Definitions

  • Biomaterial has been very laborious and difficult. So much so, that until March 1986 the definition of "Biomaterial” was not approved.
  • Biomaterial is understood as a non-living material used in a medical device and designed to interact with biological systems.
  • the implantation of a biomaterial carries with it an injury in living tissues, reacting these against the lesion, its first reaction being an inflammation, which will be followed by a reparative process and finally healing of the incision.
  • Biomaterials can be classified according to their chemical composition into: metals, polymers, ceramics and composites or composites. Within the ceramic materials we find another classification: bioactive ceramics, bioabsorbable ceramics and bioinert ceramics (Alumina-Zirconia Composite Materials for Biomedical Applications. Doctoral Thesis of Dr. Carambás Pulgar ⁇ n, La Plata, Argentina, 2014).
  • zirconia or zirconia is understood interchangeably with zirconium oxide or Zr0 2 , white in color, insoluble in water and very refractory. When heated in certain conditions, it emits a white and intense light.
  • the process object of the present invention as well as the directly obtained product has the advantages that it is not a coating, but what is done is a stripping of the surface of the mass of the material, leaving the alumina perfectly adhered to the mass (or "bulk” in English) thus avoiding the consequent stripping or delamination of the final product and presenting an optimal nanorugosidad which favors the use of the product as a prosthesis or bone implant (see figures 1, 2 and 5).
  • the method comprises an additional step (c.1) of dissolving the YF 3 crystals by immersing the ceramic material in a 37% HCI solution. in weigh.
  • the method comprises an additional step (c.1) of dissolving the YF 3 crystals by immersing the ceramic material in a solution of H 2 S0 4 30% by weight.
  • a ceramic material obtained by the aforementioned process having a zirconia-free surface is an object of the present invention.
