Effect of Different Surface Modifications of Acrylic Teeth and Thermocycling on Shear Bond Strength to Polycarbonate Denture Base Material.During prosthodontic clinical practice, the most commonly reported type of failure is the debonding of teeth to the denture base.  This study aimed to study the influence of different surface modifications of acrylic teeth and thermocycling on shear bond strength to polycarbonate denture base material.  Each group was further subdivided into 2 categories depending on the thermocycling procedure (N = 10).  However, thermocycling has a nonsignificant decrease in the bond strength values in all experimental groups (P > 0.05) (B > D > C > A).  This study concluded that various surface conditioning methods affect the bonding strength of acrylic teeth and polycarbonate denture base material with no effect of thermocycling.
