The significance of adhesive denture base resin

This article reviews the problems that occur at the metal-resin interface of removable partial dentures. The absence of a chemical bond between the denture base resin and the base metal alloy results in a potential for microleakage and bond failure at the junction. Recent development of a denture base resin that incorporates 4-META has been reported, primarily in the Japanese dental literature. The primary advantage of the 4-META resin system involves its bond to base metal alloys used in removable partial prosthodontics.
