Digital orthodontic tooth arrangement method based on tooth root information and bracket transfer device designing method based on digital orthodontic tooth arrangement method

Abstract

The invention discloses a digital orthodontic tooth arrangement method based on tooth root information and a bracket transfer device designing method based on the digital orthodontic tooth arrangement method. The digital orthodontic tooth arrangement method based on the tooth root information comprises the following steps that data are read in; a complete tooth model is guided in, and receiving data of the digital orthodontic tooth arrangement design include a skull STL model of a patient and a complete tooth STL model; characteristics of each tooth are extracted and include complete data of the dental crown and the tooth root; a tooth characteristic constraint database is built and includes a serial number of each tooth and coordinates and serial numbers of characteristic points in a point cloud model; digital lower jaw tooth arrangement is performed; digital upper jaw tooth arrangement is performed. The digital orthodontic tooth arrangement method based on the tooth root information is applied to an orthodontic treatment plan, parameterization comprehensive tooth arrangement of visualized adjustment of dental crown contact and tooth root postures is achieved, a bracket transfer device is designed after tooth arrangement is performed, and the digital orthodontic tooth arrangement method has the important application value in the computer-assisted orthodontic field.

Description

Technical field: [0001] The invention relates to a digital orthodontic tooth arrangement method based on tooth root information and a bracket transfer device design method based on the method, which belongs to the field of computer-aided design, and relates to the fields of reverse engineering and biomedical engineering. Background technique: [0002] Oral disease is a common multiple disease. According to the statistics of the World Health Organization, malocclusion has become one of the three major oral diseases (dental caries, periodontal disease and malocclusion). Dental deformities have a great impact on oral health, oral function, development and appearance of maxillofacial bones. Orthodontics has been recognized as an essential and important part of oral health care. Traditional orthodontic treatment mainly relies on the doctor's experience to formulate a treatment plan. Before the treatment plan is determined, the manual teeth arrangement experiment can help the o...
