Dental three-dimensional data processing device and method

Abstract

The present invention relates to a three-dimensional data processing device for dentistry and its method. By combining and aligning tooth data with image data of the scanned face, the occlusal state of the teeth is judged, and tooth models are generated by analyzing the movement of the teeth or temporomandibular joints, thereby It can diagnose the state of teeth more accurately and precisely, and analyze the occlusal state according to the movement of teeth and temporomandibular joints, and can accurately analyze the patient's state based on the motion and occlusal state to establish a treatment strategy, and can generate a treatment strategy suitable for the patient's state Dental models and corrections can be made to improve treatment outcomes.

Description

technical field [0001] The present invention relates to a three-dimensional data processing device for dentistry and its method, in particular to a method capable of diagnosing the occlusal state and analyzing teeth and temporomandibular joints based on tooth data and image data about the face. Dental three-dimensional data processing device and method for joint motion. Background technique [0002] In general, human teeth are connected to the temporomandibular joint and have complex motions according to the degree and direction of motion of the temporomandibular joint. [0003] In particular, when the movement of the temporomandibular joint deviates from the normal movement, it will affect the occlusion with the tooth model, so it is necessary to judge its movement. [0004] Conventionally, in order to diagnose a patient with a problem with the temporomandibular joint, after generating a tooth model, the tooth model is attached to an articulator, and information about the ...

AI Technical Summary

Problems solved by technology

[0005] However, different people have different TMJs and occlusal states of teeth, and different chewing habits, but the articulator has a predetermined shape and cannot correspond to all people, so even if the tooth model is corrected based on the information about the occlusal state extracted from the articulator , and used for the treatment of patients, there are limitations when applied to all patients

[0006] In order to solve the above problems, it is proposed to install a predetermined device in the patient's mouth and track its movement. However, the patient will feel uncomfortable, and since the device is inserted into the oral cavity, it hinders the movement of the teeth and cannot extract accurate movement, so it is difficult. make a diagnosis
