Comparative efficacy of autologous platelet-rich fibrin and collagen membrane on clinical outcomes following vestibuloplasty: A randomized controlled trial

PRF is advantageous in controlling immediate postoperative pain, while collagen membrane provides superior long-term wound healing and vestibular depth augmentation. Both materials are equally effective in maintaining attached gingiva width. The selection of dressing material should be guided by the clinician's primary objective-whether prioritizing postoperative comfort or enhancing regenerative outcomes.
