Method and device for determining occlusion relation of three-dimensional tooth model and storage medium

The invention discloses a method and device for determining the occlusion relation of a three-dimensional tooth model and a storage medium. The method comprises the following steps: acquiring a three-dimensional tooth model and a tooth area of the three-dimensional tooth model; based on the tooth area, performing tooth position alignment on the three-dimensional tooth model and the target tooth position to obtain an aligned three-dimensional tooth model; determining an initial occlusal relationship of the aligned three-dimensional tooth model, and generating a plurality of candidate occlusal relationships based on the initial occlusal relationship; and acquiring an occlusion relationship meeting a preset condition from the plurality of candidate occlusion relationships to obtain a target occlusion relationship. By means of the method and device, the problems that in the prior art, the mode for achieving occlusion alignment of the tooth model is complex, and the requirement for medical knowledge of operators i
