[Effects of the mode of ceramization on the compressive strength of Dicor crowns. A laboratory study]

The critical compressive strength of cast glass-ceramic samples with a standardised shape was evaluated as a function of the ceramization temperature. The maximum critical compressive stress was obtained under conditions prescribed by the manufacturer. After under- and overceramization by only 6 degrees C, as well as after repeated ceramization, the critical compressive strength was decreased significantly (p less than or equal to 0.05) by about 13-24%.
