Dental Materials

a procedure used to reduce excess restorative materials to develop appropriate occlusion and contour; this is sually done with rotary cutting instruments. it removes sufrace blemishes and produces a smooth surface. it requires the hardest appropriate material except at the margin of the restoration, where tooth structure may be affected

a procedure that produces a shiny, smooth surface by eliminating fine scratches, minor surface imperfections, and surface stains using mild abrasives frequently found in the form of pastes or compounds. It produces little change in the surface. It may have to be repeated periodically during the life of the restoration if tarnish or stains develop. It requires materials with a Mohs' hardness of only 1 to 2 units above the substrate getting this type of procedure done?

a material composed of particles of sufficient hardness and sharpness to cut or scratch a softer material when drawn across its surface

the particle size of the abrasive, typically classified as coarse, medium, fine and superfine

a procedure that is primarly meant to remove soft deposits from the surface of restoartions and tooth structures. polishing and this are done to remove surface stains and soft deposits from the clinical crown and exposed root surfaces of teeth after all hard deposits are removed. aside from abrasives, there are also chemical products that are primarly used for removable appliances. this requires materials with mohs' hardness no greater than equla to the substrate

a procedure for removal of excessive restorative material from margins of restorations
