Management of the gingival sulcus in fixed prosthodontics: a literature review and treatment protocol.

This review of the fixed prosthodontics and periodontology literature illustrates the influence of various factors on the health of the periodontium during and after fixed prosthodontic treatment. This article describes four categories of marginal finish lines for fixed prosthodontic restorations relative to the gingival margin and the epithelial attachment. The management of each category from both the periodontal and prosthodontic prespectives is also discussed.
