Dental Restoration, Permanent Categories.

	Crowns - A prosthetic restoration that reproduces the entire surface anatomy of the visible natural crown of a tooth. It may be partial (covering three or more surfaces of a tooth) or complete (covering all surfaces). It is made of gold or other metal, porcelain, or resin.
	Inlays - Restorations of metal, porcelain, or plastic made to fit a cavity preparation, then cemented into the tooth. Onlays are restorations which fit into cavity preparations and overlay the occlusal surface of a tooth or teeth. Onlays are retained by frictional or mechanical factors.
	Marginal Adaptation (Dentistry) - The degree of proximity and interlocking of filling material to the wall of the cavity of a tooth. The term has come to be used synonymously with adaptation at the cavosurface margin. (Jablonski, Illustrated Dictionary of Dentistry, 1982; J Dent 1993;21:265-73)
