Customized temporomandibular joint repositioning occlusal pad and manufacturing and application methods thereof

Abstract

The invention provides a customized temporomandibular joint repositioning occlusal pad and manufacturing and application methods. The manufacturing method comprises the following steps: according to malocclusion conditions, determining the correction position of the lower jaw of a patient through the following three methods: muscle de-programming, forward stretching of the lower jaw to disappearance of springing of open and closed joints, and restoration of an articular disc, and acquiring upper and lower dentition data of the patient. The customized temporomandibular joint repositioning occlusal pad is manufactured on the basis of the correction position of the lower jaw and upper and lower dentition data and comprises an integrally formed occlusal pad body, and an upper tooth socket and a lower tooth socket are formed between a lip side wrapping surface and a tongue side wrapping surface of the occlusal pad body. The upper tooth socket and the lower tooth socket are respectively arranged on the upper side and the lower side of the occlusal pad body, a tongue side inclined surface is arranged below the tongue side wrapping surface, and the occlusal pad is particularly used for occlusal treatment of temporomandibular joint disorder caused by malocclusion and temporomandibular joint relocation after joint disc reduction.

Description

technical field [0001] The invention relates to the field of treatment of temporomandibular joint disorders, and is particularly suitable for joint repositioning treatment of temporomandibular joint disorders caused by malocclusion. Background technique [0002] The temporomandibular joint (TMJ) is the only left and right bilateral linkage joint in the maxillofacial region, which is used to open and close the mouth, protrude the mandible, retract and laterally, and masticate in daily life. Temporomandibular disorders (TMD) is a common disease of the oral and maxillofacial region, with an incidence rate as high as 33% in adults and 53.28% in orthodontic patients. [0003] The clinical manifestations of temporomandibular joint disorder are: pain in the joint area and its surrounding masticatory muscles, which may be accompanied by migraine, neck and shoulder pain, snapping or noise in the joint area, and abnormal mandibular movement (including limited mouth opening, mouth devi...
