Is the Bond Between Acrylic Resin Denture Teeth and Denture Base Resin Stronger if They are Both Made by the Same Manufacturer?

Abstract - A previous study suggested that a stronger bond may be achieved between acrylic resin denture base material and acrylic denture teeth when both are made by the same manufacturer. Three denture base acrylic resins from three different manufacturers were bonded to three different acrylic resin denture teeth, one of which was manufactured by each of the manufacturers of the base material. In each group there was a trend that the bond strength achieved between the teeth and base material from the same manufacturer was higher than the unmatched pairs but statistical significance was not achieved.

KEY WORDS: Acrylic resin, denture teeth, bond strength
