ADVANCED PRESSTM WITH PATENTED PROGRAMS FOR PROCESSING LITHIUM-DISILICATE CERAMICS.

Lithium Disilicate Lithium disilicate ceramics are an increasingly popular material for fabricating restorations in dental laboratories. They are characterized by their high strength and can be processed not only by CAD/CAM but also by a pressing technique similar to the one used with traditional pressable ceramics. However, the resulting quality of pressing Lthium Disilicate has varied greatly. Due to it's sensitivity to temperature while in contact with phosphate-bonded compounds common among investments.

Differences on the order of 30°C–50°C – depending on the size of the ring and the conductivity of the investment compound – pose an obstacle to consistent pressing outcomes. If more energy is briefly supplied to the ring, however, its outside temperature will rise to...

Firing chamber Ring Centre of the ring Pressure mathematical Standard pressing Muffel außen Muffel Kern/Keramik Hardly any differences exist between the program cycles used in different types of furnaces when it comes to pressing ceramics. Laboratory technicians generally assume that the temperatures inside the furnace and in the inner regions of the ring will be the same once a predefined exposure time has elapsed. However, this assumption is incorrect and easily explained. The thermocouple inside the furnace only captures the temperature in the furnace chamber, which the system attempts to...
