Evaluation of alumino-silicate ceramic surface after different surface conditioning methods
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 75, Issue 1
Abstract
Purpose: of this paper was to evaluate changes in alumino-silicate glass ceramic surfacestructure and the bond strength to composite material after different surface conditioningmethods.Design/methodology/approach: Different conditioning methods of ceramic surfacewere applied: sandblasting, etching with hydrofluoric acid or both. Grounded ceramicsurface served as control group. To evaluate changes of ceramic surface structure CLSMmicroscopy was used and profilometric analysis of ceramic surface was performed. Shearbond strength of composite material to ceramics was tested.Findings: The highest bond strength between tested alumino-silicate ceramics andcomposite material was obtained after sandblasting followed by 5 min 9% HF.Research limitations/implications: Further research should be conducted to evaluatethe influence of surface treatment methods e.g. prolonged hydrofluoric etching time, onmechanical properties of ceramics.Practical implications: Extending HF etching time of glass-ceramic surface results inincreased surface area and allows to obtain high bond strength to composite material.Originality/value: Results of the study applies to clinical situation as the clinical outcomeand survival rate of dental all-ceramic prosthetic restorations depend on reliable bonding totooth structures.
