An orthodontic method and device based on artificial intelligence

Abstract

The present invention provides an orthodontic method and device based on artificial intelligence. The method includes acquiring marked oral CT image data; the marked oral CT image data circles the tooth area on each frame of image in the form of marking; The circled area is marked with the corresponding tooth number, and the non-tooth area is set to 0; the marked oral CT image data is input into the second generator to obtain an orthodontic scheme characterized in coded form; according to the orthodontic scheme, combined with the A printable dentition model is obtained from the three-dimensional digital model of the teeth obtained by annotating the oral CT image data; an appliance is manufactured based on the dentition model. The present invention uses a variety of machine learning models, realizes the automation of the whole process from three-dimensional digital acquisition of teeth to model manufacturing, is not easily affected by the subjective influence of individual doctors, and can also improve the efficiency of diagnosis and treatment.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to an orthodontic method and device based on artificial intelligence. 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 malformation has 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. Orthodontics is aimed at tooth alignment deformity or malocclusion, using fixed orthodontic appliances composed of arch wires, brackets, etc., or invisible removable orthodontic appliances such as braces, to apply three-dimensional orthodontic force and torque to teeth, and adjust facial bones, teeth and The balance and coordination among the three maxil...

Problems solved by technology

In order to obtain the three-dimensional model data of teeth required for orthodontic treatment, in the prior art, it is usually necessary to rely on professional 3D scanning equipment to obtain tooth image data. 3D scanning equipment is expensive, and the acquisition cost of image data is too high, which will inevitably increase the and the burden of users; while the accuracy of CT images with high popularity and relatively low cost is not high, it is difficult to obtain accurate 3D model data based on CT images, and it also needs to rely on manual intervention

[0005] Further, the artificial orthodontic solution in the prior art is limited by the professionalism of the doctor, therefore, the effect of the orthodontic solution is difficult to guarantee, and it cannot be displayed to the user in the form of a dynamic image, which is also not conducive to the user's understanding of the orthodontic process
