The effect of repeated autoclaving on the implant-abutment connection of titanium abutments from Genesis and Bredent dental implant systems is of interest to dentists. 40 screw-retained titanium implant abutments from Genesis and Bredent were divided into four groups of ten. Each implant was secured with an abutment using screws. Abutments were prepared for the first 30-minute autoclave cycle at 121°C. After the first autoclave cycle, the abutments were fitted onto their implant systems and examined under a scanning electron microscope (SEM). Intra-group comparison between marginal gaps of Genesis and Bredent groups at 1st autoclave and 2nd autoclave observed statistically significant differences respectively (p<0.05). Genesis group showed highest mean values for buccal and mesial sides (2.7) and lingual and distal sides (2.8) with statistically significant differences. Marginal gap and surface roughness increased with autoclaving for both Genesis and Bredent group of implant abutment systems.
反复高压灭菌对创世纪和布雷登特牙科种植系统中钛基台的种植体-基台连接的影响是牙医们感兴趣的。来自创世纪和布雷登特的40个螺丝固位钛种植体基台被分成四组，每组10个。每个种植体用螺丝固定一个基台。基台在121°C下进行第一个30分钟的高压灭菌循环。第一个高压灭菌循环后，将基台安装到其种植系统上，并在扫描电子显微镜（SEM）下检查。创世纪组和布雷登特组在第一次高压灭菌和第二次高压灭菌时边缘间隙的组内比较分别观察到统计学上的显著差异（p<0.05）。创世纪组在颊侧和近中侧（2.7）以及舌侧和远中侧（2.8）显示出最高的平均值，具有统计学上的显著差异。创世纪组和布雷登特组种植体基台系统的边缘间隙和表面粗糙度都随着高压灭菌而增加。
