In this study the influence of various physical ve chemical surface preparation methods on the bond strength of all-ceramic restorations to resin cement were evaluated. Identifying the best possible bond strength was the purpose. In the study dental lithium disilicate glass ceramic was bonded to dual-cure resin cements.Various treatments were applied to ceramic surface; two different acids, four silanes, three different application methods for silanes. These were phosphoric acid and hydrofluoric acid for acid treatment, Monobond Plus, Clearfil Ceramic Primer, Bis Silane and GC Ceramic Primer for silanes, drying at room temperature air, hot air owen and hot air owen + hot water bath for silane application methods. Treated ceramics were directly bonded to dual-cure resin cement. Shear bond strength test was applied and debonded surfaces were examined with stereomicroscope. Results; bond strength values were 22,6 MPa for HF acid; two bottled, non-acid recommended, adhesive monomer containing silane; hot air drying and hot water bath group; 21,9 MPa for HF acid, one bottled non-acid recommended, adhesive monomer containing silane; hot air drying and hot water bath group. Other groups were resulted lower bond strength values although these were no statistically difference. Conclusions are; aggressively dried silane groups generally showed an increased the bond strength values for one bottled non-acid recommended, adhesive monomer containing silane and two bottled, non-acid recommended, adhesive monomer containing silane, applied to HF acid primed ceramic. Possible clinical outcomes are; when one bottled non-acid recommended, adhesive monomer containing silane applied to HF acid primed lithium disilicate glass ceramic surfaces and two bottled, non-acid recommended, adhesive monomer containing silane applied to HF acid primed lithium disilicate glass ceramic surface, hot air drying and hot water bath can increase the bond strength of ceramic to resin cement. Keywords : phosphoric acid, hydrofluoric acid, lithium disilicate glass ceramic, shear bond strength test, silane.
