How Mathematics is helping to provide for better attachment for dental crowns.  Researchers at Chalmers University of Technology are developing a new method for determining exactly how to optimally prepare a tooth to place a crown on it. The method will be able to improved quality and reliability of the crown replacements as well as result in significantly cheaper and faster dental treatment. Dentists will soon be able to benefit from a computer program being produced by a group of researchers at Chalmers, the researchers are now planning to run clinical tests. The software is based on advanced mathematical models and on state-of-the-art visualization technology
