Abstract

Introduction: Acrylic teeth properties in complete denture prostheses are important in prosthesis survival. In this regard, tooth TENSILE BOND STRENGTH with denture base is very important. The purpose of this study was to compare TENSILE BOND STRENGTH of three kind of artificial teeth to denture base manufactured in Iran with a kind manufactured in Italy.Materials & Methods: In this experimental in vitro study, four kind of artificial teeth (Italian Ivoclar, Yaghoot, Herasit plus and Acradent) were used. Nine anterior and premolar teeth were selected and were prepared as Cylinders with 4mm diameter. Through flasking, toothbase was bonded to HEAT-CURED ACRYL. Samples were thermocycled for 2500times (5°C-55°C) and then were put in plastic pipes and under stretch to fracture by Zwick Z250 instrument. The data were analysed by One- Way ANOVA and Tukey test.Results: Mean TENSILE BOND STRENGTH was 260N for Ivoclar, 195N for Herasit, 124N for yaghoot and 54N for Acradent.Adhesive fracture percentage was 100% for Acradent, 60% for Ivoclar, 50% for yaghoot and 35.7% for Herasit. The rest was for cohesive fracture.Conclusion: The highest TENSILE BOND STRENGTH was seen with Ivoclar followed by Herasit, Yaghoot and Acradent respectively.
