About this work
Design patented by Dr C H Mack. A dowel was attached firmly to a root before the crown was fixed to the tooth. The porcelain cavity was filled with plastic, which anchored the tooth when mounted. (Fig. 5) The gold shell or telescope tooth crown, patented by Dr W N Morrison was fixed to the natural tooth.
