A wear process
Abrasion
Abrasive particles are bonded to paper, metal, or plastic backing to form disc
Abrasive Disc
A process of smoothing a surface by rubbing lightly with a specially designed instrument or cotton pellet. The effects are improved marginal adaptation and increased hardness
Burnishing
The removal of excess filling material, using special instruments. The goal is to produce accurate anatomic contours and restore form and function to the tooth.
Carving
The junction of any wall of a cavity preparation with the unprepared tooth structure.
Cavosurface Junction
chemical and electrochemical deterioration on the surface and the subsurface of an amalgam restoration that usually begins at tarnish
Corrosion
placed and formed in the cavity preparation; includes amalgam, composite resins, and glass ionomer cement
Direct Restoration
Formation of a gap or groove between the cavity preparation margin and the restorative material
Ditching
process that invovles removing marginal irregularities,defining anatomic contours, and smoothing away surface roughness of a restoration
Finishing
Type of overhanag in which a thin layer of restoration extends beyond the cavosurface junction: also called a feather ledge
Flash
The size of the abrasive particle
Grit
Formed on a die reproduction of a prepared tooth then cemented into place: includes porcelain, gold inlays, and porcelain crowns.
Indirect Restoration
Process of removing excess restorative material and applying finishing techniques to restablish a smooth,well-adapted cavosurface
Margination
An excess of restorative material such that the normal anatomic form is altered
Overconture
Area of a restoration where the restorative material extends outward past the cavosurface margin of the cavity preparation
Overhang
Process carried out after placement of a restoration to remove minute scratches from the surface of a restoration and obtain a smooth, shiny luster.
Polishing
A paste containing polishing agents that is applied to teeth with a rubber cup and handpiece for cleaning purpose
Prophylactic Paste
Instrumentation to reshape and remove marginal excess and to restore the natural anatomic form
Recontour
A discoloration of the surface of a metal restoration, usually from sulfides. Caused by lack of cleanliness, biofilm accumulation, and certain foods
Tarnish
