A shear testing method was devised to study and evaluate the effect of various and repeated firing cycles, types of alloy, and brand of porcelain relative to the color and bond strength of ceramometal complexes specifically at the opaque porcelain-metal interface and the opaque-body porcelain juncture. Two alloys and two porcelain brands were chosen on the basis of their widespread clinical use and the marked contrast between them. An increase of the firing temperature significantly raised the bond strength for all alloy-porcelain combinations.
设计了一种剪切测试方法,以研究和评估不同的重复烧制周期、合金类型和瓷粉品牌对烤瓷复合体颜色和粘结强度的影响,特别是在不透明瓷-金属界面和不透明体瓷交界处。根据两种合金和两种瓷粉在临床上的广泛应用以及它们之间的显著差异进行选择。对于所有合金-瓷粉组合,烧制温度的升高均显著提高了粘结强度。
