Supragingival Margins are preferred in restorative dentistry to maintain a healthy periodontium. However, some clinical situations, such as extensive carious lesions, esthetic demands, pre-existing deep Margin restorations, or the need for retention, lead to subgingival Margins. 1 Localized subgingival Margins can complicate adhesive restorations because of biological (biologic width violation and gingival inflammation) and operative problems (isolation, impression taking, and delivery) that hinder their durability and relationship with the periodontal tissues. 2-4 In other words, the subgingival Margins are difficult for clinicians to manage because of cavity preparation, caries removal, impression taking, isolation, overhanging problems, and the biological width (BW) violation probability. 5
