We report on the study on the titanium-magnesium (Ti-Mg) bioactive metal-metal composite utilized for a fabrication of dental implants. The biocompatible Ti-12vol.%Mg composite, named BIACOM, is manufactured using a cost effective approach, where of Ti-Mg powder mixture is extruded at low temperatures. Microstructure of BIACOM comprises permanent Ti matrix and biodegradable Mg phase of low elasticity modulus. Compared to Ti Grade 4, the reference material used for dental implants, the properties of BIACOM include lower density and Young`s modulus, while the mechanical strength and fatigue performance of Ti Grade 4 are maintained. Presence of Mg, which dilutes in human body over the time after implantation, provides further decrease of Young`s modulus and yields enhanced macro and micro roughness at implants surface. As a result, BIACOM shows improved mechanical compatibility and better osseointegration potential.
