Abstract
evaluate the effect of different surface treatments on tensile bond strength of acrylic denture teeth to prepolymerized Computer-aided design Computer-aided manufacturing poly methyl methacrylate (PMMA) denture base under two different storage conditions. Materials and methods: 160 test specimens were used in this study, each specimen has two parts: first part: acrylic cross linked maxillary central incisor denture tooth embedded in acrylic resin blocks and second part: cone shape
(5mm×5mm×3mm specimens prepared from prepolymerized PMMA discs by computer numerically controlled (CNC) milling machine under water cooling. 160 test specimens were divided into four main groups according to tooth surface treatment (40 each) group I: No sandblasting. group II: sandblasted using 50 μm aluminium oxide. group III: sandblasted using 150μm Al2O3. group IV: sandblasted using 200 μm Al2O3. Each group was divided into 2 subgroups (A, B) (20 each) subgroup A used resin cement to bond first part with second part. Subgroup B used bonding agent to bond first part with second part.
