Quantification of 3d tooth movement after a segmentation using a Watershed 3d method

Abstract

In life we find a lot of several problems that touch all domains. One of them is dental medicine, which was crashing into the mechanical treatment. Nowadays, the appearance of computers in orthodontics has provided a solution to various problems and has facilitated many operations. The objectives of this study is to find a virtual approximation to real orthodontics problems of teeth movement based on digital images take it with cone-beam computed tomography (CBCT) using a different methods to define the transformation that teeth must follow to return to the natural state started by a segmentation using one of the most important method named Watershed. All components of teeth displacement are combination of translations and rotations movement along the three axes. The result showed that the forces applied to the teeth in some positions could decrease number of translations and rotations to the decrease in simulation time.
