Abstract Scope |
The aim of this study is to determine the strain distributions within these aligners during application, with the long-term goal being to understand the movement of teeth induced by these devices.
The project contains two parts: simulation and experiment. Images of the aligner off and on the tooth model were processed by Digital Image Correlation (DIC) to obtain strain distributions for comparison with the finite-element (FE) prediction.
The strain (eyy) distributions from the simulation and experiment are compared. From the occlusal (top) and buccal (side) views, strain concentrations could be seen in the intercuspal and interproximal regions of the aligner in both the simulation and experiment. Strain concentration was highest in the anterior region.
The strain distributions from DIC validated the FE model of a clear teeth aligner for orthodontics. The forces induced on the teeth will be used to study tooth movement caused by the wearing of such devices. |
