To compare the surface roughness produced by various implant curets on titanium implant abutment surfaces.
Each of six titanium implants was divided into four quadrants, three experimental and an untreated control surface. The three experimental surfaces were instrumented with a gold platinum curet, an unreinforced resin curet, or a reinforced resin curet. Two implants were assigned to each of the following treatments: 128, 256 or 512 scaling strokes within a 4 mm wide area. Photographs were taken of the surfaces with a scanning electron microscope at approximately x500 magnification and classified by six investigators according to surface roughness.
The surfaces were different at 8 and 16 years with P < 0.01 and P < 0.0005, respectively. At 8 years, the surface roughness was significant between the treatments in the following ascending order: untreated, unreinforced resin curet, reinforced resin curet and gold platinum curet. Significant roughness was observed for surfaces treated by only the gold platinum curet and the reinforced resin curet at 16 years. The gold platinum curet created the roughest surface P < 0.0006.
比较各种种植体刮治器在钛种植体基台表面产生的表面粗糙度。
将六枚钛种植体中的每一枚均分为四个象限，即三个实验表面和一个未处理的对照表面。三个实验表面分别用金铂刮治器、未增强树脂刮治器或增强树脂刮治器进行处理。为以下每种处理分配两枚种植体：在4毫米宽的区域内进行128、256或512次刮治行程。用扫描电子显微镜以约500倍放大倍数拍摄表面照片，并由六名研究人员根据表面粗糙度进行分类。
在8年和16年时表面存在差异，P值分别<0.01和<0.0005。在8年时，各处理之间的表面粗糙度按以下升序排列具有显著性：未处理、未增强树脂刮治器、增强树脂刮治器和金铂刮治器。在16年时，仅用金铂刮治器和增强树脂刮治器处理的表面观察到显著粗糙度。金铂刮治器产生的表面最粗糙，P<0.0006。
