Abstract

Background and Aims: Debonding of denture TEETH from the denture base can be frustrating for both clinician as well as patient. The aim of this study was to determine the effect of different tooth preparation on the tensile BOND STRENGTH of composite denture TEETH to acrylic denture base material.Materials and Methods: In this experimental study, 108 anterior Glamour TEETH were selected and divided into 9 groups, based on their preparation (physical: no physical change, Glaze removal, Creating two slots with 1.5 mm depth, Creating a hole with 2.5mm depth. Chemical: (without chemical materials, monomer, silane). Specimens were prepared and tested according to the methods of the International standards organization (ISO 20795-1). After attachment of TEETH to acryl, the tensile bond stregth test was performed in a Universal Testing Machine (UTM) with a crosshead speed of 1mm/min and specimens were subjected to tensile force until failure. Data were analyzed with one-way ANOVA, Tukey HSD and Two-way ANOVA.Results: There were significant differences between the BOND STRENGTH of tested groups (P=0.012). Based on Tukey test, there was a significant difference between monomer/without physical change group and without/without (P<0.001) and control group. No significant differences were found between the BOND STRENGTHs of the other groups (P=0.17). All specimens were debonded as cohesive failure.Conclusion: Application of monomer on the ridge lap surface led to improve the tensile BOND STRENGTH between glamour composite denture TEETH and Iranian acrylic resin, however physical changes were not effective. According to the cohesive failure of all the specimens, it can be concluded that that the BOND STRENGTH between this type of TEETH and acrylic resin is stronger than the internal strength of TEETH.
