A recently released commercially available novel porcine acellular dermal matrix (PADM) appears to possess acceptable biologic and clinical properties to be considered as an acceptable soft tissue replacement material. The aim of these three case reports is to present the treatment of multiple gingival recession by means of different variations of the tunnel and PADM as well as the clinical outcomes obtained at 3 years postoperatively. The healing outcomes demonstrated only minor surgical complications, with minimal patient-reported discomfort. At 3 years postoperative, ideal functional and esthetic outcomes were observed. PADM seems to be a promising xenogeneic soft tissue substitute. Further studies with a higher number of patients and defects are necessary to confirm the present findings.
