Dentition meshing stress index measurement and occlusion function pre-evaluation system and method

Abstract

The invention discloses a dentition meshing stress index measurement and occlusion function pre-evaluation system and method. An occlusion movement track is collected through a three-dimensional displacement sensor, and the occlusion movement track is measured through coordinate positioning and a face recognition camera; model reconstruction is performed on a three-dimensional dentition model, noise is removed, and smoothing and local restoration treatment is performed to obtain an upper and lower dentition overall model for engineering calculation; meshing stress distribution of dentitions ismeasured, processed and displayed, and data reconstruction and matching are performed on measured dentition data results; the meshing stress distribution of the dentitions is calculated and simulated; post-processing display is performed on the three-dimensional movement track of occlusion movement, and occlusion process kinematics analysis is performed; and the three-dimensional dentition modeland the kinematic analysis are digitized and parameterized, and dentition occlusion stress distribution simulation and verification are performed by adopting a numerical analysis method as a basic condition, so that personalized evaluation is provided for different occlusion functions.

Description

technical field [0001] The invention belongs to the technical field of dentition meshing detection, in particular to a system and method for measuring dentition meshing stress index and occlusal function pre-evaluation. Background technique [0002] At present, the occlusal function is related to the entire oral and jaw system: the temporomandibular joint, the occlusion of the teeth, and the muscles of the oral and jaw system. The health of the oral and jaw system can only be ensured when all parts are coordinated and coordinated. It is very important to develop a device and system for evaluating occlusal function. In fact, laser scanning, occlusal stress detector, electromyography, and mandibular trajectory tracing are used clinically to detect occlusal function. Each device has the characteristics of independence and joint use to varying degrees, but currently it can only be used as a doctor to evaluate occlusal function. At the time of reference, there is no method that...

AI Technical Summary

Problems solved by technology

At present, clinical evaluation of occlusal function basically relies on personal experience of doctors. There is no device and system for evaluating dental occlusal function. , specificity are far from the clinical needs, which is a highly empirical operation

Some electronic detection equipment can only analyze the occlusal movement process to a certain extent, and there is a certain deviation in the maxillofacial movement track information during occlusal, which affects the accuracy required for judging occlusal contact
