temporomandibular joint: the mandibular joint for short consists of a mandibular condyloid process, a temporal bone joint surface, a joint disc between the condyloid process and the temporal bone joint surface, a joint capsule around the joint, joint ligaments and the like, wherein the joint ligaments comprise a temporal mandibular ligament, a sphenoid mandibular ligament and a styloid mandibular ligament and are used for suspending the mandible and maintaining the mandible to move within a normal range. The temporomandibular joint is a left and right bilateral linkage joint for jaw face displacement, has certain stability and multidirectional mobility, allows the mandible to be lifted, lowered, advanced, retreated and moved laterally, and realizes mouth opening, mouth closing and chewing movement under the action of masticatory muscles around the temporomandibular joint.
Dentition: it refers to an arch shape in which teeth are arranged in a certain order, direction and position on the upper jaw or the lower jaw, wherein the dentition on the upper jaw is called as the maxillary dentition, and the dentition on the lower jaw is called as the mandibular dentition. The upper jaw dentition and the lower jaw dentition are occluded together according to a certain corresponding relation, the concave-convex structures of the occlusion surfaces are closely contacted, and functional activities such as chewing and the like are completed in the repeated occlusion movement process of contact-separation-contact-re-separation.
Centering the jaw position: when the upper and lower jaw dentitions are contacted together, the anterior teeth are normally covered, and the posterior teeth are in a contact relationship of tip socket staggering, which is also called as tip socket staggering; the maxillomandibular relationship is now the most widely connected. Clinically, if there are dental caries, tooth loss, temporomandibular joint disorder inflammation, inflammation or loss of maxillary and mandibular bones, the relationship between the above-mentioned medial relation and the medial jaw position will be dislocated.
Median relation position: refers to the medial posterior position of the mandibular condyloid process in the glenoid fossa, while the physiological posterior position, in which the surrounding tissue is not constrained, is called the medial relationship position, also known as the ligamentous margin position. The neutral position is normally a tension edge position and is located within about 1mm behind the neutral jaw position.
