PMMA BLANK
PMMA blank is the best temporary restorations material For CAD/CAM
dental system, It's made of Polymethylmethacrylate, With properties
of higher strength, better biocompatibility, preferable appearance,
etc. And PMMA blank is superior in low cost and it could be easy
machined by share with the ceramics blank.
