Bond Strength of Reinforced Autopolymerized Acrylic Resin to Denture Base Resin

Figure 3

(a) Representative SEM images (x15, x1000) showing a mixed failure at bonding interface between rapid heat-cured acrylic resin and reinforced autopolymerized acrylic resin: (1) area of dislodged rapid heat-cured acrylic resin, (2) area of adhesive failure between two types of PMMA resin, and (3) area of intact reinforced autopolymerized acrylic resin.
