摘要
目的探讨锥形束CT定位联合鼻底入路涡轮反角手机去骨法在上颌正中高位埋伏多生牙中的应用效果。方法选取2020年1月至2022年1月安徽省儿童医院收治的78例上颌正中高位埋伏多生牙患者,采用随机数字表法分为观察组和对照组。2组患者均行锥形束CT定位检查,对照组采用腭侧入路或唇侧入路涡轮反角手机去骨法拔牙(根据多生牙整体位于临近切牙的腭侧或唇侧决定),观察组采用鼻底入路涡轮反角手机去骨法拔牙。比较2组患者手术时间、术中出血量,术后视觉模拟疼痛评分(VAS)、牙齿咬合力、咀嚼效率以及并发症发生情况。结果观察组手术时间[腭侧(21.57±3.31)min;唇侧(22.82±3.53)min]短于对照组[腭侧(36.44±6.39)min;唇侧(39.25±6.78)min](均P<0.05),术中出血量[腭侧(14.37±2.42)ml;唇侧(15.64±2.67)ml]少于对照组[腭侧(19.56±3.18)ml;唇侧(21.89±3.55)ml](均P<0.05);术后VAS评分[腭侧(2.87±0.42)分;唇侧(3.14±0.49)分]低于对照组[腭侧(4.75±0.67)分;唇侧(5.06±0.83)分](均P<0.05);手术后两组牙齿咬合力和咀嚼效率较手术前均升高(均P<0.05),且观察组牙齿咬合力[腭侧(148.49±22.35)Ibs;唇侧(144.92±21.68)Ibs]和咀嚼效率[腭侧(92.66±16.22)%;唇侧(90.83±15.94)%]均高于对照组[牙齿咬合力:腭侧(121.27±19.81)Ibs;唇侧(118.74±18.85)Ibs;咀嚼效率:腭侧(83.47±13.76)%,唇侧(79.79±13.02)%](P<0.05);2组患者并发症发生率比较差异无统计学意义(P>0.05)。结论锥形束CT定位联合鼻底入路涡轮反角手机去骨法用于上颌正中高位埋伏多生牙患者,能够缩短手术时间,减少出血量,术后疼痛程度轻,舒适度更高,安全可靠。
Objective To investigate the application effect of cone-beam computed tomography(CT)positioning combined with nasal bottom approach turbo contra-angle handpiece bone removal method in maxillary mid-high impacted supernumerary teeth.Methods A total of 78 patients with supernumerary teeth in the middle and high position of the maxilla who were admitted to Anhui Children′s Hospital from January 2020 to January 2022 were selected and divided into the observation group and the control group according to the random number table method.The patients in both groups underwent cone-beam CT localization examination.The control group used the palatal approach or the labial approach to remove the bone with the turbo contra-angle handpiece(depending on whether the supernumerary teeth were located in the palatal or labial side adjacent to the incisor as a whole),and the observation group used the nasal approach to remove the bone with the turbo contra-angle handpiece.The operation time,intraoperative blood loss,postoperative Visual Analogue Scale(VAS),occlusal force,masticatory efficiency and complications were compared between the two groups.Results The operation time in the observation group[palatal side(21.57±3.31)min;labial side(22.82±3.53)min]was shorter than that in the control group[palatal side(36.44±6.39)min;labial side(39.25±6.78)min](P<0.05),and the intraoperative blood loss[palatal(14.37±2.42)ml;labial(15.64±2.67)ml]was less than that in the control group[palatal side(19.56±3.18)ml;labial side(21.89±3.55)ml](P<0.05).The postoperative VAS score of the observation group[palatal(2.87±0.42)points;labial(3.14±0.49)points]was lower than that of the control group[palatal side(4.75±0.67)points;labial side(5.06±0.83)points](all P<0.05).After operation,the occlusal force and masticatory efficiency in the two groups were higher than those before the operation(all P<0.05),and the occlusal force[palatal(148.49±22.35)Ibs;labial(144.92±21.68)Ibs]and masticatory efficiency[palatal side(92.66±16.22)%;labial side(90.8
