Pcd end-mills for dental crown

Abstract

Some embodiments of the current invention include a super hard cutting tool configured for use in an existing Computer Aided Milling (CAM) machine. For example, a diamond tool may be configured to replace a Tungsten Carbide (WC) cutting tool used in an existing CAM machine. Optionally, the diamond tool may use a Polycrystalline diamond (for example a PCD tip). Optionally, the super hard tip will have the same geometry and/or substantially the same geometry as a convention WC tool. For example, the super hard tool may be used to work (e.g., mill) a green blank (e.g., non sintered zirconium). Some embodiments of the current invention include working a fully hardened dental prosthesis. For example, a super hard cutting tool may be used to work a fully hardened blank to for the prosthesis (e.g., sintered zirconium).
