Nanoparticles are becoming more widely used in medicine, dentistry, pharmacy and as food additives. The aim of this work was to highlight some aspects in applying titanium and its alloys in dental restorations. Both medical and dental implant surgeons despite of huge efforts in using biocompatible materials face some challenging issues on complications which might appear even when using as inert metals as titanium. These problems may develop due to the penetration of aluminium and vanadium ions, found in negligible quantities in the implant alloys, into the body tissues. Failures in placing titanium implant can be caused by galvanic or electrochemical corrosion in the oral cavity due to release of titanium ions into the neighbouring tissues. Other possible failures in implant placement may develop due to bacterial contamination, and the development of implant inflammatory reaction supported by presence of macrophages may lead to implant rejection and loss. Released titanium ions inhibit the growth of hydroxyapatites. During corroding process metal ions or corrosion products penetrate body tissues and enter the body cells. Their local activity is known as ’metallosis’. From the biological point of view this results in tissue damage. Another possible adverse effect that might be caused by metal implants and their corrosion is allergic reactions. Side effects are rare as physical and chemical properties of titanium, first and foremost, its biocompatibility, define it as s recommended material to use in oral surgery, endodontics, prosthetics and orthodontics.
