Forward mandibular positioning device for orthodontics

Abstract

The invention provides a forward mandibular positioning device for orthodontics. The forward mandibular positioning device for orthodontics comprises an upper appliance, a lower appliance, upper forward positioning force-augmentation parts and lower forward positioning force-augmentation parts; the upper appliance comprises upper retention parts, which are arranged on at least one molar tooth of teeth at two sides of the upper jaw in a sleeving manner; the upper retention parts at two sides are connected through an upper jaw connection part; the lower appliance comprises lower retention parts,which are arranged on at least one molar tooth of teeth at two sides of the lower jaw in a sleeving manner; the lower retention parts at two sides are connected through a lower jaw connection part; the upper forward positioning force-augmentation parts are fixed on the outer side surfaces of the upper retention parts; the lower forward positioning force-augmentation parts are fixed on the outer side surfaces of the lower retention parts; the surface of the front part of each upper forward positioning force-augmentation part is provided with an inclined surface; the inclined surfaces are guideinclined surfaces of the forward mandibular positioning device; and the lower forward positioning force-augmentation parts perform reciprocating rolling / sliding on the inclined surfaces, so that theforward mandibular positioning effect is achieved. The forward mandibular positioning device in the invention is fixedly installed on the teeth at the back of the upper and lower jaws; and thus, forward mandibular positioning and correction of upper and lower anterior teeth can be synchronously carried out.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to a mandibular leading device for orthodontics. Background technique [0002] Malocclusion refers to the deformity of teeth, jaw, and craniofacial caused by congenital or acquired factors during the growth and development of children. The main manifestations are irregular dentition, misalignment of the upper and lower jaws, such as buck teeth and teeth. Malocclusion is listed as the three common diseases of the oral cavity together with caries and periodontal disease, and its prevalence rate is as high as more than 50% of the population. Mandibular retrusion is the most common type of mandibular dislocation, and it is often corrected with removable mandibular protruding devices. [0003] The current mandibular leading device and other orthodontic appliances are independent individuals. Usually, patients need to undergo the second stage of orthodontic treatment after the mandibular lea...

AI Technical Summary

Problems solved by technology

[0003] The current mandibular leading device and other orthodontic appliances are independent individuals. Usually, patients need to undergo the second stage of orthodontic treatment after the mandibular leading treatment. They need to wear the mandibular leading device and the orthodontic appliance separately. longer

[0004] In addition, at present, the mandibular leading device mostly uses the inclined plane guidance located on the occlusal surface, the rigid sleeve structure support or the movable protruding induction structure. The structure is relatively complex, the volume is large, and the wearing comfort is poor.
