Biomechanics of orthodonitc aligners: The constant refinement technique for optimum treatment

Maintaining control of tooth movement during orthodontic treatment using plastic aligners is not always easy. Some movements are difficult to achieve and many times do not express fully. Translation and troot movements are particularly challenging.
The constant refinement technique using in house aligners and differential staging may be able to improve the treatment process. Once correctly staged the aligners can be printed with Graphy or created from 3D printed models using a thermoforming technique
