An investigation into the role of porcelain thickness in determining the load-carrying capacity of porcelain laminates.
The effect of specimen thickness on the strength of dental porcelain has been investigated. It has been shown that for core, dentine and combinations of these porcelains, the shell strength decreases with increasing thickness. Consequently, the load carrying capacity does not increase as much as might be expected with thicker sections. Possible reasons for this phenomenon and methods of limiting this effect are discussed.
