Effect of maleic anhydride pretreatment on tensile bond strength of a silicone soft liner to a denture base polymer.

Purpose: To determine the effect of resin surface treatment with dissolved maleic anhydride in butanone added into primer on the tensile bond strength between an acrylic denture base resin and a silicone soft liner.

Materials And Methods: To test tensile bond strength, standard dumbbell-shaped acrylic specimens were prepared. Five experimental groups, including the control, were tested (n = 5).
