A type II personalized functional appliance and its manufacturing method and application

Abstract

The invention discloses an II type appliance with a personalized function as well as a manufacture method and an application of the II type appliance. The II 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 II type appliance with the personalized function can promote growth of mandible and inhibit growth of maxilla, and the purpose of preventive or interruptive correction of functional II type malocclusion or mild bony II 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 II 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 II personalized functional appliance and its manufacturing method and application. Background technique [0002] Angle's class II malocclusion is a relatively common clinical oral malformation, which can be divided into pseudo II malocclusion, dental II malocclusion, and skeletal II malocclusion. Pseudo-Ⅱ malocclusion, also known as functional Class-Ⅱ malocclusion, can force the mandible to move backward due to the interference of individual teeth, resulting in deep coverage of the anterior teeth, molars in Class-Ⅱ occlusal relationship, and the size of the upper and lower jaws is normal. The lower jaw is functionally displaced. The skeletal type II malocclusion is often accompanied by abnormal size and development of the mandible. Dental class II malocclusions are mostly caused by abnormal inclination of the teeth, and good results can ...

Problems solved by technology

However, the headgear-muscle activator has the following disadvantages: (1) the comfort of the headgear-muscle activator is poor; (2) it is often necessary to wear a headgear, which is unsightly; (3) it is impossible to align teeth while correcting bony problems ; (4) The existence of the traction device will cause certain safety hazards

[0004] Although compared with the twinblock appliance, the twinblock appliance uses an intraoral appliance, which has the advantages of shorter treatment time, relatively better comfort, and higher patient cooperation, but still has the following defects: (1) It cannot be used in the treatment of bone The problem is to align the teeth at the same time; (2) It does not have the function of oral function training, etc.
