    2016-12-1 · Great concerns were raised in the early 1990´s about the use of zirconia ceramics for medical and dental applications because of these radioactive impurities and their effect on human body. However, after purifying procedures, zirconia powders with low radioactivity (<100 Gyh −1) can be achieved . These values are below the European radiation limits accepted for human body external exposure or for local internal exposure of organs and tissues and so near to those of alumina ceramics …

  • Principles and phenomena of bioengineering with

    2007-1-1 · Restorative dental materials are mainly used to fabricate dental inlays, crowns, bridges and veneers. The most suitable materials for these applications include porcelain, glasses, sintered ceramics (Mc Lean, 1 O’Brien 2) and glass-ceramics as well as inorganic–organic composites. Because glass-ceramics are capable of combining many different properties, these materials are widely used today.
