The method for reconstructing of interproximal tooth coating

The one side of the application provides a kind of method for rebuilding the adjacent surface of adjacent teeth in tooth three-dimensional mathematical model, including：Obtain tooth three-dimensional mathematical model comprising adjacent the first tooth and the second tooth, wherein first tooth and the second tooth locally link together, and the adjacent surface of the two coupling part is buried；Obtain the intersection point set of first tooth and the second tooth；It is fitted to obtain the first plane based on the intersection point set；Curvature operation is carried out to the region of the near intersections on first tooth, to determine the first control point set, which determines the boundary of the adjacent surface to be reconstructed of first tooth；And based on first plane and the first control point set, the first adjacent surface of first tooth is built with linear method.
