This paper presents the computerized segmentation algorithm on the 3D digital dental model for separating individual tooth using Borland C++ Builder® and OpenGL. The purpose is to apply the algorithm in the 3D orthodontic diagnosis and treatment software package. The method consists of 5 main steps as follows. First the digital dental model is produced by 3D scanner in STL format and the occlusal...
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...
