Detachable elastic traction occlusal pad and manufacturing method thereof

Abstract

The invention discloses a detachable elastic traction occlusal pad and a manufacturing method thereof, and relates to the technical field of temporomandibular joint dislocation treatment. The detachable elastic traction occlusal pad comprises an upper tooth socket, a lower tooth socket and traction components; each traction component comprises a first lingual button, a second lingual button and an elastic connecting piece; each first lingual button is fixedly connected with the upper tooth socket; each second lingual button is fixedly connected with the lower tooth socket; each first lingual button and each second lingual button are located on the same side of the upper tooth socket and the lower tooth socket; and one end of each elastic connecting piece is connected with the corresponding first lingual button, and the other end of each elastic connecting piece is connected with the corresponding second lingual button. The lingual buttons used for being connected with the elastic connecting pieces are arranged on the upper tooth socket and the lower tooth socket respectively, the maximum opening degree of a patient can be limited through the arrangement of the elastic connecting pieces, the maximum opening degree is effectively limited within the safe opening degree, temporomandibular joint dislocation is prevented, and meanwhile the treatment effect is achieved.

Description

technical field [0001] The invention relates to the technical field of temporomandibular joint dislocation treatment, in particular to a detachable elastic traction occlusal cushion and a manufacturing method thereof. Background technique [0002] The temporomandibular joint is mainly composed of the mandibular condyle, the temporal bone fossa, the articular disc, and the ligaments around the joint. During normal opening and closing movements, the condyle is restricted by the ligaments around the joint to avoid exceeding the normal range of motion. Damage to the articular ligament due to excessive opening for a long time or other reasons will cause the condyle to fail to return to the glenoid fossa after opening, resulting in dislocation of the temporomandibular joint. When dislocation of the temporomandibular joint occurs, the symptom is that the patient has a large opening The state cannot be closed, and it must be reset and treated by a doctor to return to normal.

AI Technical Summary

Problems solved by technology

The first is the extraoral bandage method. The patient needs to wear a bandage that wraps around the head and jaw to limit the excessive opening. Obviously, this method affects the patient's daily work and rest, and the bandage needs to be replaced regularly (several days) , is a traditional unsatisfactory treatment method; the second method is botulinum toxin injection, the principle of which is to inject a drug (botulinum toxin A) that can prevent or reduce the force of muscle contraction into the main chewing part of the opening movement The disadvantage of this method is that botulinum toxin A drug is toxic and can induce unpredictable complications such as anaphylactic shock; lateral pterygoid injection is a relatively Complicated clinical operations are prone to injection failures; the effect of botulinum toxin A has a certain time limit, and the drug effect only lasts for 2-3 months, and repeated injections may be required; the cost of drugs and injections is relatively high, and a clinical use The price of botulinum toxin A is around 1,000 yuan
