Abstract:

To prevent periodontal complications after esthetic rehabilitation it is essential to minimize soft tissues injury in case of subgingival ledge position. It was established that the border of ledge should not interfere with biological width of the tooth. Clinical researches showed that location of circular edge at 0.5 mm distance and more from epithelial attachment decreases the danger of periodontal tissues inflammatory response. From the clinical point of view the main factor determining subgingival level of preparation is an adequate assessment of gingival groove depth. This assessment is however complicated by the variations of morphometric features of biological width causing inaccuracy of subgingival border preparation and leading to undesirable effects in periodontal tissues (gingivitis, periodontitis, recession).
