Sažetak
Although dental implants have been used since ancient times, there is a continuing need to improve characteristics to ensure their long- term integration into the jaw.^1 Current trends in dental implant research are focused on surface properties modification by biomimetic and bioactive coatings that mimic architecture of the human bone and biosurrounding.^2-4 Therefore, the titanium dental implant was functionalized by two different molecules, Cholecalciferol (vitamin D3) and Alendronate sodium (Fosamax®T). D3 vitamin and Alendronate were chosen due to their known positive influences on human organism, especially on the bone-system. The aim of functionalization was (i) to improve anti-corrosion properties of the implant and simultaneously (ii) make implant´s surface potentially more bioactive (to promote and accelerate osseointegration). An integrated experimental-theoretical approach was applied to study coating´s formation mechanism, wetting properties and corrosion behaviour in an artificial saliva solution (during 7 days). In general, the results indicate improved surface properties of the implant after functionalization and are in a direct corelation with chemical nature and structure of coating molecules.
