Abstract

The invention discloses a method and device for generating an indirect orthodontic adhesive transfer tray three-dimensional digital model, relates to the field of digital medical treatment, and aims at solving the problem of an inaccurate orthodontic result. The method comprises the following steps: obtaining original dentition data with radix dentis and skull data; obtaining data feature points; generating a skull side head shadow image according to skull feature points; generating an occlusal surface and teeth arrangement arch wires of upper and lower jaws according to tooth feature points and the skull side head shadow image; generating an oriented bounding box of each tooth according to the tooth feature points; carrying out automatic teeth arrangement according to the oriented bounding box of each tooth and a preset orthodontic rule, and generating expected orthodontic dentition; arranging brackets on the teeth in the expected orthodontic dentition according to the oriented bounding box of each tooth and generating the expected orthodontic dentition with the brackets; and generating the transfer tray three-dimensional digital model according to the expected orthodontic dentition with the brackets. The method and the device disclosed by the invention are mainly applied to the tooth orthodontic process.

Description

technical field [0001] The invention relates to the field of digital medical care, in particular to a method and device for generating a three-dimensional digital model of an orthodontic indirect bonding transfer tray. Background technique [0002] Oral cosmetology involves comprehensive medical care and health care for lips, teeth, and gums. The beauty of lips mainly improves lip shape and lip line, the beauty of teeth mainly improves the arrangement, color and shape, and the beauty of gums mainly improves shape and health status. Improving the beauty of teeth mainly includes orthodontics, tooth restoration and tooth whitening. Orthodontics is the straightening of teeth, removal of malocclusions and deformities. Orthodontics mainly focuses on the diagnosis, analysis, prevention and treatment of malocclusion and deformity. [0003] The digital orthodontic software first takes the intraoral scan model of the patient's dentition as the input model, and outputs a three-dimens...
