Chemists from the Otto-Schott-Institute for Glass Chemistry at Jena University in Germany have produced a new kind of glass ceramic with a nanocrystalline structure. The material has high strength characteristics and optical properties which make it ideal for use in dental applications.
The ceramic material comprises magnesium, aluminum and silicon dioxide, a combination known for its high strength properties. So far the new material has demonstrated a strength five times greater than comparable denture ceramics. By making the ceramic optically similar to natural teeth the researchers have overcome the major barrier for use of the material in dental applications.
