A algorithm for 3D reconstruction of artificial teeth / 实用口腔医学杂志

Objective: To reconstruct three dimension (3D) model of a rtificial tooth and to establish standardized 3D artificial teeth graphic datab ase. Methods: Artificial teeth were incised with CGI autom atic cross section scanning instrument, then data points were picked up from e ach parallel layer contour of incised tooth, and 3D stereo models of artificia l tooth were retrieved using 3D reconstruction techniques. Results: 3D graphic models of 28 artificial teeth were established.The models may represent the graphic feature of the teeth. Conclusion: The present technic is feasible in the establishment of 3D graphic models of artificial tooth.
