Orthosis

Abstract

The invention belongs to the technical field of orthodontics, and particularly relates to an orthosis. The orthosis comprises a U-shaped jaw pad, a lip screen and a tongue screen, wherein the lip screen and the tongue screen are arranged on and under the U-shaped jaw pad separately. The lower end of the lip screen is connected with the outer side edge of the U-shaped jaw pad, the upper end of thetongue screen is connected with the inner side edge of the U-shaped jaw pad, and the lower end of the tongue screen extends towards the opening direction of the U-shaped jaw pad. The invention belongsto the category of functional orthoses, and a patient can freely remove and wear the orthosis without a metal fixation device which is prone to bring stabbing pain to the patient, so that wearing iscomfortable; and the same time, the orthosis is preformed in a certain size without ordering, so that the price is lower.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to an orthodontic appliance. Background technique [0002] Class III malocclusion (commonly known as underbite) is a serious oral and jaw deformity and facial deformity, that is, the relationship between the mandibular and mandibular molars and the maxillary molars is protruding. The imbalance of muscle strength around the oral cavity is an important reason for Class III malocclusion. From the front-to-back perspective, the strength of the upper lip muscles in Class III malocclusion is too strong, which inhibits the forward growth of the upper jaw; the muscle strength of the lower lip is insufficient, which cannot restrain the forward jaw. grow. The tongue that should be on the lingual side of the upper anterior teeth is located on the lingual side of the lower anterior teeth, which is often referred to as the low tongue. The low-lying tongue cannot give the upper...

Problems solved by technology

The retaining device of the removable appliance is easy to sting the patient. The functional appliance is huge in size and uncomfortable to wear, and the patient’s compliance is not high. At the same time, the appliance needs to be customized, which is expensive and complicated to use, so it is not suitable for general dentists.

[0004] Patent No. CN200880103923.2 discloses an orthodontic appliance, which is made of materials such as silica gel that allows elastic deformation, and includes a mounting device, an outer spacer forming part and a tongue lifting forming part; Class II or Class III malocclusion patients can Correction is carried out by wearing the orthodontic appliance inside the oral cavity, but the orthodontic appliance includes many parts and has a very complicated structure, resulting in high manufacturing costs and poor economic efficiency
