Opinions have changed from the assumption that only poor restorative treatment leads to periodontal disease. Presently, it is believed that even clinically sound restorations may be an important etiological factor in the initiation of periodontal disease. The two aspects which are probably most intimately related to the supporting tissues are the manner in which the restoration establishes marginal contact with the tooth and the external contour of the restoration. In this paper, the objectives of margin placement will be reviewed; features of variously proposed designs will be compared and contrasted in the light of current materials and techniques.
