dc.description.abstract	The most appropriate luting agent for attaching the prefabricated Ti-based insert of hybrid abutments to its ceramic component has not yet been determined. This study was done aimed at examining the micro-shear bond strength (?SBS) of different cements to commercially pure titanium (Cp Ti). A total of 100 milled cubes of Cp Ti was airborne-particle abraded using 250 ?m aluminum oxide particles. Specimens were then divided into 5 groups (n=20) according to the type of resin cement used: (1) Panavia F.2, (2) Rely X U200, (3) Panavia SA LUTING Plus, (4) GC Fuji I, and (5) GC FujiCEM 2. After 24h storage, half of the samples were subjected to 5000 cycles of thermal aging. Next, the bonded samples were tested in the micro-shear mode. Data (MPa) were analyzed using a two-way ANOVA and the post hoc Tukey test (?=0.05). After debonding, each sample was examined for the failure mode classification. The highest ?SBS value in the study cements was obtained for Panavia F.2 cement (P<0.001) with no significant difference with Rely X U200 (P=0.07). The ?SBS values of both GI-based cements were significantly lower than those of resin cements. Thermal aging decreased the ?SBS values of all groups (P=0.003) significantly. The mainly occurred failure mode in all groups was the adhesive feature. Resin cements demonstrated acceptable bonding to Cp Ti, yet Gl-based cements did not. From among the cements examined, Panavia F.2 can be considered as the best option for bonding to Ti.	es
