Resumen

Introduction and objective: The favorable values of bonding strength with the preheating of the silane in various types of ceramics, it is proposed,To evaluate the effects of heat silane on the bond strength to microshear two types of cements dislicato lithium ceramics. Materials and methods: They were made 48 discs of 16 mm diameter and 1 mm thick ceramic based lithium disilicate (Ivoclar Vivadent, Ellwangen, Deutschland , Germany) were randomized into 4 groups; GNS hydrofluoric acid 9.6%, GS hydrofluoric acid 9.6% + silane application, GSC, 9.6% hydrofluoric acid + silane + implementation of blow-drying, GSH 9.6% hydrofluoric acid + silane + drying application with oven, each group were made tygon two cement types each with (n = 6) (Relix ARC and U200). Data were analyzed with two-way ANOVA test with post test Bonferrini. Results: For the cement Relyx ARC were: 09.3 ± 3.46 - GNS; GS- 12.4 ± 3.20; GSS- 13.5 ± 3.75 ; GSH- 12.9 ± 4.21; and cement U200: GNS- 12.1 ± 4.89; GS- 12.1 ± 3.71; GSS- 14.4 ± 3.33; GSH- 22.6 ± 4.33. Conclusion: Preheating of the silane increases the values of bonding strength between cement and ceramic lithium disilicate.
