Wear of two artificial tooth materials in vivo: a 12-month pilot study.

Statement Of Problem: Wear of methacrylate artificial teeth resulting in vertical loss is a problem for both dentists and patients.

Purpose: The purpose of this study was to quantify wear of artificial teeth in vivo and to relate it to subject and tooth variables.

Material And Methods: Twenty-eight subjects treated with complete dentures received 2 artificial tooth materials (polymethyl methacrylate (PMMA)/double-cross linked PMMA fillers; 35%/59% (SR Antaris DCL, SR Postaris DCL); experimental 48%/46%).
