对于安氏Ⅲ类骨性病例,是否选择联合外科治疗,是获得成功的关键。矢状关系不调时,上下前牙可代偿性倾斜,建立正常的切牙关系。(牙合)平面的倾斜度也参与调节上下牙弓的关系。量化评价牙、牙槽对颌骨关系的补偿有助于安氏Ⅲ类错(牙合)成人患者治疗方案的设计。本研究的目的在于:①通过头影测量评价前牙
For Class III skeletal cases, the choice of joint surgery is the key to success. Sagittal relationship is not adjusted, the upper and lower anterior teeth can be compensated tilt, the establishment of normal incisor relationship. (Occlusal) plane inclination is also involved in regulating the relationship between the upper and lower arch. Quantitative evaluation of the teeth, alveolar compensation for the relationship between the jaw contribute to the treatment of Class Ⅲ malocclusion patients with adult treatment design. The purpose of this study is to: (1) evaluate the anterior teeth by cephalometric measurements
