WHY IS THE CTE OF GLAZE IMPORTANT?
The coefficient of thermal expansion of the glazes matches perfectly with the coefficient of thermal expansion of zirconia.
The figure above displays the percentage of linear change of the two materials obtained from a dilatometric measurement during heating from 25ºC to about 500ºC. Dilatometry is a thermo-analytical method for measuring the shrinkage or expansion of materials over a controlled temperature regime. From the results above, the curve of the glaze is slightly under the curve of the zirconia. This means that during the glazing procedure, the zirconia material expands with the increase in temperature and the glaze melts, adhering to the surface of the restoration. During cooling the glaze material follows the same speed of contraction of the zirconia providing a final glazed restoration free of thermal stress, improving mechanical bonding and eliminating the problem of delamination.
RAC glaze is the ideal material with this tailored CTE for zirconia and lithium silicate restorations.
