Comparison of compressive strength of solid and hollow pontic designs for ceramometal fixed partial dentures.
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.
