Abstract
A total of 60 ceramometal frameworks were subjected to compressive loading. Half of the specimens had a hollow pontic design. After the addition of porcelain, it was found that there was no significant difference in the fracture resistance of the porcelain whether the pontic was solid or hollow.
摘要
总共60个烤瓷熔附金属支架承受压缩载荷。一半的标本采用中空桥体设计。添加瓷后发现，无论桥体是实心还是空心，瓷的抗折性均无显著差异。
