The evolution and the future of Clear Aligners

I have been fortunate to witness the evolution of Clear Aligners from their inception, and this article serves as an informative guide for those interested in understanding their journey from the past to what lies ahead.

The article begins by highlighting the surging demand for clear aligner treatment, with the clear aligner market projected to reach approximately USD 11.6 billion by 2027. This trend underscores the need for businesses to stay updated with emerging technologies in order to remain competitive in this growing market.

A crucial point raised in the article is that the effectiveness of clear aligner treatment is closely linked to the evolving technology and materials.

The historical journey of clear aligners, dating back to Kesling in 1945 and culminating in the creation of Invisalign in 1998, transformed the field of orthodontics. Since then, there has been continuous evolution from the first generation of aligners. Our understanding, technology, and materials have evolved, resulting in better and more efficient clinical outcomes. Today, we stand on the cusp of a new revolution, as 3D printed materials are poised to replace the current thermoformed aligners.

The mechanical properties of the recently released TC-85 (Graphy) material promise a revolution in several crucial aspects:

1. Memory-Shape Property: This feature could enhance the efficiency of each aligner in delivering forces, potentially reducing treatment time and improving outcomes.

2. Environmental Benefits: 3D printing aligners reduces waste as we no longer need to print and discard models. Additionally, fewer aligners are required for each patient.

3. Health: What about the microplastics released by clear aligners?

4. Easy Disinfection: These aligners can be disinfected at high temperatures, making them easier to maintain and keep clean.

5. In-Office Printing: The ability to print these aligners in the office provides greater control and flexibility.

 

As clinicians, our aim is to provide the best possible treatment outcomes to our patients. Clear aligners have become a mainstream orthodontic option, and it's imperative that we embrace this technology for most cases. Moreover, as responsible global citizens, we should consider the positive environmental impact of 3D printing technology in reducing our carbon footprint.

I can't wait for the development of further improvements to the current 3D printed aligner material, which will greatly help us in delivering amazing results for our patients whilst taking care of the future of our planet.

I encourage you to read the full article and share your thoughts on these exciting developments in clear aligner technology.
