

🔸 Direct Printed Aligners:

1. Aligners are 3D printed directly in their final shape, layer by layer, using biocompatible resins.

2. No thermoforming or physical models needed.

3. Post-processing includes cleaning, curing, and polishing.

✅ Advantages of Direct Printed Aligners:

• Higher precision: Eliminates distortion from thermoforming.

• Better fit: Conforms more accurately to digital treatment plans.

• Faster production: Reduces steps in manufacturing.

• Potential for thinner, more comfortable appliances.

• Customization: Variable thickness and integrated features can be printed directly.

🔬 Materials:

• Typically made using biocompatible, flexible resins such as those developed by companies like SprintRay, Graphy, or Stratasys.

• Must meet ISO and FDA standards for intraoral use.

🚀 Clinical Applications:

• Used in orthodontics for mild to moderate tooth movement.

• Still being studied for long-term mechanical performance and force delivery compared to conventional thermoformed aligners.

● One of the many advantages of Direct-Printed Memory Aligners is that they eliminate the need for dental model printing; hence, the aligners are printed directly. Since thermoforming, cutting, and finishing are not required, almost no manufacturing errors occur during the manufacturing process, which increases accuracy considerably.

● It is possible to adjust the form and thickness of the aligners for each tooth surface to create the optimal orthodontic force. This is not possible
with conventional aligners.

● Decreasing manufacturing steps means reduced treatment time and more predictable/accurate results.

● Another important advantage is that minimal or no blockout of undercuts is required when producing the aligners.

● Also, heat disinfection to 100°C is possible with direct printed memory aligners, as it doesn’t permanently deform like the conventional aligners would. It returns to its original shape and mechanical properties.

● Increased comfort for the patients. Shape memory allows the patient to heat up and “soften” the aligner in warm water for easier insertion. The aligner will
regain its original and accurate fit when exposed to mouth temperature. The same method can be used to remove the aligner more easily.

● More aesthetically pleasing since no attachments are required in most cases

Direct Printed Aligners have been Endorsed by internationally renowned orthodontists.
For a summary of this global success- over 100,000 cases completed worldwide.

Some of the advantages over thermoforming aligners are:

Perhaps most notably, the direct printed memory aligners eliminate the need for attachments in most cases, offering a cleaner, more aesthetic solution. Additionally, it streamlines the process by reducing chair-side time and minimizing emergencies, allowing practitioners to focus on precision. Moreover, the system prioritizes higher accuracy through advanced technology, which translates to quicker results for patients. As a result, the experience becomes far more comfortable, reducing physical strain and anxiety. Simultaneously, it champions sustainability—unlike traditional methods, it skips printed models and slashes plastic waste, making it environmentally friendly. Not only does this innovation elevate patient care, but it also aligns with eco-conscious values, proving that efficiency and ethics can coexist seamlessly.
