A Disposable Gothic Bow Tracer in the Mouth and a Method for Determining Median Relation Position

Abstract

The intraoral disposable gothic arch tracer of the present invention has simple structure, low cost, and one-time use reduces the chance of clinical cross-infection, and is convenient for popularization and use in a wide range of oral clinics; use the arch tracer to determine the median position of edentulous patients The clinical operation process is simple, the vertical height can be adjusted modularly, and the accuracy is 0.5mm, which fully meets the clinical needs and is convenient for clinical operation. The three contour tracing needles arranged in a triangle ensure the balance and stability of the tracing board, and finally guarantee It ensures the stability of the median relationship and overcomes the slight deviation of the upper and lower jaw positions that may exist in the conventional Gothic arch monographic needle fixation. The upper jaw is pre-finished with wax embankments to facilitate the transfer of the facebow to the upper joint frame and the accurate position of the artificial teeth arrangement.

Description

technical field [0001] The invention relates to an intraoral disposable gothic arch tracer and a method for determining the median relation position of an edentulous patient by using the intraoral gothic arch tracer. Background technique [0002] my country has entered an aging society, the proportion of the elderly is increasing year by year, and there are more and more edentulous patients. Whether it is making conventional complete dentures or implant denture restorations, determining the correct position of the patient's lower jaw relative to the upper jaw, that is, the centric relationship, is the key to whether the patient's oral and jaw physiological functions such as chewing can be restored. [0003] When determining the median relationship in clinical routine, the doctor usually determines the vertical distance based on experience, and then guides the patient's mandibular condyle to the uppermost and anterior position of the temporomandibular joint to determine the h...

AI Technical Summary

Problems solved by technology

[0006] In view of the above difficulties in determining the median relationship of patients with edentulous jaws and too many missing teeth, the original Gothic arch has a complex structure, high cost, cumbersome clinical application procedures, and sensitive single-point fixation technology, which cannot be applied to the majority of grassroots hospitals and young people. To improve the deficiencies of use, the invention provides a disposable gothic bow tracing instrument in the mouth with simple structure, multi-point tracing, stability, low cost, convenient use and low technical sensitivity. The disposable gothic arch tracing instrument , to avoid cross-infection, facilitate the use of young clinical doctors and doctors in primary hospitals, accurately determine the median relationship of patients, and produce high-quality dentures
