目的探讨轻度骨性Ⅱ类错畸形患者经上颌前牙牙槽骨骨皮质切开辅助治疗后的临床效果。方法选取2014年6月~2016年6月在我院就诊的6例轻度骨性Ⅱ类错畸形患者,均实施上颌前牙牙槽骨骨皮质切开辅助治疗,记录每名患者的矫治疗程及实施骨皮质切开术后前牙内收时间,在治疗前后对所有研究对象进行CBCT的拍摄,根据CBCT获取的数据进行三维测量分析。结果 6名轻度骨性Ⅱ类错畸形患者经上颌前牙牙槽骨骨皮质切开辅助治疗后获得了较为显著的治疗效果,术后矫治疗程19~26周,平均值(23.75±5.32)周;术后前牙内收至正常位置的时间3~4周,平均值(3.24±0.76)周。经治疗后,轻度骨性Ⅱ类错畸形患者软组织及硬组织指标情况较治疗前有了显著的改善,实现了患者前牙的整体内收,治疗前与治疗后相比,差异具有统计学意义(P<0.05)。结论轻度骨性Ⅱ类错畸形患者采用上颌前牙牙槽骨骨皮质切开辅助治疗后,有效缩短患者矫治疗程及术后前牙内收至正常位置的时间,实现了患者前牙的整体内收,患者软组织侧貌得以改善,颜面部整体形态美观度明显增强。
Objective To investigate the clinical effect of the treatment of mild skeletal class Ⅱ malocclusion by maxillary anterior alveolar bone cortical osteotomy. Methods Six patients with mild skeletal class Ⅱ malocclusion treated in our hospital from June 2014 to June 2016 were enrolled in the treatment of maxillary anterior alveolar bone cortical osteotomy and the treatment of each patient was recorded CBCT was performed on all subjects before and after treatment, and three-dimensional measurements were made according to the data obtained by CBCT. Results Six patients with mild skeletal Class Ⅱ malocclusion had a significant therapeutic effect after anterior maxillary anterior alveolar bone cortical osteotomy. The postoperative treatment ranged from 19 to 26 weeks (mean, 23.75 ± 5.32) Weeks; postoperative anterior teeth received normal position for 3 to 4 weeks, mean (3.24 ± 0.76) weeks. After treatment, mild skeletal Class Ⅱ malocclusion deformity patients with soft tissue and hard tissue index than before treatment has been significantly improved to achieve the overall adduction of patients with adduction before treatment compared with after treatment, the difference was statistically Significance (P <0.05). Conclusions The patients with mild skeletal class Ⅱ malocclusion have the advantages of using maxillary anterior alveolar bone cortical osteotomy to shorten the duration of orthodontic treatment and postoperative anterior closing to the normal position, Admitted, the patient’s soft tissue profile can be improved, the facial appearance of the overall shape of the aesthetics was significantly enhanced.
