摘　　要：目的:探究Nance托牵引装置联合外科导萌术对上颌埋伏尖牙患者术后肿胀、疼痛及并发症的影响。方法:纳入收治的105例上颌埋伏尖牙患者为研究对象,根据临床治疗方式不同分为对照组(n=52)和研究组(n=53)。对照组使用传统正畸固定矫正技术;研究组采取Nance托牵引装置联合外科导萌术。比较两组患者治疗成功率、埋伏牙萌出时间、术后肿胀程度、疼痛评分、细胞因子[基质金属蛋白酶3(MMP-3)、白细胞介素1β(IL-1β)]水平、口腔微环境差异;记录患者并发症发生情况。结果:研究组治疗成功率高于对照组(P<0.05);研究组埋伏牙萌出时间短于对照组(P<0.05);术后不同时间点,研究组术后肿胀程度及疼痛评分均低于对照组(P<0.05);治疗后,两组基质MMP-3、IL-1β、牙龈指数和菌斑指数均升高,且研究组低于对照组(P<0.05);研究组并发症总发生率低于对照组(P<0.05)。结论:使用Nance托牵引装置联合外科导萌术能够显著改善上颌埋伏尖牙患者术后肿胀程度,缓解其疼痛水平,并发症较低,安全性较好,具有良好的临床应用前景。Objective:To explore the influence of Nance traction device combined with edgewise technique on postoperative swelling,pain and complications in patients with maxillary impacted canines.Methods:105 patients with maxillary impacted canines were enrolled.By means of clinical treatment method,they were divided into control group(n=52)and study group(n=53).The control group used conventional orthodontic fixed correction technique and the study group adopted Nance traction device combined with edgewise technique.The differences in treatment success rate,impacted teeth eruption time,postoperative swelling degree,pain score,cytokines[matrix metalloproteinase-3(MMP-3),interleukin-1β(IL-1β)]and oral microenvironment were compared between the two groups,and the incidence rates of complications were recorded.Results:The success rate of treatment in study group was higher than that in control group(P<0.05).The eruption time of impacted teeth in study group was shorter than that in control group(P<0.05).At different time points after surgery,the postoperative swelling degree and pain score were lower in study group than those in control group(P<0.05).After treatment,the levels of MMP-3,IL-1β,gingival index(GI)and plaque index(PLI)were increased in both groups,and the study group had lower levels(P<0.05).The incidence rates of complications in study group were lower than those in control group(P<0.05).Conclusion:The application of Nance traction device combined with edgewise technique can significantly improve the postoperative swelling degree and relieve the pain level of patients with maxillary impacted canines,and it has few complications,good safety and good clinical application prospect.
