摘　　要：目的 探讨与研究成人安氏Ⅱ类Ⅰ分类错[牙合]畸形(AngleⅡ)治疗前后髁突形态、上尖牙牙槽骨形态变化情况。方法选择2021年8月至2023年12月在焦作市人民医院进行治疗的安氏Ⅱ类Ⅰ分类错[牙合]畸形成人患者62例作为研究对象。所有患者都给予扩弓矫治,治疗观察时间为6个月,记录髁突形态、上尖牙牙槽骨形态变化情况。结果 62例患者治疗6个月后的ANB、SNA、SNB、Sn-H、LL-E等髁突形态参数降低,与治疗前相比差异有统计学意义(P<0.05),LL-H明显提高,与治疗前相比差异有统计学意义(P<0.05)。治疗6个月后的磨牙移位距离显著降低,中切牙倾角差、上中切牙凸距与治疗前显著提高,与治疗前相比差异有统计学意义(P<0.05)。治疗6个月期间发生并发症8例,发生率为12.90%,其中龋齿5例、口腔黏膜损伤1例、食物嵌塞1例、牙周炎1例。治疗6个月后的固定性、美观度、舒适度、咀嚼功能等口腔功能评分都显著高于治疗前,差异有统计学意义(P<0.05)。结论 成人安氏Ⅱ类Ⅰ分类错[牙合]畸形治疗前后髁突、上尖牙牙槽骨会发生明显的形态变化,可显著提高患者的口腔功能。Objective To explore and study the changes in condylar and upper canine alveolar bone morphologies before and after treatment in adult patients with angle class II division malocclusion Division 1.Methods Sixty-two adult patients with Class II,Division I malocclusion who received treatment at Jiaozuo People's Hospital from August 2021 to December 2023 were selected as the study subjects.All patients received arch expansion orthodontic treatment,with a treatment observation period of 6 months.The changes in condyle morphology and alveolar bone morphology of the upper canine were recorded.Results After 6 months of treatment,the morphological parameters of the condyle,including ANB,SNA,SNB,Sn-H,and LL-E,in 62 patients decreased significantly compared to before treatment(P<0.05),while LL-H increased significantly compared to before treatment(P<0.05).After 6 months of treatment,the displacement distance of molars significantly decreased,and the inclination angle difference of the central incisors and the protrusion distance of the upper central incisors significantly increased compared to before treatment,with statistical significance(P<0.05).During the 6-month treatment period,8 cases of complications occurred,with an incidence rate of 12.90%,including 5 cases of dental caries,1 case of oral mucosal injury,1 case of food impaction,and 1 case of periodontitis.After 6 months of treatment,the oral function scores such as fixation,aesthetics,comfort,and chewing function were significantly higher than before treatment,and the difference was statistically significant(P<0.05).Conclusions Before and after treatment for adult angle class II division malocclusion Division 1,there will be significant morphological changes in the condyle and maxillary alveolar bone,which can significantly improve the oral function of patients.
