Intraoral disposable Gothic arch tracer and determination method of median relation

Abstract

The invention discloses an intraoral disposable Gothic arch tracer. The intraoral disposable Gothic arch tracer is simple in structure and low in manufacturing cost, the probability of clinical cross infection is reduced due to disposable use, and the intraoral disposable Gothic arch tracer is convenient to popularize and use in a large-scale oral outpatient service; the clinical operation process of determining the median relation of a patient without a tooth jaw by using the arcograph is simple and convenient, the vertical height is adjusted in a modularized mode, the accuracy is 0.5mm, the clinical requirements are completely met, the clinical operation is facilitated, three contour tracing needles which are arranged in a triangular mode ensure the balance and stability of a tracing plate, finally the stability of the median relation is ensured, the tiny deviation of the upper jaw position and the lower jaw position which may exist in the fixation of a conventional intraoral Gothic arch tracer tracing needle is overcome, and the wax bank manufacturing of the upper jaw is completed in advance, so that the accurate positions of the upper closed frame and the artificial tooth arrangement are convenient to transfer by the face arch.

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...

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 inve...
