Wear rates of various artificial tooth materials: a literature review.
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.
