摘要
目的:探讨不同种植体表面处理对BLB种植体骨结合的影响。方法:6只Beagle犬,每犬双侧第二、三、四前磨牙即刻随机植入BLBⅠ(HA)、BLBⅢ(HA+SLA)种植体各3颗。术后2、4、8周各处死2只动物,选取BLBⅠ为A组,BLBⅢ为B组。通过大体标本、组织形态学及骨-种植体磨片观察等手段,观察术后2、4、8周时种植体的骨结合情况。应用SPSS12.0软件包对实验结果进行F检验。结果:种植术后2、4周,B组种植体骨结合率显著高于A组(P<0.05);术后8周,B组与A组种植体骨结合率无显著差异。结论:BLBⅢ种植体可在一段时间内缩短种植体周围骨的生长时间,提高种植体的骨结合率。
PURPOSE： To evaluate the effect of different surface processing of BLB implants on osseointegration. METHODS： Six Beagle dogs,thirty-six implants with different surface processing were divided into 2 groups （A：18 BLB Ⅲ implants with HA＋SLA surface processing ,B：18 BLBⅠimplant with HA surface processing）. Three BLBⅠand 3 BLB Ⅲ were placed into the mandible of each Beagle dog immediately and randomly at the 2nd, 3th, 4th pre-molars which were extracted under anesthesia. At the 2nd, 4th, 8th week after operation, two Beagles dogs were sacrificed,respectively. The specimen were observed by gross examination, histological examination, ground section of bone with implant. RESULTS： At the 2nd, 4th week, the bone contact rate of BLBⅢ group was significantly higher than that of BLBⅠgroup （P〈0.05）. At the 8th week, there was no significant difference between two groups. CONCLUSION： BLBⅢ shows considerable positive effect on osseointegration to implants in a short-time, but it’s not obvious after 8 weeks.
