The purpose of this study was to evaluate the bond strengths of two abrasion-resistant plastic denture teeth (Endura, Duradent) bonded to pour-type denture base resin. The bond strengths of abrasion-resistant plastic denture teeth were compared with plastic tooth and porcelain tooth. The effects on bond strength produced by treatment of ridge-laps were also studied. Specimens were prepared and tested in accordance with JIS specification. The bond strengths of Endura, Duradent and the plastic tooth were not statistically different, and those were significantly lower than that of the porcelain tooth. The bond strengths of Endura and the plastic tooth were increased by treatment of ridge-laps surface with Dichloromethane and Duradent were increased by the same treatment and grinding ridge-laps.
