抄録

A new porcelain fused to a metal system consisting of a universal gold alloy and a low-firing porcelain for veneering was introduced with the idea that it is possible to fabricate all prosthetic appliances using only one alloy. However, the properties and bonding mechanism of this system have not been clarified. In this study, the bonding characteristics of the universal alloy and its porcelain were investigated. Three systems of the universal alloy and its porcelain and two conventional porcelain fusing to metal systems were selected. The bonding strengths were measured by a shear bond test; fractured surfaces after the bond test and the interface between the alloy and the porcelain were observed using a scanning microscope and analyzed with an electric probe micro analyzer. The bonding strengths of the universal alloys ranged from 13.7 to 21.4 MPa. Moreover, porcelain segments remained on all fractured surfaces after the bond test and a tight interface between the alloy and the porcelain of the sectioned specimen was observed. The results suggested that usage of two universal alloys similar to a conventional porcelain fused to metal alloy is possible.
