Repairing the ditched amalgam.

Fractured or ditched margins are the most common problem associated with amalgam restorations. Unfortunately, continuously replacing dental amalgams takes its toll on a tooth. Good restorative practices demand that we limit the number of restorative procedures to which we subject a tooth. This paper looks at an effective technique for sealing the margins of ditched amalgam restorations. This technique allows the practitioner to repair the ditched area of the amalgam without replacing the amalgam restoration.
