Abstract

The invention discloses an automatic stress applying functional correction device applied to upper jaw palate expansion. The correction device comprises a dental arch expander, wherein an expander body which is arranged at the position of the upper jaw is arranged in the center of the dental arch expander, bands are respectively connected to the two sides of the expander body through connection rods, two bands are arranged on the each side of the expander body, and the two bands are respectively used for sleeving a first premolar and a first molar. The correction device further comprises two base supporting plates which are used for being clamped to the left side and the right side of the upper jaw, wherein the appearance of the base supporting plates are adaptive to the shape of the upperjaw, the expander body is arranged between the two base supporting plates, and the left end and the right end of the expander body are partially embedded into the left base supporting plate and the right base supporting plate. The correction device further comprises two cheek screens which are used for being arranged on the outer sides of teeth on the left side and the right side, wherein the appearance of each cheek screen is adaptive to the shape of the outer side of the tooth tightly close to the cheek screen, and each cheek screen is connected to the base supporting plate adjacent to thecheek screen through a steel wire. Therefore, an unstable dental arch expanding effect in the prior art is overcome.

Description

【Technical field】 [0001] The invention belongs to the technical field of medical devices, and relates to an automatic force-applying functional correction device for maxillary and palate enlargement and a use method thereof. 【Background technique】 [0002] The incidence rate of malocclusion is as high as 78.89%, the harm is serious, and the course of treatment is long. The maxillary lateral hypoplasia mainly refers to the shortening of the lateral distance of the jaw in different degrees, accounting for 60-70% of malocclusions, and is the core key element of orthodontic diagnosis and treatment. It may cause tooth wear, occlusal interference, breathing disorder, facial aesthetics, increased incidence of TMD, CO-CR disorder, muscle dysfunction, and reduced mastication efficiency, often leading to vertical and sagittal abnormalities, which seriously damage the oral and maxillary system. Normal function and long-term stability, affecting the patient's facial aesthetics and phys...
