激光辅助凝血在美学区种植修复中的应用

目的探讨上前牙美学区域种植修复中激光辅助凝血的临床应用及疗效。 方法2011年12月至2014年10月，收治上前牙美学区域牙位缺失患者24例，埋植式植入种植体5个月后接受二期手术，随机分为激光照射组（12例）和非照射组（12例）。照射组采用激光辅助凝血，非照射组采用常规缝合止血。术后印模制作及佩戴临时冠，1~ 3个月后制作终义齿，临床观察6~ 34个月。记录制取印模、终义齿时间，用红色美学指数（PES）计分标准进行计分，并对患者满意度进行调查。 结果24例均成功完成种植义齿修复，激光照射组制作终义齿时间为（10.25 ± 1.14）d，非照射组制作终义齿时间为（26.08 ± 3.55）d，差异具有统计学意义（t=-13.871，P= 0.000）。照射组PES得分最高14分，最低7分，中位数为12.5；非照射组PES得分最高11分，最低7分，中位数为7.0；差异具有统计学意义（Z= 3.341，P= 0.001）。 结论激光辅助凝血促进种植体周围软组织修复，缩短临时及永久修复时间，美学区域行种植修复能够获得良好的临床效果。

The application of laser assisted coagulation in dental implant restoration

ObjectiveTo investigate the clinical application and therapeutic effect of laser assisted coagulation in the promotion of tissue regeneration in dental implant restoration. MethodsFrom December 2011 to October 2014, 24 cases of patients with defections in anterior aesthetic region underwent implantation. Six months later, they receiving two-stage operation, they were randomly divided into laser group (12 cases) and non-irradiated group (12 cases) . Laser group used laser assisted coagulation, while non-irradiated group used conventional suture hemostasis. Impression and temporary crown were made postoperatively. The end of the denture fabrication was made after 3-6 months. Clinical observation was lasted for 6-34 months. Pink esthetic score (PES) was used to evaluate the effect of aesthetics, and a survey of patient satisfaction was putted. ResultsThe implant denture restoration was completed successfully in 24 patients. The final denture time was (10.25 ± 1.14) d in laser group and (26.08 ± 3.55) d in non-irradiation group. The difference between two groups was statistically significant (t=-13.871, P= 0.000) . The highest and the lowest PES score was 14 points and 7 points, respectively; and the median score was 12.5 in laser group. The highest and the lowest PES score was 11 points and 7 points, respectively; and the median score was 7.0 in non-irradiated group. The difference between two groups was statistically significant (Z= 3.341, P= 0.001) . ConclusionLaser assisted coagulation promote soft tissue reparation and shorten the temporary and permanent repair time, aesthetics in the process of implant can obtain good clinical effect.
