Problems solved by technology
[0004] In view of the realization of the above-mentioned automatic analog tooth arrangement, the inventors found that the coding method of the existing automatic analog tooth arrangement method is poor for the tooth arrangement rules, and it is difficult to comprehensively encode the above-mentioned tooth arrangement rules into the automatic tooth arrangement design optimization algorithm , so the quality of the tooth arrangement results obtained by the automatic simulation of the tooth arrangement method is reduced

The invention discloses an automatic tooth arrangement simulating method and device and relates to the technical field of computers.The problem that the quality of a tooth arrangement result obtained through an existing automatic tooth arrangement simulation way is low is solved.The method comprises the steps that coordinates of orthodontic feature points of teeth in a dentition model are obtained; the PAR index is decomposed into distance types for a preset number of teeth for encoding, and automatic tooth arrangement simulating constraint conditions are generated; the constraint conditions and a force guiding algorithm are added into an ICP algorithm to figure out the target displacement vector of the orthodontic feature point of each tooth; the teeth are correspondingly moved according to the target displacement vectors, and a new dentition model is obtained; whether the tooth root of each tooth in the new dentition model is located in an alveolar bone line contour or not is judged; if one tooth root is not located in the alveolar bone line contour, the tooth, corresponding to the tooth root, in the new dentition model is moved around the crown, and a final dentition model is obtained.The automatic tooth arrangement simulating method and device are suitable for being applied to the tooth orthodontic process.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for automatically simulating tooth arrangement. Background technique [0002] In the field of orthodontics, the study of tooth arrangement methods has always been the focus of research. Before the doctor arranges the teeth of the patient, it is necessary to predict and evaluate the tooth arrangement plan first, and the prediction and evaluation of the plan are realized by simulating the tooth arrangement process. The traditional analog tooth arrangement method is based on the human-computer interaction analog tooth arrangement method based on the gypsum dentition model, and with the development of digital technology, the traditional analog tooth arrangement method is gradually being replaced by the automatic analog tooth arrangement method. The automatic simulation tooth arrangement method refers to the use of 3D digital imaging technology and 3D modeling t...
