Problems solved by technology

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] Studying the occlusal relationship and condyle position changes in patients with malocclusion is beneficial to the study of maxillofacial development and structural characteristics of patients. Based on this, the inventor proposes a temporomandibular joint measurement method.

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

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

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

[0032] As an implementation method, the CR jaw position and CO position of the patient are determined and fixed by biting the wax method (wax). i.e. duplication and transfer through bite registration wax. For example, fold the Delar occlusal wax after a warm water bath at 60°C into two layers and place it on the bil...

Abstract

A temporomandibular joint measurement method and an occlusal plate preparation method belong to the field of oral medicine. The temporomandibular joint measurement method includes: obtaining a patient's oral model; determining the patient's target image through the oral model, and separating the upper and lower jaws based on the target image to free the mandible. By matching and overlapping the crown images in different jaw positions with the corresponding crown images, the free mandible is guided to the corresponding jaw position to determine the temporomandibular joint image. The measurement method provided by the invention has the advantages of low cost, high efficiency and accuracy, and is beneficial to orthodontic treatment of patients with temporomandibular joint disorders.

Description

technical field [0001] The invention relates to the field of oral medicine, in particular to a method for measuring a temporomandibular joint and a method for preparing a splint. Background technique [0002] The temporomandibular joint, which can be referred to as the mandibular joint for short, is the only left-right bilateral linkage joint in the maxillofacial region, which has certain stability and multi-directional mobility. Various important activities related to chewing, swallowing, language, and facial expressions are produced under the action of muscles. The temporomandibular joint is composed of the mandibular fossa of the temporal bone, the articular tubercle, and the mandibular head. The joint capsule is lax, weak anteriorly, and laterally reinforced by ligaments. 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 combined joint that moves on both sides simultaneously, a...
