摘　　要：目的探讨牙根不同发育状态下闭合式开窗导萌术联合正畸牵引治疗对上颌埋伏阻生前牙的临床治疗效果。方法选取2021年1月~2022年1月该院收治并经闭合式开窗导萌术联合正畸牵引治疗的上颌埋伏阻生前牙84例作为研究对象,根据牙根发育状态分为完全组(牙根发育完全)、未完全组(牙根发育不完全),记录两组患者治疗时间,比较两组患者而治疗疗效、恢复情况、并发症发生情况。结果未完全组患者临床治疗总有效率为97.62%高于完全组的85.71%,差异有统计学意义(P<0.05);未完全组患者治疗时间、牙龈指数、出血指数低于完全组,咬合力、咀嚼效率明显高于完全组,差异有统计学意义(P<0.05);未完全组并发生症总发生率为4.76%明显低于完全组的19.05%(χ^(2)=4.086,P=0.043)。结论牙根发育不完全患者采用闭合式开窗导萌术联合正畸牵引治疗效果优于牙根发育完全患者,且并发症少。Objective To explore the clinical effect of closed guide eruption combined with orthodontic traction in treatment of impacted anterior maxillary teeth under different root development status.Methods During the period from January 2021 to January 202284 patients with impacted anterior maxillary teeth who underwent closed guide eruption combined with orthodontic traction and were admitted to the hospital were enrolled as research objects.According to different root development status,they were divided into complete group(complete root development)and incomplete group(incomplete root development).The treatment time in both groups was recorded.The curative effect,recovery and complications were compared between the two groups.Results The total response rate of clinical treatment in incomplete group was higher than that in complete group(97.62%vs 85.71%)(P<0.05).The treatment time,gingival index and bleeding index in incomplete group were lower than those in complete group,while occlusion force and chewing efficiency were significantly higher than those in complete group(P<0.05).The total incidence of complications in incomplete group was significantly lower than that in complete group(4.76%vs 19.05%)(χ^(2)=4.086,P=0.043).Conclusion The curative effect of closed guide eruption combined with orthodontic traction is better on patients with incomplete root development than that on patients with complete root development,with fewer complications.
