Thermal gradients and residual stresses in veneered YTZP

Objectives The occurrence of chipping of allceramic restorations with YTZP frameworks has resulted in various designs and cooling procedures recommended for reducing such behavior In this paper the temperature gradients during fast and slow cooling for conventional and anatomical designs are compared as well as an optical procedure to directly compare the influence of

Influence of cooling rate on residual stresses and

Cohesive failure of veneering porcelain or chipping has been recognised as the main disadvantage of zirconiabased restorations This is believed to be due to a propensity to develop large thermal gradients within the veneering porcelain layer when the restoration cools from the sintering temperature to room temperature

Information Moissanite New Zealand

The fire brilliance and sparkle that are so characteristic of moissanite is due to its high refractive index of 242 The higher the refractive index of a gemstone the more fire it emits Measuring moissanite’s fire of 0104 it is more than twice that of a diamond which measures 0044 Simply when comparing them side by side moissanite
