Abstract
BACKGROUND: Skeletal class Ⅲ malocclusion is a complex malocclusion in clinic, which has a great harm to the development of teeth, maxil a and face. Currently, skeletal class Ⅰ malocclusion is often explored in the self-ligating system, and there is yet no reports addressing self-ligating system for treatment of skeletal class Ⅲmalocclusion. OBJECTIVE: To analyze the results of X-ray lateral cephalometric radiographs and model measurement before and after Clippy self-ligating system treatment of mild and moderate class Ⅲ malocclusion so as to determine the therapeutic effect of Clippy self-ligating system. METHODS: Thirty-four patients with skeletal class Hospital Group, aged 11-15 years (averagely 12.8 years), including 21 males and 13 females. The angle of ANB (subspinale, Nasion, supramental) was -2.1° on average. Al the patients were treated with Clippy self-ligating system, and maxil ary expansion and rapid palatal expansion appliance and auxiliary rehabilitation measures were performed during the treatment. The average course of treatment was 23.7 months. X-ray lateral cephalometric radiographs were shot to measure the relevant data. RESULTS AND CONCLUSION: (1) After treatment, the teeth of the 34 patients arranged regularly, normal jet and bite was established, and the maxil ary and madibuar first molar relationship reached a neutral or slightly mesial relation. (2) The ANB angle was increased by 1.56° and the anterposterior dysplasia indicator decreased by -2.22°. Malocclusion reverted from class Ⅲ to class horizontal width of the maxil ary and mandibular dental arch was expanded, and the sagittal length of the maxil ary adental arch was increased. The Clippy self-ligating system is able to successful y col ect mild to moderate skeletal class soft tissue profile, expands the horizontal width of the maxil ary and mandibular dental arch and increases the sagittal length of the maxil ary arch.关键词
