sintering procedure results in approximately 25% shrinkage that has to be compensated in the milling procedure, and it may degrade the degree of adaptation of the prostheses to the abutment , which can be responsible for the above-stated clinical problems. Recently, a tough and strong material, Ce-TZP/A, has been developed .
3.1 Description of the furnace Technical description Description of the furnace The inLab Profire high-temperature furnace is used for processing sinterable ceramics and cobalt-chromium. The product to be sintered is placed in the sintering tray and positioned on the bearing plate.
Sep 09, 2015 · Furnace calibration is very important to how your restorations fit. In fact they way we calibrate our S1 Furnace is to sinter a zirconia ring and measure it with a micrometer, depending on the amount that it shrinks we increase/decrease the calibration value in the furnace. Voltage/amperage drops will also effect the way your furnace performs.
