摘要:
安氏Ⅱ类2分类患者口内表现为前牙内倾，覆牙合较深，通常侧貌较佳，故在正畸治疗时，期望改变切牙轴向，打开咬 合，恢复前牙正常覆牙合覆盖，但尽可能不破坏软组织侧貌。该类患者由于上切牙舌向倾斜，常常导致上前牙牙根紧贴唇侧骨 皮质，造成牙根及牙槽骨形态改变，而受遗传、环境等因素的影响，患者的牙体发育时也会有不同于其他错牙合畸形患者的特 点，这些因素均会对牙的移动以及牙槽骨的改建造成影响。因此，在正畸治疗前后，均应了解并关注这类患者上前牙区牙及 牙槽骨的形态及变化，控制牙体进行安全有效的移动。
Abstract:
In patients with Class Ⅱ Division 2, the oral manifestations of the anterior teeth are inverted and the overbite is deep, but the patient usually has a better profi le. Therefore, during orthodontic treatment, it is expected to change the incisor axis, open the occlusion, and restore the normal overbite of the anterior teeth. Occlusion covers, but as far as possible not to damage the soft tissue profi le. Due to the inclination of the tongue of the upper incisor, the roots of the upper anterior teeth often adhere to the labial cortex, causing changes in the morphology of the roots and alveolar bone. Aff ected by genetic and environmental factors, the patient’s teeth develop There are characteristics that are diff erent from other malocclusion patients. These factors will aff ect the movement of teeth and the reconstruction of the alveolar bone. Before and after orthodontic treatment, you should understand and pay attention to the teeth and the upper anterior teeth of such patients. The shape and change of the alveolar bone can control the tooth to move safely and eff ectively.
