Effective use of rotary cutting burs and bonded, coated, and loose abrasives can greatly simplify and improve the effectiveness of finishing and polishing procedures. Fluted carbide finishing burs appear to be the optimal rotary contouring devices for posterior composite resins. Finishing diamonds are preferred for gross finishing of adjusted porcelain. Coated abrasive discs and strips provide unique interproximal and incisal access and are preferred for finishing and polishing of microfil resins. Rubberized bonded abrasives have evolved to provide a greater range of finishing and polishing action on composite resin and for polishing porcelain. A wide selection of aluminum oxide and diamond polishing pastes, together with highly effective felt and foam application devices, are now available to polish composite and porcelain to an enamel-like appearance. Aluminum oxide composite polishing pastes are highly effective and strongly recommended for use on highly filled hybrid composites but have limited utility on microfil resins, with use of extrafine (0.3-mu) pastes clearly contraindicated.
有效使用旋转切割车针以及粘结、涂层和松散磨料，可极大地简化并提高修整和抛光程序的效率。带槽硬质合金修整车针似乎是用于后牙复合树脂的最佳旋转塑形器械。修整金刚石更适合用于调整后瓷材的粗修整。涂层磨盘和磨带可提供独特的邻面和切端操作途径，是微填料树脂修整和抛光的首选。橡胶粘结磨具已得到改进，可对复合树脂进行更大范围的修整和抛光，并用于瓷材的抛光。现在有多种氧化铝和金刚石抛光膏可供选择，还有高效的毡和泡沫涂抹装置，可将复合树脂和瓷材抛光至类似牙釉质的外观。氧化铝复合抛光膏非常有效，强烈推荐用于高填料混合复合树脂，但对微填料树脂的效用有限，显然禁用极细（0.3微米）的抛光膏。
