For biocompatibility we mean being in tune with the surrounding biological tissues or the ability of a material to induce an appropriate biological response in a specific application. This implies an interaction between the host environment (the patient), the material and the function to be played by the material itself.
To conclude the biocompatibility is not an intrinsic property of the material but a characteristic of the material itself that interacts with the host environment for a specific function.
The titanium dental implants, for example, represent a clear example, in fact, thanks to the properties of titanium implants, when properly positioned, can be osteointegrated or come into intimate union with the surrounding bone.
The other commonly used prosthetic materials are:
- ALLOYS FOR METAL / CERAMIC;
- RESINS FOR TOTAL PROSTHESIS;
- RESIN AND CEMENT COMPOSITES.
What is zirconia?
The zirconia (zirconium oxide) is a ceramic oxide which comes as a white powder. After industrial processing and sintering in dedicated furnaces achieves high mechanical properties that allow it to be used in dentistry for the construction of prosthetic substructures or for the fabrication of restorations entirely zirconia. Where indicated, completely replaces the use of metal alloys. The zirconia used in dentistry is stabilized with yttrium which gives it a very high chemical stability (Y-TZP).
Zirconia is biocompatible?
As all ceramic materials, zirconia is a biocompatible material. The aging of the zirconia is not linked to the biocompatibility or the corrosion of the material, but the deterioration that can occur after many years in an aqueous environment. However, this phenomenon has not been found to date in dentistry because the zirconia used is stable in the tetragonal crystalline form thanks to the use of stabilizers. Clinical data in the short-term average confirm its stability.
How can patients assess the quality of the materials of their restorations?
Italian L'odontotecnica stands as excellence recognized internationally, thanks to the interpretation of our style and our culture.
Although current construction techniques prosthetic make use of modern computer-assisted technology, the production process in the majority of Italian laboratories is still artisanal, ensuring l'individualità and the uniqueness of each individual artifact, thus achieving optimal aesthetic and functional results with the full satisfaction of patients.
An important point to be able to get quality dentures is the use of selected materials and certificates. L'odontotecnico Italian as the manufacturer is obliged to ensure that the prosthesis is performed in accordance with applicable laws, the strategy must comply with these directives (93/42 EEC) drafting certified documents for every single production. EU Directive 93/42 EEC came into force in 1997 regulates Stylus on the market and putting into service in the Community, of medical devices (implants) carried out with bearing CE marking materials.
