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

Area of Science:

• Periodontology
• Dental Implantology
• Biomaterials Science

Background:

• Adequate soft tissue thickness and keratinized mucosa are crucial for peri-implant health and aesthetics.
• Porcine acellular dermal matrix (PADM) shows potential for soft tissue augmentation, but fixation is challenging.

Purpose of the Study:

• To evaluate the efficacy of PADM fixed with resorbable magnesium screws for peri-implant soft tissue augmentation.

Main Methods:

• A case series involving three patients undergoing peri-implant soft tissue augmentation.
• PADM grafts were stabilized using resorbable magnesium screws (NOVAMag®).
• Clinical outcomes were assessed over 3-6 months via STL imaging and direct measurements.

Main Results:

• All patients demonstrated improved mucosal volume and keratinization.
• Mean vertical soft tissue increase was 0.87 ± 0.16 mm; mean horizontal increase was 1.00 ± 0.13 mm.
• Mucosal thickness increased from 1.0-1.2 mm to 1.9-2.1 mm, with an average 1.0 mm gain in keratinized mucosa width.

Conclusions:

• PADM with resorbable magnesium screws provides a predictable, minimally invasive solution for peri-implant soft tissue enhancement.
• Favorable short-term volumetric and esthetic outcomes were observed.
• No complications were reported, with tension-free healing achieved in all cases.
