The double-inlay technique: a new concept and improvement in design.

Abstract

Gold and ceramic have long been used in prosthetic dentistry. In the posterior region, it is possible to use both materials with the double-inlay technique to add the strength of metal to the esthetics of ceramic. The problem, however, remains the volume of tooth reduction required to avoid ceramic fracture. This article describes a modification of the double-inlay technique that makes use of a pin system. This modified technique permits good retention while avoiding excessive tooth reduction.
