Comparison of tensile bond strength between implant abutments and all ceramic restoration luted with four luting agents-An in-vitro study
Journal Title: Scholars Journal of Dental Sciences - Year 2015, Vol 2, Issue 1
Abstract
Abstract: The choice of luting agents contributes a significant role in retention of cement retained implant restorations and their precise tensile behaviour needs to be investigated further. The aim of present study is to estimate and compare the difference in tensile bond strength between implant abutments and all ceramic restorations luted with four luting agents. An experimental, single blinded, in-vitro study design was employed. A total of 40 machined, conventional commercially pure titanium abutments were divided into four groups of ten each and attached to the implant fixtures. Full coverage all ceramic restorations were fabricated, luted with four cements(Group A–Zinc phosphate, Group B-Glass ionomer, Group C–Resin cement, Group D–Zinc oxide eugenol) and evaluated for tensile bond strength in the universal testing machine set at 0.5 mm per minute cross head speed following immersion in artificial saliva with pH 7 at 37℃ and thermocycling. Statistical analysis was done by Independent sample T test and One-way ANOVA at 0.5 level of significance. The four luting cements used in this study had the following tensile bond strength values. Group A(Zinc phosphate cement)222.5 +/- 6.498 N, Group B(Glass ionomer) 93 +/- 3.28 N, Group C(Resin cement) 373 +/- 6.68 N and Group D(Zinc oxide eugenol) 44 +/- 2.02 N respectively. Both the Independent sample T test and ANOVA showed statistically high significant difference (p<0.001) between all the four experimental groups. The highest tensile bond strength was exhibited by the resin luting cements followed by zinc phosphate, glass ionomer and Zinc Oxide Eugenol respectively following luting the all ceramic restorations with implant abutments and the clinicians could choose the appropriate cement based on their clinical requirement and judgement of the existing clinical situation. Keywords: Tensile bond strength, Luting cement, Implant abutment, All-ceramic restorations.
