Microtensile Bond Strength of Zirconia Ceramics with Different Surface Treatments
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
Objectives: The aim of this in-vitro study was to evaluate the hydrolytic stability of different surface treatments on the bond strength of yttrium-oxide-partially-stabilized zirconia ceramics. Materials and Methods: InCoris TZI C (Sirona Dental Systems GmbH, Germany) zirconia blocks were sintered according to the manufacturer's instructions and randomly divided into three groups according to the surface treatment methods as follow;Group I: Air particle abrasion, Group II: Air particle abrasion followed by piranha acid etch solution, and Group III: Air particle abrasion followed by hot acid etching solution. Zirconia blocks were bonded to the pre-constructed composite blocks using Panavia SA cement Plus. Microbars from each subgroups were randomly selected, half of them were subjected to the testing procedures without thermalcycling, while the other half were subjected to 10,000 thermalcycles. Microtensile bond strength testwas performed using a universal testing machine (0.5 mm/min). Results:There was, a significant difference (P<0.05) between the three main surface treatment. Conclusion: The bond strength was influenced by the different surface treatment methods, and aging process.
