Abstract
ABSTRACT
Purpose: To compare the effects of three surface treatments on bond strength between acrylic teeth and polyamide denture base.
Material and Methods: 60 specimens, each composed of maxillary central acrylic cross-linked incisor tooth processed onto thermoplastic polyamide denture base according to the Japanese Standards Association 6506. Test specimens were divided according to the experimental design: Surface treatments (sandblasting, T-shape diatoric holes, or both). The specimens were then subjected to shear load with the Universal Testing Machine. Load was applied till denture teeth separated from the base resin. The resulting debonding forces were recorded and statistically analyzed by using T student-test and ANOVA test followed by Tukey HSD test. The interface where failure occurred was inspected to determine the type of failure whether adhesive or cohesive.
Results: Statistical significant differences were found in bond strength among the different surface treatment groups (P<0.05).
Conclusion: Within the limitations of this in-vitro study, under normal storage condition, it can be concluded that sandblasting of the diatoric holed teeth give the highest bond strength.
