| 摘 要： | 目的考察国产氧化钇稳定四方晶体氧化锆（3Y-TZP）与4种氧化锆专用饰面瓷界面的结合性能。方法粉浆涂塑方法分别将VITA VM9、SHOFU VINTAGE ZR、IPS e.max Ceram、Cercon ceram kiss 4种氧化锆专用饰面瓷烧结在15 mm×5 mm×5 mm的3Y-TZP核瓷试件上，另外制作相同尺寸镍铬合金烤瓷试件作为对照，测试界面剪切强度。制作氧化锆基底与饰面瓷双层瓷试件，扫描电镜（SEM）观察结合界面微观形貌；能谱分析（EDS）检测界面元素分布。结果氧化锆与VITA VM9、SHOFU VINTAGE ZR、IPS e.max Ceram、Cercon ceram kiss 4种氧化锆专用饰面瓷的剪切强度分别为（18.83±1.77）MPa、（23.83±7.05）MPa、（17.87±2.30）MPa、（22.26±7.45）MPa，各组与金属烤瓷对照组比较，差异均无统计学意义（P＞0.05）。各3Y-TZP烤瓷组试件破坏模式以界面破坏为主。扫描电镜观察氧化锆和饰面瓷结合界面结合紧密；能谱分析结果显示二者存在化学元素渗透。结论国产3Y-TZP与饰面瓷材料界面结合良好，可以满足临床需要。

| Abstract: | 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. |
