目的分析前牙区牙槽骨骨裂孔现象及对正畸治疗的影响。方法对30例正常及90例骨性错畸形患者进行锥形束(CBCT)扫描,并对相关数据进行分析。结果骨裂孔多发于下颌,侧切牙最为常见,整体发病率以骨性Ⅱ类错畸形最高,骨性Ⅲ类错畸形最低;骨性Ⅰ类错畸形和正常间差异无统计学意义。结论正畸治疗时应重视骨裂孔所带来的影响。 Objective To analyze the alveolar fracture of anterior teeth and its effect on orthodontic treatment. Methods 30 cases of normal and 90 cases of skeletal malformation deformity cone beam (CBCT) scan, and the relevant data were analyzed. Results The fissures were found in the lower jaw and the lateral incisors were the most common. The overall incidence was the highest in type II malocclusion and the lowest in type Ⅲ malocclusion. No significant difference was found between the type Ⅰ malocclusion and the normal type. Conclusion Orthodontic treatment should pay attention to the impact of osteoporosis.
