Abstract

The invention discloses an in-place direction algorithm, a terminal and a storage medium. The method comprises the following steps that a dental crown grid surface and a false tooth grid model centralpoint are obtained in a false tooth grid model; the dental crown grid surface is divided into a plurality of first regions; any point in the first area is selected as a first vertex of the first area, and the direction from the first vertex to the center point of the false tooth grid model is used as a first candidate in-place direction; first undercut areas of the dental crown grid surface are obtained in the first candidate in-place direction according to the first vertex, the center point of the false tooth grid model and the dental crown grid surface; and the first candidate in-place direction corresponding to the smallest first undercut area in the first undercut areas of the dental crown grid surface is used as the final in-place direction of the false tooth grid model. According tothe in-place direction algorithm, the terminal and the storage medium, the problem of low accuracy of the false tooth in-place direction generated in existing false tooth design software is solved.

Description

technical field [0001] The invention relates to the field of computer-aided design, in particular to an in-position direction algorithm, a terminal and a computer-readable storage medium. Background technique [0002] The in-position direction of the denture generated in the existing denture design software is often equal to the direction of the long axis of the tooth, or the line connecting the center point of the shoulder outer edge line of the denture and the occlusal margin line is used as the in-position direction. The placement direction of the dentures is often not accurate enough, and it is not the optimal placement direction. The dentures are inserted into the preparation along the designed placement direction, resulting in poor adhesion between the denture and the preparation. Contents of the invention [0003] The main purpose of the present invention is to propose an in-position direction algorithm, a terminal and a computer-readable storage medium, aiming at s...
