Q4: What is the recommended sintering process for these zirconia blocks?
To ensure the optimal strength and translucency of 4D Pro Multilayer Zirconia Blocks, it is crucial to follow a precise sintering process. The recommended sintering process includes:
Pre-sintering (for milled restorations):After milling the restoration from the zirconia block, the restoration should be placed into the furnace for pre-sintering at lower temperatures. This helps remove any stress from the milling process and prepares the material for final sintering.
Final sintering:The final sintering is done at temperatures between 1,450°C and 1,550°C. The specific temperature and sintering time may vary based on the size and type of restoration, but the process generally lasts between 7-10 hours.
Slow ramping of temperatures:For optimal results, it’s essential to gradually increase and decrease the furnace temperature to avoid thermal shock, which could compromise the integrity of the material.
Cooling process:After sintering, allow the restoration to cool naturally within the furnace. Rapid cooling can cause cracks or weaken the material.
