摘要:
Systems and methods are disclosed to prevent interference between two physical tooth models in a physical dental arch model by acquiring the coordinates of a plurality of points on the surfaces of each of the two physical tooth models and digitally representing the surfaces of each of the two physical tooth models by a mesh of points in three dimensions using the acquired coordinates. The meshes representing the surfaces of the two physical tooth models intersect at least at one point to form an overlapping portion. The method also includes calculating the depth of the overlapping portion between the two meshes to quantify the interference of the two physical tooth models.
