摘要
研究了粘结剂对钴铬合金瓷贴面前金属-陶瓷粘结强度的影响。三种陶瓷体系：Initial MC (IMC), Hera Ceram （HC）和ZEO CE LIGHT （ZCL）在锻造子结构上进行了测试。ZCL系统还在铸造子结构上进行了测试。进行三点弯曲试验，并用电子探针显微分析和x射线衍射对断裂表面进行分析。所有试件的粘结强度均超过ISO 9693:2019 （>25 MPa）的要求。ZCL粘结剂显著提高了锻造亚组织和铸造亚组织的粘结强度，而IMC和HC粘结剂则没有显著提高。锻造zcl试件的粘结强度明显高于铸造zcl试件。在结合强度较高的试样中，在脱粘的金属表面主要检测到硅和钛的存在。因此，粘结剂对粘结强度有积极影响，但取决于陶瓷体系和亚结构类型。
Influence of bonding agents on metal-ceramic bond strengths for Co-Cr alloy.
This study investigated the influence of bonding agents on metal-ceramic bond strengths before porcelain veneering for cobalt-chromium alloy. Three ceramic systems: Initial MC (IMC), Hera Ceram (HC), and ZEO CE LIGHT (ZCL) were tested on wrought substructures. The ZCL system was also tested on cast substructures. Three-point bending test was performed, and fractured surfaces were analyzed using electron-probe microanalysis and X-ray diffraction. The bond strengths of all specimens exceeded the requirements of ISO 9693:2019 (>25 MPa). The ZCL bonding agent significantly improved bond strengths for wrought and cast substructures whereas the IMC and HC bonding agents did not. Wrought-ZCL specimens exhibited significantly higher bond strengths than cast-ZCL specimens. In the specimens exhibiting higher bond strength, silicon and titanium, which originated from the bonding agent, were predominantly detected at the debonded metallic surfaces. Consequently, the bonding agent positively affected the bond strength but depended on the ceramic system and substructure type.
期刊介绍：
Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
