Ceramill Sintron

Ceramill Sintron is a chrome cobalt alloy that does not require wet milling; it can be milled using small machines designed for milling soft material. The consistency of raw material allows increases to milling speed and thus reduces the total production time.
Its framework is very similar to zirconium oxide, but raw zirconium is a bit harder, allows the use of smaller working tools, and thus warrants a perfect, more precise finish than traditional chrome cobalt. The subsequent processing of the construction is very simple. Sintering occurs in the protective atmosphere of argon at a temperature of 1250 degrees for 6 hours. Finally, the sintered construction is sand blasted.
No oxidation is required.
The only limitations bound to Ceramill sintron is contraindications relating to implants and large bridgeworks.
