Ikeda M, Martin K, Nikaido T, Foxton RM, et al. Ten specimens of each composite resin were randomly subjected to one of the following finishing/polishing techniques: A -- carbide burs; B -- fine/extrafine diamond burs; C -- Sof-Lex aluminum oxide discs; D -- Super-Snap aluminum oxide discs; E -- rubber polishing points + fine/extrafine polishing pastes; F -- diamond burs + rubber polishing points + fine/extrafine polishing pastes; G -- diamond burs + Sof-Lex system; H -- diamond burs + Super-Snap system. Jaramillo-Cartagena R, Lpez-Galeano EJ, Latorre-Correa F, Agudelo-Surez AA. However, cups and points will help develop more realistic characterization when polishing a veneer. FineThis part of the grit sequence is where polish really starts to shine through. One or two times through the interproximal should be sufficient, followed with the fine-superfine aluminum oxide strip on dry surface until no resistance is felt, and a smooth surface is apparent.
