Proven technology meets high flexibility
After milling or grinding materials like non-precious metal or zirconium oxide, a sintering process is necessary to achieve the desired material properties. And usually, restorations are stained or glazed before insertion and need firing.
Dentsply Sirona offers sintering and porcelain furnaces for a great variety of materials intended for use in dental practices and in dental labs. Be it the small and fast induction sintering furnace CEREC SpeedFire for the chairside treatment with full contour zirconia, the powerful and comfortable inLab Profire 2-in-1 sintering furnace for the dental lab or the reliable porcelain furnace Multimat Cube, our furnaces are the best choice to supplement the CEREC or inLab systems.
Dental Sintering and Porcelain Furnaces from Dentsply Sirona
Benefits
Why choose our Dental Sintering and Porcelain Furnaces?
The furnaces cover a wide range of indications
They sensibly complement the CEREC and inLab product ranges
Easy to operate touch-displays for intuitive usability
Fast heating rates
Full contour zirconia restorations in one session
CEREC SpeedFire is the smallest and fastest sintering furnace on the market and can sinter a full-contour zirconium crown in approximately 14 minutes1. The advantages of full-contour zirconia can thus be used for chairside treatment.
CEREC SpeedFire can process the Dentsply Sirona ceramic block materials as well as partner materials from Ivoclar Vivadent, VITA Zahnfabrik, 3M Dental, Kuraray Noritake Dental, GC and Shofu.
The sintering process
During sintering, fine-grained ceramic or metallic materials are heated up at a temperature below the melting temperature of the main components. The shape of the workpiece remains intact. The material condenses and shrinks. A green body is formed which solidifies by temperature. The sintered product only then gets its final properties such as hardness, strength or temperature conductivity. The sintering shrinkage is taken into account during the construction of the restoration – the workpiece is milled larger by the shrinkage factor.
