Methods and systems for determining occlusal contacts between teeth of a subject

摘要

A method and a system for determining occlusal contacts between lower teeth and upper teeth of a subject are provided. The method comprises: receiving a 3D model including a first portion and a second portion including points respectively representative of the lower teeth and the upper teeth; determining an occlusal plane associated with the second portion of the 3D model; determining, from each point of the first portion, respective distance values to the occlusal plane; and identifying, within the points of the first portion, based on the respective distance values, using a voxel grid, a set of occlusal points representative of at least some of the occlusal contacts between the lower teeth and the upper teeth.
