Method and system for detecting gap between adjacent regions of teeth in occlusion process

The invention discloses a tooth adjacent region gap detection method and system in an occlusion process, and belongs to the field of oral medicines.The method specifically comprises the steps that dental crown three-dimensional surface data and three-dimensional buccal side occlusion data of target teeth in an intraoral impaction region of a detector are collected; processing the three-dimensional scanning data to obtain three-dimensional surface data of a dental crown in an impaction area after occlusion; fusing the three-dimensional surface data of the dental crown of the impaction area before occlusion and the three-dimensional surface data of the dental crown of the impaction area after occlusion to obtain gap change characteristics of the front and rear tooth adjacent areas of the impaction area before and after occlusion; and obtaining the change of the adjacent region gap of the teeth before and after the impaction region or the teeth before and after the non-impaction region before and after occlusion
