Abstract

The purpose of our study is measurement of the value of the translation and the rotation between the corresponding teeth of digital dental models before and after an orthodontic treatment. We used digital models from plaster models digitized by 3D scanner, and divide the polygons into several teeth using our original GUI. We measured the distance from a polygon in the jaw before the treatment to the nearest polygon in the after jaw and consider the distance as a fitness value. We got the best motion (translation and rotation) parameters using GA and reported them as the measurement of the tooth motion after the treatment. And we checked the accuracy of the result
