摘　　要：目的分析替牙期含牙囊肿内埋伏上颌中切牙开窗配合正畸牵引术对患儿牙根发育的影响。方法回顾性分析2016年11月至2021年11月宁德师范学院附属宁德市医院口腔科收治的48例替牙期含牙囊肿内埋伏上颌中切牙患儿资料,按手术方法分为对照组(44颗患牙,标准方丝弓技术矫正)和观察组(46颗患牙,开窗配合正畸牵引术)。比较两组治疗前后牙根长度和根管壁厚度;比较两组治疗后唇腭侧牙槽骨水平和厚度。结果治疗后,两组牙根长度和根管壁厚度大于治疗前,且观察组大于对照组,差异有统计学意义(P<0.05)。两组腭侧牙槽骨水平和厚度比较,差异无统计学意义(P>0.05);观察组唇侧牙槽骨水平和厚度小于对照组,差异有统计学意义(P<0.05)。结论开窗配合正畸牵引术可促进替牙期含牙囊肿内埋伏上颌中切牙患者牙根和根管壁正常发育。Objective To analyze the effect of fenestration combined with orthodontic traction on the root growth child patients with maxillary central incisor embedded in dental cysts of replacement stage.Methods Retrospective analysis was performed on the data of 48 child patients with maxillary central incisor embedded in dental cysts of replacement stage admitted to Department of Stomatology,Ningde Municipal Hospital of Ningde Normal University from November 2016 to November 2021.According to the surgical methods,they were divided into control group(44 affected teeth,standard square wire bow technique correction)and observation group(46 affected teeth,fenestration combined with orthodontic traction).The root length and root canal wall thickness of two groups were compared before and after treatment;the level and thickness of labial-palatal alveolar bone were compared between two groups after treatment.Results After treatment,the root length and root canal wall thickness of two groups were greater than those before treatment,and observation group was greater than control group,and the differences were statistically significant(P<0.05).There was no significant difference in the level and thickness of palatal alveolar bone between two groups(P>0.05);the level and thickness of labial alveolar bone in observation group were less than those in control group,and the differences were statistically significant(P<0.05).Conclusion Fenestration combined with orthodontic traction can promote the normal development of root and canal wall in patients with maxillary central incisor embedded in dental cysts of replacement stage.
