Evaluation of the physical properties of crown dental porcelain and the effect of newly developed anti-binding additive.
A colloidal silica-based substitute for the water added to dental porcelain has been developed which restricts rounding on firing and gives greater and indefinitely prolonged unfired biscuit strength. In conjunction with product evaluation, it has been found that both the modulus of rupture and the diametrical tensile strength of dental porcelains can be measured with a high degree of precision.
