NPM CoCrMo - alloys exceed in dental technology and dentistry on account of the high mechanical and chemical durability. Only the dental spark erosion procedure enables the manufacture of all metallic elements of a dental prosthesis using only one single NPM alloy (CoCrMo). The advantages are manifold. The gold-free noble alloys are used for all types of dental prostheses - for high quality, telescopic prostheses with controllable friction and combined fixed/removable dentures with connecting attachments and latch connections as well as for dentures on implants with passive fit. Improved for spark erosive application: our nickle-free SAE Okta special alloys (CoCrMo): Okta C, Okta MVS, Okta M.
