Precipitation hardening or solid solution strengthening-use of a biocompatible cobalt based alloy and method of making an implant or prosthesis by material removal processing

摘要

The present invention shows the possibility of applying a subtractive process to allow easy production of implants or prostheses, in particular dental implants or prostheses. To this end, the present invention proposes to use precipitation hardening or solid solution strengthening-biocompatible cobalt based alloys in the preparation of the blanks. Such blanks are provided in a flexible state in the course of the process according to the invention. Subsequently, each component (implant or prosthesis) is produced by a material removal process from a soft blank. This is followed by heat treatment of the implant or prosthesis, whose hardness is adjusted by precipitation hardening or solid solution formation.
