A kind of appliance for correcting open bite deformity, preparation method and application thereof

Abstract

The invention discloses an appliance for correcting open bit malformation and a preparation method and application. The appliance comprises a base support, wherein the base support is a base manufactured according to the shape of an upper jaw and / or a lower jaw of a human mouth; the base at least comprises an adhesion surface of the upper jaw and / or the lower jaw, and a smooth surface contacting atongue periphery; molar tooth occlusal surface supports are fixedly arranged on the base support; the molar tooth occlusal surface supports are at least arranged in positions of front molar teeth and / or molar teeth; fixing clamping parts are fixedly arranged on the base support; the fixing clamping parts are clamped at tooth peripheries and / or adjacent tooth gaps; particularly, when the base support is a low jaw base support, tongue rising bulges are arranged in positions from the front molar teeth to the molar teeth on the base support; the tongue rising bulges are used for rising a tongue.By adopting the appliance disclosed by the invention, the blank of intraoral appliances for correcting open bit malformation or type III or type II malocclusion caused by bad tongue habits can be madeup, the clinical treatment rate can be increased, meanwhile reoccurrence of open bit malformation can be prevented, and the clinical treatment rate is 100%.

Description

technical field [0001] The invention belongs to the field of orthodontic aids, in particular to an appliance for correcting open bite deformity, a preparation method and an application thereof. Background technique [0002] The term "openbite" was coined by Caravelli in 1842 and the prevalence ranges from 1.5% to 11% of the population. Prevalence decreases due to sucking habit and oral function matures with age. At age 6, the prevalence was 4.2%, with AOB, and at age 14 the prevalence decreased to 2%. (Artese et al, 2011). Evolutionary factors and environmental factors are the causes of opening and closing. The adroitness factors include the position, shape and size of the tongue; the growth type of the upper and lower jaws, especially the mandible, and the vertical relationship between the upper and lower jaw bones. Among the environmental factors, the infantile type Swallowing, nasopharyngeal abnormalities, mouth breathing with hypertrophic adenoids, finger sucking, exc...

AI Technical Summary

Problems solved by technology

[0003] The existing treatment methods include functional orthopedic buccal screen appliances, tongue spur appliances, natural TE appliance, chewing gum training tongue muscle method, fixed appliance and extramaxillary surgery, but the blocking correction buccal screen appliance, Depressed molar splint type appliances, fixed appliances such as multi-curved arches, and surgical treatment have not been corrected from the cause of tongue protruding and bottom tongue habit, resulting in high clinical recurrence rate and poor long-term effect; compared with the existing palatal spur appliance only It is used to block tongue extension without tongue muscle training and lower molar effect; compared with the existing method of using chewing gum to train the tongue muscle in the front of the mouth and palate, the tongue muscle is prone to fatigue, and the patient's training compliance is uncertain, and the curative effect is uncertain.
