Abstract Background Gingival recession is prevalent and often treated with coronally advanced flap plus connective tissue graft (CAF+CTG). Porcine acellular dermal matrix (PADM) offers a donor‐site‐free alternative. Contemporary digital imaging allows minimally invasive, three‐dimensional (3D) soft‐tissue assessment. This case report quantified 3D soft‐tissue changes after PADM‐based root coverage using an integrated digital workflow. Methods A 38‐year‐old woman presenting with recession‐type 2 (RT2) defects on teeth #7, #6, and #5 underwent root coverage with an extended CAF in combination with a PADM. Three‐dimensional datasets were obtained at baseline, 6 months, and 12 months using intraoral scanning and cone‐beam computed tomography (CBCT). These were processed with image‐analysis software to assess volumetric and contour changes over time. Clinical parameters and patient‐reported satisfaction (visual analog scale, VAS) were also recorded. Results Buccal soft‐tissue volume increased from 329.70 mm 3 (baseline) to 454.81 mm 3 (6 months), then to 345.25 mm 3 (12 months), yielding a net gain of +4.72% versus baseline and a −24.09% reduction from the 6‐month peak. Color‐coded maps indicated predominant augmentation in the cervical third with contour stability at 12 months. VAS scores improved over time. Conclusions PADM‐assisted root coverage increased gingival thickness and resulted in a stable buccal contour. 3D CT volumetric assessment seems to be a promising method for quantifying long‐term changes in regenerated tissues.
