additive manufacturing of new generation PFMs, the metal frame is fabricated using CAD files by sintering special Co-Cr-Mb-based powder layer by layer. This wonder alloy is extremely biocompatible.
It has incredibly thin margins in comparison with conventional PFM. The CAD process detects and eliminates undercut up to 0.2 mm and the CAM process facilitates equal space for ceramic binding and avoids ceramic chip off. The long span bridges up to 16 units can be fabricated and also the high precision allows easy crown fixing, the fabrication of long span bridges through sintering eliminates rocking.
