Title

EVALUATION OF BOND STRENGTH OF FOUR TYPES OF MULTILITHIC TEETH TO ACRYLIC DENTURE BASE MATERIAL

Pages

  240-247

Abstract

 Background and Aim: The wear resistance of composite denture teeth has been well investigated, but there have been few studies about the bonding of these teeth to acrylic denture base resins. The aim of this study was to evaluate the BOND STRENGTHs of four brands of multilithic denture teeth to acrylic denture base material.Materials and Methods: In this experimental laboratory study four denture teeth groups (Glamour, Yaghout, Ivoclar and Apple) were used. Of each type of denture teeth 20 specimens were dogged into four wax prisms so that the lingual surface was faced upwards and the long axis of each of them made an angle of 90 degrees with the edge of the prism. After the placement of acryl and their curing stages, each sample was tested under shear-compressive force of 5 mm/min speed until fractured occurred. The data were analyzed by ANOVA and TUKEY test at 0.05 significance level.Results: Apple teeth had the highest mean BOND STRENGTH (1337±414/99) followed by Yaghoot (1097/36±142/86), Ivoclar (945±366/43) and Glamour (880±285/80). Statistical analysis showed significant difference between the mean BOND STRENGTH in some of denture teeth. Ivoclar specimens had the highest percentage of cohesive fracture followed by Apple, Glamour and Yaghoot. Nevertheless, statistical analysis showed no significant difference between the percentages of cohesive fracture in different groups of denture teeth.Conclusion: The results of this study showed that the BOND STRENGTH of Apple denture teeth is more than Ivoclar and other denture teeth that were used in this stud.
