Use of a Double‐Layer Technique With an Acellular Dermal Matrix to Treat Miller Class I and II Gingival Recession Defects: 4‐ to 5‐Year Results

The purpose of this retrospective record review is to evaluate the long‐term performance of a double‐layer technique using an acellular dermal matrix (ADM) in conjunction with a coronally advanced flap (CAF) in treating Miller Class I and II gingival recession defects (GRDs). Case Series: A total of 26 patients with isolated Class I and II GRDs were treated. These patients were treated as part of routine clinical practice based on the individual needs of the patient. After 4 to 5 years (48 to 66 months), the mean GRD decreased from 4.0 ± 1.0 to 0.3 ± 0.6 mm. This represents 92.5% root coverage. Complete root coverage was achieved in 69.2% of the cases. Improvements were also found for probing depths and clinical attachment levels at 4 to 5 years. Conclusion: These results support the use of a double‐layer technique using an ADM in conjunction with a CAF in treating Class I and II GRDs.
