The complete-coverage restoration and the gingival sulcus

There is an interrelationship between complete coverage restorations and the gingiva. The terminal margin plays an important role in maintaining gingival health. Periodontal disease is minimal with restorations which do not invade the sulcus, but the caries attack rate, retention, or esthetic requirements may compel entry into the sulcus.The technique described in this report permits entry into the gingival sulcus without creating permanent injury. The preparation also provides adequate space for the gold collar without injury to the gingiva.
