Method for three-dimensional configuration high-efficiency digital optimization after treatment of malocclusion dentitions

Abstract

The invention relates to a method for three-dimensional configuration high-efficiency digital optimization after treatment of malocclusion dentitions. The method comprises the following steps: (1) scanning dentitions of normally-occluded upper and lower jaws in batches as standard template data, and establishing a dental arch curve; (2) carrying out three-dimensional scanning on the malocclusion dentition requiring orthodontic treatment as data D1; (3) selecting a set of data from the step (1) as data D2; (4) registering the data D2 to the data D1 with the upper jaw palatal rugae as a common area; (5) extracting the three-dimensional data of the crown and root of each tooth in the data D1, registering the three-dimensional data to the corresponding teeth of the data D2, and generating preliminary preferred result data; (6) adjusting the contact relationship of the mesial and distal of the crown of each tooth, and generating the final preferred result data; and (7) making a female moldafter three-dimensional printing of the preferred result data, and directly presenting an entity of the preferred result in an oral cavity model of a patient. The method can realize the digital orthodontic diagnosis and treatment process and improve the functional aesthetic preference level of an operator.

Description

technical field [0001] The invention relates to a digital priority method after malocclusion dentition correction, in particular to a high-efficiency digital priority method for three-dimensional shape after malocclusion dentition correction. Background technique [0002] In the prior art, the preferred method of malocclusion dentition correction generally needs to be completed with the experience of doctors. The problems are: first, the process of making three-dimensional shapes after dentition correction is relatively complicated and prone to errors; second, it takes a long time The third is that the dentition with priority beautification cannot be obtained; the fourth is that it cannot be used in the digital orthodontic diagnosis and treatment process, and the functional aesthetics optimization level of the operator cannot be improved. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency digital optimization method for ...
