Soft Tissue Graft Placement Using a Porcine Acellular Dermal Matrix (PADM) and Resorbable Magnesium Fixation Screws: A Case Series.

: Adequate soft tissue thickness and keratinized mucosa are essential for the long-term health and esthetics of the peri-implant area. A porcine acellular dermal matrix (PADM) has shown promise in augmenting soft tissue, but reliable fixation remains a challenge. : This case series describes the use of a PADM fixed with resorbable magnesium screws (NOVAMag) in three patients requiring peri-implant soft tissue augmentation. The grafts were stabilized with magnesium screws on the buccal side. The clinical outcomes were evaluated over a period of 3-6 months using STL imaging and direct measurements. : All patients showed an improvement in their mucosal volume and keratinization. The mean vertical increase in soft tissue was 0.87 ± 0.16 mm and the mean horizontal increase was 1.00 ± 0.13 mm. The mucosal thickness increased from a baseline value of 1.0-1.2 mm to 1.9-2.1 mm, and the width of the keratinized mucosa improved by an average of 1.0 mm. No complications were observed, and in all cases there was tension-free healing and esthetic results. : A PADM in combination with resorbable magnesium fixation screws offers a predictable and minimally invasive solution to improve peri-implant soft tissue with favourable short-term volumetric and esthetic results.
