Functional appliance for correcting mandibular lordosis or mandibular retraction and manufacturing method thereof

Abstract

The invention discloses a functional appliance for correcting mandibular lordosis or mandibular retraction and a manufacturing method. The functional appliance is characterized in that: a maximum periodontal diameter line is coated, and a correction body is arranged; the correction body is provided with a correction block from the first premolar to the second premolar; the correction body is provided with a correction block from the second premolar or the second deciduous molar to the first permanent molar; the correction block is provided with an occlusal surface, the front end of the occlusal surface is an inclined surface, the rear end of the occlusal surface is a plywood, and the side surface of the occlusal surface is a coating surface; and the correction block is embedded with the corresponding plywood on the inclined surface. The upper module and the lower module of the appliance are embedded, so that the appliance worn by a patient can be freely matched and cannot be dislocated in the oral cavity function, the upper occlusion and the lower occlusion are effectively opened, the lower jaw can be guided to be backward or forward, and the appliance has a positive orthodontic effect on type-III malocclusion of mandibular lordosis and type-II malocclusion of mandibular retroduction in the growth and development period.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, in particular to a functional appliance for correcting mandibular protrusion or mandibular retrusion and a manufacturing method. Background technique [0002] Malocclusion is one of the diseases with a high incidence rate in humans. According to statistics, the incidence rate of orthodontics in developed countries in Europe and America is 85%, and the treatment rate is 75%. In my country, the incidence rate is 91.3%, but the treatment rate is less than 5%. The incidence rate of Angle class III malocclusion is about 12%, which ranks third in the occurrence of malocclusion. At present, the commonly used orthodontic methods for orthopedic functional Angle class III malocclusion include classic FR III appliance and Sander III appliance. Each of the above-mentioned appliances has indications and advantages and disadvantages. The FRⅢ type orthodontic wire for correcting functional class Ⅲ maloccl...

AI Technical Summary

Problems solved by technology

[0004] But the above-mentioned orthopedic class III and class II malocclusion functional appliances are all made of self-gel and benzene-containing monomers and handmade, which is complicated to make, has benzene-containing monomers and dust pollution, and costs high, while clinical class III and class II There are many patients with Class II malocclusion, and it is urgent to solve the above problems, and the functional appliance orthopedic treatment corrects bony deformities during the rapid growth and puberty period or the peak period, and will perform orthopedic intervention for marginal cases that may be expected to undergo surgery, blocking The further development of the deformity guides the reconstruction of the three-dimensional structure of the occlusion, jaw, and face to the normal type; changing the complex orthognathic surgery with severe skeletal deformity into a relatively simple operation after puberty orthopedic treatment is the basis of modern orthodontic theory
