Niobium based coatings for dental implants

▶ The coatings of niobium oxide and niobium nitride improve the corrosion resistance of stainless steel. ▶ The niobium oxide and niobium nitride coatings increase cell proliferation. ▶ The niobium-based coatings do not have a toxic effect on cells. ▶ The niobium nitride coatings show better cell adhesion than the uncoated stainless steel. ▶ The niobium-based coatings have a similar biocompatibility to titanium.
