Double‐Layer Technique Using an Acellular Dermal Matrix and Coronally Advanced Flap to Treat a Mandibular Incisor with a Cairo RT2 Defect: 8.5‐Year Results

Introduction The purpose of this case report is to document the 8.5 years result of treatment of a mandibular incisor having a buccal Cairo Recession Type 2 (RT2) gingival recession defect (GRD) using a double‐layer technique using an acellular dermal matrix (ADM) with a coronally advanced flap (CAF). To the author's knowledge, no long‐term results of this treatment modality in the mandibular incisor area have been reported. Case Presentation A 65‐year‐old non‐smoking female presented with an RT2 GRD on the buccal aspect of tooth #25 (International Standards Organization, ISO #41). Her overall periodontal status was healthy. This GRD was treated using a double‐layer of an ADM with a CAF. Tension‐free flap advancement was permitted by eliminating a frenum pull. Improved root coverage and stable gingival margins were found after 8.5 years. Conclusion This report provides evidence to support the use of a double‐layer technique using an ADM with a CAF to treat a mandibular incisor with an RT2 GRD.
