Figure Lengend Snippet: Figure 5. Mini-flap: (a) Preoperative photo showing tooth #5 MOD amal- gam restoration with a deep mesial subgingival margin. Temporary resto- ration in occlusal surface is where endodontic access was prepared. (b) Radiograph of tooth #5 shows suc- cessful endodontic treatment. Mesial margin approximates osseous crest. (c) Facial-lingual mini-flap. Tissue retraction is limited to the keratinized tissue but provides excellent access to mesial restoration margin. (d) Op- erative field isolated with rubber dam. Note that despite location of deep mesial margin and execution of mini- flap the rubber dam provides com- plete isolation and accessibility of what once was the deep subgingival margin. (e) Amalgam build-up com- pleted; single suture placed in inter- dental papilla.

Article Snippet: The use of special matrices may facilitate the restoration of these complex situations, and special matrix bands are available with cervical extensions (eg, Tofflemire matrix band #2 [Produits Dentaire SA, Vevey, Switzerland] or Contact Matrix Subgingival matrices [Danville Materials, San Ramon, CA]).
