A type III personalized functional appliance

Abstract

The invention discloses an III type appliance with a personalized function as well as a manufacture method and an application of the III type appliance. The III type appliance with the personalized function comprises a maxillary outer side base 1, a maxillary tongue side base 2, an occlusal pad 3, a mandible outer side base 4 and a mandible tongue side base 5, wherein the maxillary outer side base 1 and the maxillary tongue side base 2 are integrally connected through the occlusal pad 3 to form an upper tooth space 6, and the mandible outer side base 4 and the mandible tongue side base 5 are integrally connected through the occlusal pad 3 to form a lower tooth space 7. The III type appliance with the personalized function can promote growth of maxilla and inhibit growth of mandible, and the purpose of preventive or interruptive correction of functional III type malocclusion or mild bony III type malocclusion is achieved; correction is completed under the condition that tooth extraction for subtrahend is not adopted, the conditions that the front section of the upper dental arch becomes narrower and the side face of the upper dental arch is more umbilicate can be avoided, reverse occlusion of anterior teeth can be corrected, space is regained, dentition is aligned, the face shape is improved, and the III type appliance with the personalized function has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of oral medical instruments. More specifically, it relates to a type III personalized functional appliance and its manufacturing method and application. Background technique [0002] Functional class III malocclusion, also known as pseudo-III sexual malocclusion, is a type of Angle's class III malocclusion. Angle's class III malocclusion is a relatively common clinical oral malformation, which can be divided into false class III malocclusion, dental class III malocclusion, and skeletal class III malocclusion. Pseudo-III malocclusion, also known as functional Class III malocclusion, is caused by the labial inclination of the mandibular anterior teeth, or the lingual inclination of the maxillary anterior teeth, or a combination of the two, or the interference of individual teeth, forcing the mandible to move forward Position, resulting in anterior crossbite, molars in a class III occlusal relationship, norma...

AI Technical Summary

Problems solved by technology

However, the front traction correction method has the following defects: (1) as an extraoral device, the front traction needs to be worn for more than 14 hours a day, and the comfort is poor; (2) the treatment time is long; (3) the front traction requires regular replacement of the rubber band, and it cannot be used when going out. It can only be worn at home, so it requires a relatively high degree of cooperation from the patient; (4) The existence of the traction device will cause certain safety hazards

[0004] Although compared with the frontal traction correction method, the labial bow expansion movable correction method uses intraoral appliances, which has the advantages of shorter correction time, relatively better comfort, and higher patient cooperation, but still has the following defects: (1) multi-purpose For dental deformities, it has poor effect on functional or mild bone; (2) It does not have the effect of promoting the growth of the maxilla and inhibiting the growth of the mandible; (3) It needs to be worn for 24 hours, including diet, etc.
