Title

COMPARISON OF BOND STRENGTH OF COMPOSITE AND ACRYLIC TEETH TO HEAT-CURED AND AUTO-POLYMERIZED ACRYLIC DENTURE BASE

Pages

  215-226

Abstract

 Background and Aims: Failure of bonding between artificial teeth and denture base material is a considerable problem for patients who wear dentures. Because of the cost of denture repair and the expensive price of foreign artificial teeth, this study was designed to compare the BOND STRENGTH of COMPOSITE and acrylic artificial teeth with heat-cured and auto-polymerized denture base RESINs.Materials and Methods: In this experimental and in vitro study, two type of acrylic RESIN (heat-cured: Selectaplus H/ Trevalon, Dentsply and auto-polymerized: Rapid Repair, Dentsply) and four artificial teeth (acrylic Marjan New, COMPOSITE Glamour teeth which both of them are Iranian) and Ivoclar acrylic and COMPOSITE teeth were used. Therefore, 8 groups of 14 specimens each were evaluated. A shear bond strenghth test in a Universal Testing Machine was used. Data were analyzed using the 2-way ANOVA test. Results: The BOND STRENGTHs of ACRYLIC TEETH (Marjan New and Ivoclar) to heat-cured RESIN were similar (P=0.632) and statistically higher than those of COMPOSITE teeth (Glamour and Ivoclar). ACRYLIC TEETH (Marjan New and Ivoclar) and Glamour teeth had similar BOND STRENGTH to auto-polymerized RESIN, which showed the highest BOND STRENGTH values. Ivoclar COMPOSITE teeth showed significantly the lowest BOND STRENGTH (P<0.05). All ACRYLIC TEETH had the highest mean BOND STRENGTHs to heat-cured RESIN which were significantly different from that of auto-polymerized RESIN (P<0.05). However, the BOND STRENGTHs of all COMPOSITE teeth to both denture base RESINs were not significantly different (P>0.05).Conclusion: Based on the results of this study, the type of denture base material and artificial tooth may influence the failure load.
