Shape Memory Aligners - The Next Generation of Aligner Orthodontics

3D Printed Shape-Memory Aligners are more versatile than conventional themo-pressure formed press aligners. When heated, the shape memory material temporarily increases in malleability, allowing for aligner coverage to the undercut, which in turn increases aligner hold and leads to more effective control of tooth movement. This presentation will discuss how shape memory aligners are used clinically. It will also present common issues with conventional themo-pressure formed aligners, and discuss solutions provided by shape memory aligners. In addition, the workflow of aligner creation using digital planning will also be introduced.
