RESUMO
Current artificial tooth materials include acrylic resin, improved resin, filled polyurethane dimethacrylate, and porcelain. The improved materials have been popularized by their ability to resist abrasion. A wide variety of abrasives, measuring instruments, and methods of wear testing make it difficult to assess study results that compare these materials. Clinical trials are needed to help establish a standard laboratory test.

This article reviews the advantages and disadvantages of denture base acrylic resins. Improvements in areas such as strength and speed of cure are discussed. The authors also emphasize the necessity for investigating the effects of factors other than denture base materials on the incidence of troublesome dentures.

An altered-cast impression technique that eliminates conventional cast-dissecting and impression-boxing procedures has been described. The master cast obtained by this method reproduces the teeth in anatomic form and the residual alveolar ridges in functional form.
