Orthodontic method and device based on artificial intelligence

Abstract

The invention provides an orthodontic method and device based on artificial intelligence. The method comprises obtaining tagged oral CT image data, wherein the tagged oral CT image data circle the tooth area on each frame of the image in the form of an annotation; the circled area is marked with the corresponding tooth number, and the non-dental area is set to 0; the tagged oral CT image data is inputted into a second generator to obtain an orthodontic scheme represented in a coded form; according to the orthodontic scheme, a printable dentition model is obtained by combining the three-dimensional digital model of teeth obtained from the marked oral CT image data; an appliance can be made in basis of the model of the teeth. The device relates to multiply machine learning models and realizes automation of the whole process from 3D digitization of teeth to Model Manufacturing, which is not easily subject to the subjective influence of a doctor and capable of improving the efficiency of diagnosis and treatment.

Description

Technical field [0001] The invention relates to the technical field of tooth correction, in particular to an artificial intelligence-based orthodontic method and device. Background technique [0002] Oral disease is a common multiple disease. According to statistics from the World Health Organization, malocclusion has become one of the three major oral diseases (caries, periodontal disease and malocclusion). Tooth deformity has a great influence on oral health, oral function, maxillofacial bone development and appearance. Orthodontics has been considered an essential and important part of oral health treatment. Orthodontics is the use of fixed orthodontic appliances consisting of archwires and brackets, or invisible removable orthodontic appliances such as braces, to apply three-dimensional orthodontic force and torque to teeth to adjust facial bones, teeth and The balance and coordination between the three maxillofacial muscles can improve the facial shape, align the dentitio...

AI Technical Summary

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
