[show abstract][hide abstract] ABSTRACT: Dental casting alloys have played a major role in the restorative process for three-quarters of a century. Gold-based compositions were used almost exclusively for most of that time-but because of their relatively high cost, they began to be replaced by a number of base metal alloys. This article discusses some of the most recent findings about the composition of alloy systems and the possible tissue responses to those systems.

[show abstract][hide abstract] ABSTRACT: PRIMM, or polymer rigid inorganic matrix material, is a promising new substance. An original approach to improving resin composites is introduced. Domains of tough, strongly bonded crosslinked ceramic fibers improve physical properties and handling characteristics. PRIMM may be the posterior restoration of the future.

[show abstract][hide abstract] ABSTRACT: Composite resins have changed the nature of dental restorations. However, many dentists have not altered their cavity preparation process, relying largely on the same procedure used for amalgam restorations. The author proposes a more conservative procedure, retaining more sound tooth structure, for placing posterior composite resin restorations.
