安氏Ⅱ类1分类错颌畸形患者和安氏Ⅱ类2分类错颌畸形患者进行检查，其牙槽

Angle class Ⅱ 1 malocclusion and jaw deformity patients Angle Class Ⅱ 2 malocclusion deformity patient examination, there is a relationship which alveolar tooth position, tooth movement can not be used without bone compensatory adjustment situation, preventing tooth inappropriate shift occurs root resorption, decreased alveolar bone density, where bone perforation.

Anshi II Class 1 classified wrong jaw malformation patients and Anshi II Class 2 classified wrong jaw malformation patients to check, its tooth groove bone shape and tooth position there is a certain relationship, can not use dental mobile compensation bone incongruity, to prevent tooth shift inappropriate tooth root absorption, tooth groove bone density reduction, bone perforation and so on.

The alveolar bone morphology of patients with class II 1 malocclusion and class II 2 malocclusion was related to the position of teeth. It was not allowed to use tooth movement to compensate for bone disorder, so as to prevent improper root resorption, low alveolar bone density and bone perforation.<br>
