Machined titanium substructures for fixed, complete arch prostheses have been used with various surface pretreatments to enhance acrylic bonding. Since traditional mechanical methods for denture base material retention cannot be used, silane and surface abrasives have been used to enhance retention. The purpose of this study was to determine if a metal bonding denture base material provided a favorable bond strength to machined titanium. Fifteen rod-shaped samples of commercially pure Grade 2 titanium were divided into two groups, five samples representing the control group and 10 samples for the experimental group. The rod samples for the control received no pretreatment, while the experimental samples were pretreated with 110 microns alumina abrasive. Meta-Dent heat-cured polymethyl methacrylate was processed around each sample in a secondary cylindrical shape approximately 0.9 x 1.0 centimeters with the titanium rods extending from each end. A Shell-Nielsen shear test was then performed at a crosshead speed of 0.5 millimeters/minute to determine the bond strength. The experimental group demonstrated a mean bond strength 3.7 times greater than the control group (significant, P = 0.0001, ANOVA). Pretreatment with 110 microns alumina air abrasive significantly enhanced the bond strength of heat-cured metal bonding polymethyl methacrylate to titanium.
