The slower the rotation of the cup, the less abrasion.
16. Polishing steps -Begin with the distal of the most posterior tooth.
-the stroke is from the gingival third toward the incisal/occlusal third of the tooth.
-apply enough light pressure so the cup flares into the sulcus 1-2mm.
-the recommended polishing pastes are those with high polish and low abrasion
levels.
-powder abrasives should be as wet as possible to minimize frictional heat.
-regular prophy paste generally is not recommended for polishing esthetic
restorations. Low-abrasive pastes such as micro-fine sapphire or diamond paste,
or aluminum oxide paste should be used for these restorations and polished
thoroughly for 30 secs with a rubber cup.
