Abstract

Objective: This research aimed to evaluate the effect of differentresin cement (RC) types, compare the effect of surface treatmentsand bonding applications and evaluate the effect of thermal cyclingon bond strengths to Titanium (Ti) surfaces.Methods: A total of 240 Ti discs (10x3 mm) were randomly dividedinto two groups. Half of the specimens were sandblasted with 110µm Al2O3 particles, whereas the other half had no surface treatments(non-treated). Both sandblasted and non-treated specimens of eachsurface treatment type were divided into five subgroups, whichreceived one of the following surface conditions and luting selfadhesive resin cement: (a) Panavia SA Cement, (b) Clearfil SE Bond+ Panavia SA Cement, (c) RelyX U200, (d) Single Bond Universal+ RelyX U200 and (e) MIS Crown Set Cement. A mould with a4-mm diameter and 2-mm thickness was applied to the centralregion of the specimens. Each group was divided into subgroups,according to whether performing thermocycling or not. The shearbond tests were conducted at a crosshead speed of 1 mm/min. Data(N) were analysed using one-way analysis of variance and Tukey’shonestly significant difference tests (p<0.05).Results: The sandblasted + bonding agent groups provided highershear bond strength than the non-treated groups for all RC types(p<0.05). Sandblasted Clearfil SE Bond + Panavia SA Cement(non-thermocycled) showed the highest values (182.761±41.55),whereas the MIS Cement (17.681±9.33) and Panavia SA Cement (15.32±7.38) non-treated (thermocycled) groups had the lowestvalues.Conclusion: Sandblasting and bonding agents can improve bondstrength. The thermocycling period decreased the bond strengthvalues for all groups.
