ABSTRACT: This paper documents a marsupialized dentigerous cyst associated with an amalgam. The surgical challenge was removing the amalgam from the cystic lining with zero visibility. To achieve this, the surgical procedure was computer assisted and used 3D images. Distances between the amalgam and various anatomical landmarks were assessed in order to define a path from the top of the ridge to the amalgam. The path was reconstructed at the surgical site and the amalgam removed by suction. Orthodontic treatment was associated with surgery. Three dimensional imaging is a useful procedure for deciding on the type of surgical technique likely to minimize trauma. This report is also a contribution to the literature by reporting two dentigerous cysts associated with amalgam.
