Zirconia dental implants

Osseous and dental tissues present similar proprieties that justify the use of biomaterials with resemblant proprieties in surgery. The first biomaterials used in dental implantology were only metallic alloys, noble or not. The main difficulties related to the use of metals as biomaterials derive from the great difference existent between their mechanical properties and those of tissues they replace, and, on the other hand from the greater or lesser degree of corrosion in contact with the surrounding living environment, which is aggressive thorough content in water, cells, proteins and enzymes. The corrosion products of different metals and alloys can be very toxic for the host, acting locally or at distance. Titanium-based alloys, due to their good resistance at corrosion and also to their important mechanical resistance, are the most commonly used nowadays. In order to increase the compatibility of these alloys, different techniques of covering their surface with other materials with better compatibility have been created.
