چکیده

For selecting an alloy or material to be used for implant procedure, it is necessary to remember that, there is a number of factors like corrosion behavior, mechanical properties, biocompatibility and cytotoxicity, and also the availability and cost, while the aesthetic measures needed are in a second priority. The most important property is corrosion behavior as it is responsible for the continuity of the mechanical properties beside the biocompatibility and cytotoxicity caused by the corrosion products.

CORROSION BEHAVIOR OF BIOACTIVATED TITANIUM DENTAL IMPLANT USING DIFFERENT CHEMICAL METHODS

At the past, damaged tissue was removed from the body of patients. But now tissue regeneration using scaffolds and implants are used to repair the damaged tissue and organs. Besides of the mechanical properties of metallic biomaterials, they suffer from bioinertness. Using some surface treatment techniques, the bioactivity and also corrosion resistance of titanium implants could be improved. In...

Corrosion behavior of pure titanium and titanium alloys in fluoride-containing solutions.

The effects of fluoride concentrations and pH on the corrosion behavior of pure titanium, Ti-6Al-4V, Ti-6Al-7Nb alloys and a new Ti alloy adding palladium, which is expected to promote a repassivation of Ti were examined by anodic polarization and corrosion potential measurements. The amount of dissolved Ti was analyzed by inductively coupled plasma mass spectroscopy. The surface of the specime...
