title: Modifications of the impression to prevent cast breakage.
abstract: Broken teeth on a diagnostic or master cast, which usually occurs during separation from the impression, is a common problem experienced by dentists. This article aids in diagnosing and modifying noncritical areas of the impression to prevent this problem. One advantage of this method is that casts of periodontally involved teeth can be prevented from breaking. Disadvantages include time involved in modification and loss of noncritical areas of the tooth.
