title: Alterations on crown contour--effect on gingival health in man.
abstract: The effect of different supragingival crown contour on the surrounding marginal gingiva was studied on four patients. All the subjects had caries, esthetic problems, and minimal periodontal problems. Each patient received two splints; one side was overcontoured, and the other side undercontoured. The splints were observed at regular intervals within a 4-month period. The result of this study suggested that factors other than variation in supragingival crown contour in the range of +/- 1 mm determined gingival response within the first 4 months in patients with a predominately healthy periodontal structure.
