摘　　要：目的:探讨外科导航系统结合CBCT在上颌前牙区完全骨埋伏多生牙拔除的临床应用意义。方法:纳入上颌前牙区完全骨埋伏额外牙患者40例,随机分为2组(n=20,每例患者1个患牙),实验组术中使用外科导航系统辅助定位并拔除患牙,对照组不使用外科导航系统进行手术,术前均拍摄CBCT影像。比较2组术中切口长度、显露患牙费时、手术时间、导航系统配准时间及术后并发症的发生情况。结果:实验组和对照组术中切口长度(cm)分别为3.14(3.00,3.26)和4.70(4.50,4.90)(Z=-5.46,P<0.001);显露患牙费时(min)为8.06±0.77和13.84±0.69(t=-25.11,P<0.001);手术时间(min)分别为43.50(39.25,51.50)和51.50(48.25,57.00)(Z=-3.43,P=0.001<0.05);疼痛NRS评分分别为2.00(1.00,2.75)和4.00(3.00,5.00)分(Z=-4.769,P<0.001)。2组患者未出现术中并发症,对照组术后局部肿胀5例。结论:外科导航系统辅助拔除上颌前牙区完全骨埋伏额外牙可缩短手术时间,减小翻瓣面积,降低术中及术后并发症。Objective:To investigate the clinical significance of surgical navigation system combined with CBCT in the extraction of completely introbony impacted supepenumerary teeth(IST)in maxillary anterior teeth.Methods:40 patients with IST(1 case with 1 IST)were included and divided into 2 groups(n=20).The surgical navigation system was used to assist positioning and extracting the affected IST during the operation in test group,but not in the control group.CBCT image was taken before all the operation.The intraoperative incision length,exposure time of the affected teeth,operation time,registration time of navigation system and postoperative complications were compared between the 2 groups.Results:In the test and control groups the incision length(cm)was 3.14(3.00,3.26)and 4.70(4.50,4.90)(Z=-5.46,P<0.001);the exposure time(min)of the affected teeth was 8.06±0.77 and 13.84±0.69(t=-25.11,P<0.001);the operation time(min)was 43.50(39.25,51.50)and 51.50(48.25,57.00)min(Z=-3.43,P=0.001<0.05);the pain NRS value was 2.00(1.00,2.75)and 4.00(3.00,5.00)(Z=-4.769,P<0.001),respectively.There was not complication in the test group.Postoperative local wound swelling was observed in 0 and 5 cases in the test and control groups respectively.Conclusion:The surgical navigation system can shorten the operation time,reduce the flap area and reduce the complications of the extraction of IST.
