The incidence rate of Angle III type malocclusion is about 12 percent, which is the third occurrence of malocclusion, and the current common orthodontic methods for correcting functional Angle III type malocclusion are a classic FR III type appliance, a SanderIII appliance and the like. The appliance has indications and advantages and disadvantages. The FR III type correcting steel wire for correcting functional III type malocclusion is complicated in bending, large in size, language dysfunction and uncomfortable to wear; the sanderi appliance is cumbersome to manufacture and expensive.
The type II malocclusion is the second place among malocclusion malformative patients, and the prevalence rate of the type II malocclusion substituting tooth of Chinese people is 25.77% and the prevalence rate of the type II malocclusion substituting tooth of permanent teeth is about 19.41% in 2000 by the Fouwolfi. Wherein the single factor of Chinese Anshi II 1 type malocclusion is that the retroreduction of the jaw is mainly 49%, the upper jaw position is 62% for normal people, and the position is 38% for abnormal people. The treatment method mainly comprises the functions of orthopedic treatment of the orthodontic device, fixed orthopedic treatment of the orthodontic device and orthognathic operation treatment. The type II malocclusion mechanism is characterized by retrognation mainly and vertical dysplasia. The existing functional appliance orthopedic treatment mandibular advancement guiding functional appliance methods comprise a muscle Activator (Activator), a biological regulator (bionator), a function regulator (Frankel function regulator), a push rod type mandibular advancement guiding functional appliance (Herbst, Jasper Jumper, Forsus), a Headgear type muscle Activator (Headgear Activator), a mandibular advancement guiding functional appliance (Twin-Block), Sander II (SII) and the like, and are different in adaptation diseases.
