Establishment of artificial-tooth three-dimensional coordinates based on dental anatomic concepts / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish a three-dimensional (3-D) descartes coordinates of artificial teeth based on concepts of dental anatomy and to obtain their geometric parameters.</p><p><b>METHODS</b>Using the 3-D reverse engineering software, artificial-tooth coordinates were defined based on their anatomic concepts which included long axis, mesiodistal and buccolingual directions, and occlusal plane. Some geometric parameters, such as mesiodistal and buccolingual dimensions, height and obliquity of dental cusp, were measured.</p><p><b>RESULTS</b>The 3-D coordinates of 28 artificial teeth were established and geometric parameters in coordinates were obtained.</p><p><b>CONCLUSIONS</b>The definition of artificial-tooth coordinates can be made using mathematic language based on dental anatomic concepts, which is the basal work of complete denture computer-aided design (CAD).</p>
