Due to the well characterized level of biologicalresponse exhibited by this alloy, it has been used as a controlmaterial in Practice F 981.X2

33、.2 No known surgical implant material has ever beenshown to be completely free of adverse reactions in the humanbody. However, long term clinical experience has shown anacceptable level of biological response can be expected, if thematerial is used in appropriate applicationsREFERENCES(1) Gaechter,
