Abstract
A system for continuous production of prosthodontic pieces such as crown cores, crowns or the like is provided. The system utilizes turning and milling on a live center CNC machine of a rod stock of material for making the pieces such as Bio-HIP Y-TZP (High Heat and Isostatic Pressure formed ytrium stabilized zirconium dioxide) that is automatically feed into the machine. Multiple pieces are cut one after another from the continuous rod stock. The machine includes a an engraving unit that marks pieces after they are cut with an identification mark such as a certification mark and/or an identification code. In one embodiment, multiple machines are utilized in which each machine is fed a rod stock of a different shape and/or size. A central control unit obtains Cad/Cam specifications for a piece that is to be cut and selects the machine on which the piece is to be made by determining the rod stock that will require the least amount of cutting.
