Abstract

Present study aimed to improve the bond strength of denture teeth to acrylic resin denture base by chemical or mechanical modification on the bonding surface of denture teeth. Total 40 artificial acrylic resin central incisors and lateral incisors were divided into five groups: group I, 8 samples without modification (control group); group II, 8 samples (bonding surface of teeth were treated with monomer); group III, 8 samples (bonding surface of teeth were treated with monomer and the glaze layer removed with aluminum oxide stone bur); group IV, 8 samples (bonding surface of teeth were treated with acetone); and group V, 8 samples (acetone application followed by glaze layer removed with aluminum oxide stone bonding surface of acrylic resin teeth). They were mounted on wax blocks, and the blocks were acrylized. The bond strength values were obtained by subjecting the samples to shear compressive load under universal testing machine. The results were subjected to statistical analysis. The mean value of bond strength was highest for group E (modified by aluminum oxide abrasion prior to dichloromethane application), followed by group C (modified by aluminum oxide abrasion prior to monomer application), group D (modified by dichloromethane application), group B (modified by monomer application).
