title: Using ultrasonic scalers to remove fractured root posts.
abstract: The removal of an existing cast or cemented stainless steel post has proved difficult, time consuming, and to require excessive removal of tooth structure. The use of the ultrasonic scaler alone and in combination with other techniques provides a conservative, efficient method for retrieval of broken posts from root canal spaces. The primary advantage of these techniques in the removal of posts is the conservation of remaining tooth structure.
