The pre-Sintered Co/Cr blocks are intended for use in manufacturing individually designed dental restorations, which can be polished or veneered after milling and sintering. locks comprised of cobalt-chromium alloy are used.The blocks are initially manufactured in a partially sintered state; then, enlarged by the inLab CAD/CAM system, they are individually processed to specification, and finally, densely sintered Fragment These densely sintered single-unit products are then veneered and/or polished in the usual manner following reworking. The advantages include:
The speed of the process,
The high quality of work,
The safety of the process due to wet processing,
The clean, purely digital workflow
