Denture movement trail indicator and tracking method

Abstract

The invention provides a denture movement trail indicator and a tracking method. The device comprises an intra-oral fixing assembly and a para-oral movement marking assembly. The intra-oral fixing assembly comprises a lower denture base, a left retention steel wire, a right retention steel wire and a positioning steel wire. The lower denture base is arranged on the tongue side of a lower denture,stretches from lower jaw incisor teeth to the far middles of last teeth on the left side and the right side and clings to mucosae on the tongue side. The left retention steel wire and the right retention steel wire are distributed in a left-and-right symmetry mode. The para-oral movement marking assembly comprises a connecting rod, an arc-shaped rod, an indicating plate and multiple straight cubepencil rods. According to the denture movement trail indicator, the personalized intra-oral fixing assembly which adapts to the personal denture conditions and does not cover the occlusion faces of upper and lower jaw dentures is adopted, thus, when denture movement is collected, the occlusion faces of the upper and lower dentures can be directly in contact, no vertical gaps exist between the upper and lower dentures, the movement process of the dentures is accurately transferred, and tracing of the movement trail is not affected.

Description

technical field [0001] The invention relates to a dentition movement trajectory indicator and a tracing method. Background technique [0002] Dentition movement is closely related to the healthy coordination of the function and structure of the oral and maxillofacial system. Analyzing and observing dentition movement is an important basis for oral medical diagnosis, implant restoration planning, orthodontic treatment plan formulation, and surgical effect evaluation. [0003] However, at this stage, the analysis of the movement of the dentition mainly relies on the doctor's clinical examination, the replica model of the dentition in the patient's mouth, and various image data of the patient's dentition in a static state. During clinical examination, due to the occlusion of the lip soft tissue, it is difficult to clearly expose the movement of the dentition to the doctor's field of vision. At the same time, the movement of the dentition is a complex dynamic process. It is di...

Problems solved by technology

[0006] The object of the present invention is to provide a dentition movement trajectory indicator and a tracing method, which can trace the dentition movement trajectory in the oral cavity outside the mouth, overcome the defect that the dentition movement trajectory cannot be directly observed, and solve the problems in the prior art. The problem of not being able to accurately display the movement of the dentition
