摘要: 目的探讨不同钛基底表面处理对钛与树脂粘接强度的影响。方法将纯钛试件随机平均分组:光滑组(A组)、酸蚀组(B组)、喷砂组(C组)、喷砂+酸蚀组(D组)、微弧氧化组(E组)、氮化钛涂层组(F组)。根据以上分组,对试件进行相应的表面处理,用粗糙度仪进行钛表面粗糙度测量,后与Cemerage冠桥树脂结合,扫描电子显微镜(SEM)观察试件表面形貌,能谱分析仪(EDS)对表面元素进行分析,万能试验机检测试件与Cemerage冠桥树脂的粘接强度。结果各组的粗糙度分别为A组(0.370±0.039)µm;B组(1.456±

Abstract: Ojective This study aims at assessing the effect of different surface treatment on bonding strength of titanium and resin. Methods Metal specimens were prepared to divide into six groups randomly like following: polishing(group A), etching(group B), sandblasting(group C), sand blasting and etching(group D), microare-oxidation(group E), TiN film(group F). According to the groups, to treat the metal specimens, and to take one from each group to measure the surface roughness with a roughness machine after that all the specimens were coated with crown and bridge composite resin to fixed area. The fracture surface morphology of the titanium-resin was observed using a scanning electron microscope(SEM) and the energy dispersive X spectrometer to analysis the elemental composition. The shear bond strengths of the specimens were evaluated by a Universal Testing Machine. Results The surface roughness of each group were (0.370±0.039) μm for group A, (1.456±0.044) μm for group B, (2.044±0.019) μm for group C, (1.970±0.047) μm for group D, (0.683±0.023) μm for group E, and (2.195±0.066) μm for group F. The shear bond strengths of each groups were (5.84±0.30) MPa for group A, (10.22±0.63) MPa for group B, (10.78±0.45) MPa for group C, (12.24±0.46) MPa for group D, (13.82±0.61) MPa for group E, and (16.81±0.74) MPa for group F. We can find polymerization porcelain remain on titanium porcelain metal surface of group B to group E, by watching through the results of SEM. Conclusion Sandblasting and etching together, microare-oxidation and TiN film can improve the bonding strength of titanium and crown and bridge composite. resin obviously.

Key words: titanium, resin, microare-oxidation, bond strength
