title: Periodontal considerations in tooth preparation for crowns and bridges.
abstract: Correct tooth preparation and adequate reconstruction of the anatomy of the crown are essential to the maintenance and preservation of a healthy periodontium. Adequate tooth preparation requires careful attention to many details and clear knowledge of the features of the finished product. The anatomic reconstruction of the crown with a perfect marginal adaptation will provide an adequate environment for maintaining the health of surrounding periodontal tissues.
