Soft Tissue Healing After Post-Extractive Alveolar Ridge Reconstruction Using a Magnesium Membrane-Based Regenerative...

Area of Science:

• Regenerative Dentistry
• Biomaterials Science
• Oral Surgery

Background:

• Alveolar ridge preservation is crucial for future dental implant placement.
• Resorbable barrier membranes aid ridge preservation, but evidence on magnesium-based membranes is limited.
• Soft tissue healing is a key factor in regenerative procedures.

Purpose of the Study:

• To evaluate mucosal healing after alveolar ridge reconstruction using a pure magnesium membrane (NOVAMag®).
• To assess the clinical feasibility of NOVAMag® in combination with xenogeneic bone graft and collagen dermal matrix.
• To investigate secondary outcomes including pain and quality of life.

Main Methods:

• Prospective observational pilot study in five patients.
• Alveolar ridge reconstruction using NOVAMag®, xenogeneic bone graft, and collagen dermal matrix.
• Soft tissue healing assessed via Wound Healing Index (WHI) at multiple time points.
• Postoperative pain (VAS) and oral health-related quality of life (OHIP-14) evaluated.

Main Results:

• Mean WHI scores improved from 4.4 at day 7 to 4.8 at day 14.
• Complete excellent healing (WHI 5.0) achieved by day 90 and maintained through day 180.
• One instance of partial wound dehiscence resolved without complications.
• Low and transient postoperative pain (VAS 1.86) and impact on quality of life (OHIP-14 20.8).

Conclusions:

• The NOVAMag® membrane demonstrates clinical feasibility for post-extractive alveolar ridge reconstruction.
• This regenerative approach supports effective soft tissue healing.
• Larger controlled trials are warranted to validate these preliminary findings.
