Elementary characterization of Ti metal alloys used in implant dentistry
Brazilian Journal of Radiation Sciences, 2019 The main goal of present work is analytical characterization of standard dental implants broadly used by Brazilian dentists. An ideal biological alloy for dental implants must have very high biocompatibility, which means that such material should not ...
