摘　　要：目的:探究双波长激光结合数字化导板应用于上颌埋伏中切牙牵引中的临床疗效。方法:收集2020年6月~2022年6月就诊于合肥市口腔医院西区儿童口腔科的上颌中切牙埋伏阻生的患儿共20例,年龄7~10岁。随机分为激光导板组和传统手术组,分别记录两组手术时长、术中出血量和疼痛视觉模拟评分(VAS)值,以及在术后第1天、第3天、第7天记录两组VAS值和术后第1个月、第2个月和第3个月记录托槽的脱落率。结果:激光导板组术中出血量少于传统手术组;激光导板组的平均手术时间为(22.4±5.9)min,传统手术组的平均手术时间是(44.0±16.8)min;在术后第1天和术后第3天激光导板组在较低VAS评分等级中的人数低于传统手术组,差异均有统计学意义(P<0.05);而两组在术中和术后第7天的VAS评分等级及术后1个月、2个月和3个月托槽脱落率的比较差异无统计学意义(P>0.05)。结论:双波长激光结合数字化导板在上颌埋伏恒切牙的牵引中是一种更加舒适和省时省力的治疗方法。Objective:To investigate the clinical effect of dual-wavelength laser combined with digital guide plate in the traction of maxillary impacted central incisors.Methods:From June 2020 to June 2022,20 children with impacted maxillary central incisors,aged 7-10 years old,were collected from the Department of Pediatric Stomatology,West District,Hefei City Stomatological Hospital.The operation time,blood loss,and VAS value were recorded.The VAS value was recorded on the 1st,3rd,and 7th day after operation.The bracket dropout rate was recorded on the 1st,2nd,and 3rd month after operation.Results:The blood loss of the laser combined with digital guide group was less than that of the traditional scalpel group.In terms of operation duration,the average operation time in the laser combined with digital guide group was(22.4±5.9)min,and that in the traditional scalpel group was(44.0±16.8)min.The first day and the third day after surgery laser guide group number in the hierarchy of lower VAS score less than traditional scalpel group,and the results were statistically significant(P<0.05).There was no significant difference in VAS values during operation and on the 7th day after operation and in the bracket dropout rate at 1,2,and 3 months after operation between two groups(P>0.05).Conclusion:It is a more comfortable and time-saving method to treat the maxillary impacted permanent incisors with the combination of dual-wavelength laser and digital guide plate.
