Description

A tray structure for assisting lower jaw function motion

Technical Field

The utility model relates to the technical field of oral medical equipment, concretely relates to a tray structure for assisting lower jaw function motion.

Background

With the continuous improvement of the social living standard, the population ages gradually to appear the state of aging, and the lack of the oral health care consciousness leads to the increase of the patients without the tooth jaw in the whole mouth. The function of chewing the oral cavity has important significance for maintaining the capability of the human body required by normal life, so that the function of chewing the oral cavity has very important significance for manufacturing a practical complete denture for a complete edentulous jaw patient.

Generally, when a complete denture is manufactured for a complete edentulous patient, an important step is to acquire a mandible movement state and record a mandible movement track of the patient so as to ensure that the manufactured complete denture meets the mandible movement state of the patient and does not dislocate when the patient performs mandible movement. A common clinical method for obtaining the trajectory of the upper and lower jaws is the gothic arch method, which relies on the voluntary movement of the patient's lower jaw to obtain the trajectory of the lower jaw. However, the whole mouth edentulous patient is mostly a older patient, some patients have weak hearing, or are difficult to understand the meaning of a doctor, or lose jaw movement perception due to long-term tooth missing, the doctor needs to repeatedly teach the jaw movement mode of the patient repeatedly for multiple times, a large amount of clinical operation time is consumed, even the jaw function movement cannot be automatically completed according to the requirement of the doctor, the jaw movement relation is obtained in a deviation manner, the manufacture of the whole mouth denture is affected, the stability of the whole mouth denture during use is affected, and a large amount of clinical work time is also consumed.

Therefore, a tray structure for assisting the movement of the lower jaw function is needed to be designed, and the purpose is to solve the defect that the movement state of the lower jaw is difficult to obtain in the clinical operation process of the complete denture in the prior art.
