Objective To investigate the bonding properties and interface characterization of a domestic 3mol yttrium-stabilized tetragonal zirconium polycrystal(3Y-TZP)framework fired on with 4 different veneering ceramics for zirconia.Methods 4 different commercial veneering ceramics for zirconia(VITA VM9,SHOFU VINTAGE ZR,IPS e.max Ceram,Cercon ceram kiss)were sintered on 3Y-TZP rectangulars(15 mm×5 mm×S mm)according to the manufacturers' instructions for shear bond strength test,a metal-ceramic system(Ni-Cr alloy/VITA VMK95)was fabricated in the same type as a control group.Two bilayered specimens(3Y-TZP/VrTA VM9,Ni-Cr/VMK95)were prepared for scanning electron microscope(SEM)and energy distribution spectrum(EDS).Results The values of shear bond strength test were(18.83±1.77)MPa for 3Y-TZP/VITA VM9,(23.83±7.05)MPa for 3Y-TZP/SHOFU VINTAGE ZR,(17.87±2.30)MPa for 3Y-TZP/IPS e.max Ceram,(22.26±7.45)MPa for 3Y-TZP/Cercon ceram kiss,(20.55±5.13)MPa for Ni-Cr alloy/VITA VMK95.There was no statistically significant between all-ceramic groups and the control group(P>0.05).The failure modes in all-ceramic groups showed predominately adhesive at the interface.SEM showed the 3Y-TZP/VITA VM9 contacted tightly at the interface,while EDS detected Si element diffused into 3Y-TZP material.Conclusion The results indicate that domestic 3Y-TZP has a good interface compatibility with 4 commercial veneering ceramics,as a dental framework material,it can satisfy the clinical requirements.
