    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.

    摘要： A method produces a physical dental arch model having at least two physical tooth models. The method includes detecting the interference between two physical tooth models. If interference is detected between the first physical tooth model and the second physical tooth model, the positions and orientations of at least one physical tooth model is modified to prevent interference between the first physical tooth model and the second physical tooth model.

    摘要： Systems and methods for preventing interference between two physical tooth models in a physical dental arch model includes digitally representing the surfaces of each of the two physical tooth models by a mesh of points in three dimensions, interpolating the meshes of points to produce interpolated surfaces to represent the boundaries of the two physical tooth models, wherein the interpolated surfaces representing the boundaries of the two physical tooth models intersect at least at one point to form an overlapping portion. The method also includes specifying a straight line running through the overlapping portion and intersecting the two interpolated surfaces representing the boundaries of the two physical tooth models and calculating the length of the straight line in the overlapping portion to quantify the interference between the two physical tooth models.
