Abstract

A method and device for segmentation and reconstruction of teeth and alveolar bone, wherein the method includes: segmenting a bone tissue area (101) in a three-dimensional CT image of the oral cavity; segmenting teeth and alveolar bone tissue from the bone tissue area Region (102); segment the two-dimensional outline of each independent tooth and the two-dimensional outline of alveolar bone (103) from the tooth and alveolar bone tissue area; reconstruct the digitization of each independent tooth according to the two-dimensional outline of each independent tooth A three-dimensional model, reconstructing a digital three-dimensional model of the alveolar bone according to the two-dimensional contour of the alveolar bone (104). This scheme can simultaneously segment the two-dimensional contours of the individual teeth and the two-dimensional contours of the alveolar bone, and then realize the reconstruction of the digital three-dimensional model of each independent tooth according to the two-dimensional contours of the individual teeth. The digital three-dimensional model of the alveolar bone is reconstructed from the contour to facilitate the realization of digital orthodontic treatment assistance.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a method and device for segmentation and reconstruction of teeth and alveolar bone. Background technique [0002] Malocclusions have a high incidence. In addition to affecting the appearance of the patient and causing psychological harm to the patient, it will also affect the development of the maxillofacial region and oral function and cause physical harm to the patient. Orthodontics is a discipline that specializes in the etiology, diagnosis, treatment and prevention of malocclusion. [0003] In traditional orthodontic treatment, the physical model of the jaw is an important tool to record the patient's medical record and express the shape of the patient's teeth, and it is also the most important way to reflect the real three-dimensional anatomical structure of the jaw. The measurement, analysis and operation of the physical model of the teeth and jaws are the main basis...
