Abstract:
In vitro localized wear testing was completed on several commercially available and experimental resin composites to evaluate the loss of occlusal contact wear. Marginal deterioration after localized stressing was also evaluated by SEM observation. The compositions containing zirconium silicate and quartz exhibited the least amount of wear. However, an experimental 4-META bonding resin exhibited the best marginal integrity.
