Abstract
The purpose of this study is to compare tensile bond strength between Cr-Co alloy and three denture base resins after surface treatment. Following the manufacturer´s instructions, 180 bonded specimens were made from three denture base resins (Lucitone 199, Paladent 20, POSS resin) and three surface treatment methods(sandblasting, metal primer, silicoating). 20 samples were made in each group and a half was thermocycled 1000 times between 5℃ and 55℃. The tensile bond strength was measured using an Instron with 5mm/min crosshead speed. Data was analyzed with one-way ANOVA, T-test and Duncan test. The results were as follows: 1. Samples with metal primer coating had significantly high tensile bond strength than the other surface treated groups (p<.05). Significantly low tensile bond strength was shown in sand blasted groups (p<.05). 2. No significant difference was observed in metal primer coating groups before and after thermocycling (p>.05). 3. Tensile bond strength was decreased in silicoated samples after thermocycling (p<.05). 4. Of the surface treated groups with metal primer,Lucitone 199 had the greatest bond strength and POSS resin and Paladent 20 were followed (p<.05). 5. Of the surface treated groups with silicoating, POSS resin and Lucitone 199 had greater bond strength than Paladent 20 (p<.05).
