摘要
Disclosed are a segmentation and reconstruction method and device for teeth and the alveolar bone. The method comprises: segmenting a bone tissue region from a three-dimensional CT image of an oral cavity (101); segmenting a tooth and alveolar bone tissue region from the bone tissue region (102); segmenting two-dimensional profiles of each individual tooth and two-dimensional profiles of the alveolar bone from the tooth and alveolar bone tissue region (103); and reconstructing a digitalized three-dimensional model of each individual tooth according to the two-dimensional profiles of the individual tooth, and reconstructing a digitalized three-dimensional model of the alveolar bone according to the two-dimensional profiles of the alveolar bone (104). The solution can simultaneously segment two-dimensional profiles of each individual tooth and two-dimensional profiles of an alveolar bone, and then reconstruct a digitalized three-dimensional model of each individual tooth according to the two-dimensional profiles of the individual tooth and a digitalized three-dimensional model of the alveolar bone according to the two-dimensional profiles of the alveolar bone to help to realize digitalized orthodontic treatment assistance.
