Er:YAG激光在种植二期手术中与常规手术方法的对比研究

The comparison of Er: YAG laser and routine operation method in second-stage implant surgery

目的研究Er:YAG激光在种植二期手术中的临床应用,探讨其与常规手术方法相比的优缺点,以期为种植二期手术寻找更好的临床方法。方法收集我院种植中心进行种植二期手术的患者60例,随机分为A、B、C三组,各20例。其中A、B两组作为对照组,C组作为实验组。A组采用常规切开法,B组采用电刀切开法,C组采用Er:YAG激光切开法。分别通过检测各组患者手术中出血情况,手术时长(min),术后患者的疼痛时间(h),术后患者的疼痛等级(VAS),术后牙龈组织愈合的时间(d),来评估不同手术方法对种植二期手术中多项指标的影响。结果 A组与C组比较,两组术中出血量、手术时长、术后疼痛时间、术后VAS评分及术后牙龈组织愈合时间,差异有统计学意义(P<0.05)。B组与C组比较,两组术中出血量、手术时长、术后疼痛时间、术后VAS评分及术后牙龈组织愈合时间,差异有统计学意义(P<0.05)。结论与常规切开组及电刀切开组比较,Er:YAG激光在种植二期手术的多项指标中有明显的优势,有良好的临床应用前景。

Objective To study the advantage of Er：YAG laser in second-stage implant surgery compared with traditional operation method, and provide better treatment method in second-stage implant surgery.methods 60 patients who needed second-stage implant surgery in our hospital were randomly divided into 3 groups （A,B and C）.There are 20 patients in each group.Group C was experimental group,Group A and B were as control.The patients from group A was treated with traditional incision method,which was treated with electrotome in group B, and patients from group C were treated with Er：YAG. To evaluate the influence of different methods on soft tissue healing.Bleeding during surgery,the operation time （min）,the duration of postoperative pain（h）,Visual Analogue Scale（VAS）,and gingival postoperative healing time were evaluated and recorded.These variables among three groups were compared respectively to detect the influence of Er：YAG on gingival soft tissue healing.Results There was significant difference in the amount of bleeding during surgery,the operation time,The duration of pain,the average vas score and the healing time between group A and group C （P〈0.05）.There was significant difference in the amount of bleeding during surgery,the operation time,The duration of pain,the average vas score and the healing time between group B and group C （P〈0.05）.Conclusion Compared with traditional incision method and electrotome group, there are several advantages in Er-YAG in second-stage dental implant surgery,and has a good application prospect.
