But such frames are expensive, and most doctors can't afford them
Moreover, the transfer of the jaw position through the facebow is only performed on the outer movable soft tissues, such as the base of the nose and ear holes, which has a certain degree of error, which will affect the final measurement.

Embodiment 1

[0028] The study of the occlusal relationship and the changes of the position of the condyle in patients with malocclusion is beneficial to the study of the patient's maxillofacial development and structural characteristics. Based on this, the inventor proposed a temporomandibular joint measurement method.

[0029] The temporomandibular joint measurement method includes the following steps:

[0030] Step S101: Determine and maintain the CR jaw position and CO jaw position of the patient's mouth to the oral model.

[0031] By determining and maintaining the CR jaw position and CO jaw position of the patient's mouth, the oral cavity can be measured, such as scanning and photography.

[0032] As an implementation method, the bite wax method (wax) determines and fixes the CR jaw position and CO position of the patient. That is, copy and transfer by bite recording wax. For example, the Delar occlusal wax after a 60°C warm water bath is folded into a double layer and placed on both maxill...

Abstract

The invention relates to a measurement method for a temporo-mandibular joint and a preparation method of an intraoral splint and belongs to the field of oral medical treatment. The measurement method for the temporo-mandibular joint comprises the steps of obtaining an oral model of a patient, determining a target image of the patient via the oral model, separating an upper jaw and a lower jaw according to the target image to allow the lower jaw to be free, allowing dental crown images in different jaw position states to be matched and overlapped with a corresponding dental crown image, and guiding the free lower jaw to a corresponding jaw position to determine an image of the temporo-mandibular joint. The measurement method has the advantages of low cost, high efficiency and accuracy and facilitates orthodontics of a patient with temporo-mandibular disorders.

Description

Technical field [0001] The invention relates to the field of oral medicine, in particular to a method for measuring temporomandibular joints and a method for preparing occlusal plates. Background technique [0002] The temporomandibular joint can be referred to as the mandibular joint. It is the only left and right bilateral linkage joint in the maxillofacial region. It has a certain degree of stability and multi-directional mobility. Under the action of muscles, it produces various important activities related to chewing, swallowing, language, and expression. The temporomandibular joint is composed of the mandibular fossa, articular tuberosity and mandibular head of the temporal bone. The joint capsule is loose, the anterior part is weak, and the lateral ligaments are strengthened. There is an oval joint disc in the joint capsule, which divides the joint cavity into upper and lower parts. The temporomandibular joint is a joint joint. The simultaneous movement of both sides ca...
