Five composite filling materials were finished using six finishing procedures currently in clinical use. The average roughness produced by each procedure was measured by means of a Surfanalyzer with four replications for each procedure on each of the five materials. Statistical analysis indicated that finishing with silicon carbide disks produced the smoothest surfaces. Acceptable surfaces were obtained with stones or with burs. Use of an alumina paste after a green stone-white Arkansas sequence did not produce a significant improvement. Two processes of filler particle abrasion were distinguished by means of electron microscopy: wear and shear. Fracture striations indicated particle shear. The roughest surfaces were produced by the use of a diamond instrument which is contraindicated. Acceptable finishing procedures for the composite materials tested include silicon carbide disks for accessible areas or 12 fluted finishing burs for more inaccessible areas.
使用目前临床使用的六种修整程序完成了五种复合填充材料的修整。每种程序产生的平均粗糙度通过表面分析仪进行测量，每种程序在五种材料中的每一种上重复测量四次。统计分析表明，使用碳化硅盘进行修整可产生最光滑的表面。使用磨石或车针可获得可接受的表面。在使用绿石 - 白阿肯色石序列后再使用氧化铝糊剂并没有产生显著改善。通过电子显微镜区分了两种填料颗粒磨损过程：磨损和剪切。断裂条纹表明颗粒剪切。使用禁忌的金刚石器械会产生最粗糙的表面。对于所测试的复合材料，可接受的修整程序包括用于可达区域的碳化硅盘或用于较难到达区域的12槽修整车针。
