Tracing device and method for dentition movement trajectory

Abstract

The present invention provides a tracking device and method for dentition movement trajectory. The device includes an intraoral fixation component and an extraoral movement marking component. The intraoral fixation component includes a lower dentition base, a left retaining steel wire, a right retaining steel wire and Positioning steel wire, the lower dentition base is set on the lingual side of the lower dentition and extends from the mandibular incisors to the distal end of the last tooth on the left and right sides and is close to the lingual mucosa, the left retaining wire, the right The retaining steel wires are symmetrically distributed left and right; the extraoral movement marking components include connecting rods and arc rods. This kind of tracking device for the movement trajectory of the dentition adopts a personalized intraoral fixation component that is adapted to the individual dentition and does not cover the occlusal surface of the upper and lower jaw dentition. Therefore, when the movement of the dentition is collected, the occlusal surfaces of the upper and lower dentition can be in direct contact, and there is no vertical gap between the upper and lower dentition, which accurately transfers the movement process of the dentition and does not affect the tracing of the movement trajectory.

Description

technical field [0001] The invention relates to a tracking device and method for the movement trajectory of dentition. 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. I...

Problems solved by technology

[0006] The object of the present invention is to provide a dentition movement indicating device and 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 existing in the prior art. The problem of not being able to accurately display the movement of the dentition
