    • Biomechanical properties of composite compact-porous titanium produced by electric discharge sintering 

      Minko, D.; Belyavin, K.; Sheleg, V. (2017)
      The main disadvantage of currently used endosteal implants is their unsatisfactory biostable performance. Under action of functional stress caused by flaws of the design or lower mechanical characteristics the areas of stresses extreme concentration exceeding strength limits of bone tissue appears in the bone surrounding the implant that leads to the tearing away the implant.
