Ceramic inlays and onlays: update 1995.

Tooth-colored inlays and onlays are increasingly sought by the public because of a growing interest in restorations that appear natural, and because of concerns about mercury in amalgam fillings. Following the introduction of bonded porcelain inlays in 1985, many of these restorations were placed. These inlays were a natural sequel to the porcelain laminate that reached North America in 1984, yet they did not enjoy the same rate of success. The advent of industrially fabricated porcelain blanks and the ability to copy-mill a positive as an inlay or onlay has resulted in a reliable and predictable dental restoration. Pressed ceramics, which are modelled by wax pattern, are also effective tooth-colored restorations.
