Using a collagen matrix to treat single gum recession

Functionalization of a Volume-stable Collagen Matrix (VCMX) Using Injectable Platelet Rich Fibrin (i-PRF) for the Treatment of Single Gingival Recession

Not applicable Interventional Universidade Estadual Paulista Júlio de Mesquita Filho · NCT05916742

This study is testing a new way to treat gum recession using a special collagen matrix and platelet-rich fibrin to see if it helps people heal better with less pain and fewer complications than traditional methods.

What this trial studies

This study investigates the use of a volume-stable collagen matrix biofunctionalized with injectable platelet-rich fibrin (i-PRF) as an alternative to traditional connective tissue grafts for treating single gingival recessions. The goal is to enhance the healing process while minimizing complications such as bleeding and postoperative pain. Participants will undergo a coronally advanced flap procedure combined with the collagen matrix and i-PRF to assess the effectiveness of this innovative approach. The study aims to improve patient acceptance and outcomes in periodontal surgery.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with a single gingival recession on vital canines or premolars, experiencing dentin hypersensitivity or aesthetic concerns.

Not a fit: Patients who smoke, are pregnant, or have contraindications for periodontal surgery will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a less invasive and more effective treatment option for patients with gingival recession.

How similar studies have performed: Other studies have shown promising results with similar biofunctionalized collagen matrices, indicating potential for success in this approach.
