ANTIBACT - Long term antibacterial protected dental implants

Israel Romania

The proposed project is focused on the manufacturing of a new advanced, market oriented product, an activated and long term antibacterial protected dental implant, by integrated technologies, which starts with a new titanium bioalloy (Ti-Zr) synthesis and thermo-mechanical processing, the machining for the implant obtaining, electrochemical surface activation and long term antibacterial coating. The originality and innovation of the proposed project consists in the combined approach of the three most recent research tendencies in the dental implants field, referring to new biomaterials with non-toxic elements, oxidized bio-activated surfaces and antibacterial coatings. The project outcome is a new dental implant with non-toxic and non-allergic properties, good mechanical, bioactive and ossteointegration characteristics and long term antibacterial activity, compared with the short time antibacterial resistance given by the antimicrobial coatings in use on commercial scale. The project has an original approach regarding the obtaining and characterization methods.
