Abstract :

Aim: Purpose of this study was to compare and evaluate of Shear bond strength between Zirconia and Resin after surface treatment with different Phosphate based bonding agents. Material and methods Zirconia substrates was used for bonding procedures. 96 samples were prepared. Pre sintered zirconia blanks were milled and sintered at 1600oC. Zirconia surfaces are surface treated with Monobond N ( Ivoclar,VivadenT), AZ Primer ( Shofu, Shofu dental corporation, Germmany.),Z Prime Plus ( Bisco, Inc. Schaumburg, IL U.S.A.). Resin stubswere prepared using flowable resin ( Te Econom flow, Ivoclar,Vivadent.) and are bonded to zirconia substrate. Samples are three groups group M, group AZ, group Z. Shear bond testing is done using universal testing machine. Results There was significant difference in shear bond values between group M, group AZ, group Z. Pair wise comparison showed significantly higher values for group M and group Z. Conclusion: Surface treatment of zirconia with Monobond N and Z Prime plus showed increase in bond strength in combination with air aasion
