Maxillary expansion type occlusal pad

Abstract

The invention discloses a maxillary expansion type occlusal pad used for mixed dentition condylar fracture. The maxillary expansion type occlusal pad comprises a base bracket, function surfaces, tissue surfaces, and a maxillary expansion device; the base bracket is used for coating upper dentition; the tissue surfaces on the upper part of the base bracket are fixedly arranged on oral cavity upperdental crowns of patients via bonding; the base bracket is divided into two parts, including an affected side base bracket and a healthy side bracket, at the center; the affected side base bracket andthe healthy side bracket are connected through the maxillary expansion device; the function surfaces on the lower part of the base bracket are designed to match mandibular teeth. The maxillary expansion type occlusal pad is used for correcting discordant maxilla and mandible width of children condylar fracture, and posterior crossbite, reducing the pressure of affected side condylar process zones, is excellent in matching relationship with canine fossa of antagonist teeth, and is capable of achieving preferable occlusion function recovery. The maxillary expansion type occlusal pad is reasonable in design, is convenient to use, is suitable for patients at deciduous dentition and / or mixed dentition, and especially suitable for patients at deciduous dentition.

Description

technical field [0001] The invention belongs to the field of oral medical devices, and more specifically relates to an arch-expanding occlusal pad for condyle fractures in the primary dentition stage. Background technique [0002] Among all mandibular fractures, the incidence of mandibular fractures in children is less than 15%; however, condylar fractures are common among children with mandibular fractures, accounting for 24%-72%. Children are in the growth and development stage, if the condyle fractures are not handled properly, it will lead to temporomandibular joint ankylosis and occlusal disorder, and even seriously affect the development of the mandible and maxillofacial region. At present, non-expanded common occlusal splints are widely used, and the equipment is simple and cheap, but the treatment is not personalized enough for different patients. After condyle fracture in children, the occlusal muscles pull the mandible and dentition on the affected side, which may...

AI Technical Summary

Problems solved by technology

When the patient chews, there is an occlusal movement, and the masticatory muscles are strong, which is more likely to cause dislocation of the occlusal pad
