Fibre reinforcement enhances bonding of soft lining to acrylic dental and maxillofacial prostheses.
This study evaluated shear bond strength between Molloplast-B and different acrylic surfaces; smooth (group1), rough (group2) and Stick net fibre-reinforced interfaces (group 3). Shear tests were conducted with a universal testing machine. Bond failure categories were adhesive, cohesive and mixed failures. Mean bond strengths (SD) in MPa were Group 1, 0.59 (0.08); Group 2, 0.61 (0.08) and Group 3, 0.70 (0.09). There was statistically signiicant difference (p < or = 0.05) between group 3 and group 1 only. Modes of failure were different; mixed and cohesive only exhibited. StickTech Net fibre-reinforced surfaces exhibited stronger bond to Molloplast-B over non-reinforced interfaces, indicating promising clinical implications.
