A new milling unit for an efficient workflow
Skramstad, Michael J.
Aim: This article introduces a new milling unit (Cerec Primemill, Dentsply Sirona). Clinical cases show how this new milling unit functions to improve the overall workflow of single-visit chairside dentistry.
Materials and Methods: The unit has a touchscreen that guides the user through the process of setting up the manufacturing job. This process, along with the pretouch process, is completed prior to the procedure. In addition to the guided workflow, the milling unit has a new block scanner and a radio-frequency identification (RFID) reader for bur identification/monitoring. It also has new milling tools and manufacturing algorithms and uses a unique parallel milling strategy with zirconia and a novel grinding strategy with glass-ceramic.
Results: The optimized tool geometries and manufacturing algorithms along with new mechanical and electronic components allow for an improvement in quality and speed.

Keywords: machining strategy, workflow, touch interface, color-coded cap
