Integral-type initiative oral cavity mouth gag

Abstract

The invention discloses an integral-type initiative oral-cavity mouth gag, which comprises horseshoe-shaped upper jaw plate and a lower jaw plate which conform to an upper dental arch and a lower dental arch, wherein a torsion spring is arranged between the upper and the lower jaw plates, when the spring is free from additional pinching force, the tension of the spring facilitates the formation of an angle between the upper and the lower jaw plates, and the upper and the lower jaw plates are connected with each other through a rear end connection steel wire; when in wearing, the upper and thelower jaw plates are closed, so the upper and the lower jaw plates are arranged between occlusal surfaces of upper teeth and lower teeth, and after the upper and the lower jaw plates are released, the spring is rebounded, so a continuous opening force can be supplied. The integral-type initiative oral cavity mouth gap has the advantages that: the size is small, the wearing is convenient, the operation is simple, the wearing is reflected by clinical test patient to be more comfortable that of a passive mouth gag, when wearing the mouth gag, the lower jaw can make the mouth closing movement, sothe function of masticatory muscles can be effectively exercised, and the mouth gag can be used for the computer aid design of the jaw face part individualized repair body.

Description

technical field [0001] The mouth gag designed by the present invention is mainly used for training and helping patients to open their mouths. It is mainly suitable for conservative treatment of temporomandibular joint injuries caused by trauma or postoperative mouth opening training. It is also suitable for mouth opening caused by spasm of masticatory muscles caused by various reasons. Difficult, and can be used for computer-aided design of individualized restorations in the maxillofacial region. Background technique [0002] Most of the mouth gags used clinically are passive gags used on one side or both sides. The principle of action is wedging to lower the jaw to open the mouth. The patient or doctor wedges the gag to make the patient's mouth open in a fixed position. , the mandible cannot close the mouth after the patient opens the mouth; the advantage of this type of mouth gag is that it is easy to manufacture; the disadvantages are: 1. It is relatively complicated to o...

Problems solved by technology

[0002] Most of the mouth gags used clinically are passive gags used on one side or both sides. The principle of action is wedging to lower the jaw to open the mouth. The patient or doctor wedges the gag to make the patient's mouth open in a fixed position. , the mandible cannot close the mouth after the patient opens the mouth; the advantage of this type of mouth gag is that it is easy to manufacture; the disadvantages are: 1. It is relatively complicated to operate by continuously increasing the wedge or increasing the wedge force during use; 2. The mandible cannot be closed after the patient opens the mouth. If you do the mouth-closing exercise again, the masticatory muscles cannot be effectively trained, the function of the masticatory muscles will not recover well, and the degree of mouth opening formed is difficult to maintain
