Abstract:
All contours of the restoration not directly related to occlusion are related to the gingival tissues only. And proper contour of restoration is essential for the health of the periodontal tissues. But there are so many controversies about the contour of the restoration, and there is no uniform agreement in the literature as to which contour of restoration is best for periodontium. In general, the contour of restoration means the supragingival contour only but in the case of the intracrevicular restorative procedure the subgingival contour of restoration must be considered. Because a portion of the restoration is placed in a gingival sulcus which is extremely vulnerable to periodontal disease. In this article the concepts or theories of the supragingival contour, the subgingival contour, and the emergence profile were discussed. The contour of the restoration and the biotype of the periodontium must be considered in intracrevicular restorative procedure. And sufficient tooth preparation is important factor to develop the proper contour of restoration which is kind to periodontium.
