Abstract
Guided bone regeneration (GBR) is a well-established method to augment the alveolar bone before or during implant placement. Tension-free primary closure of the flap is a critical requirement for the success of GBR, and failure to achieve it can lead to numerous complications, including wound infections, membrane exposure, and graft loss. Periosteal-releasing incision (PRI) is a straightforward and predictable flap advancement method that achieves tension-free flap closure in bone augmentation procedures such as GBR. In this method, the mucoperiosteal flap is elevated beyond the mucogingival junction, and then a PRI is made in the area apical to the mucogingival junction from distal to mesial. Complications like swelling, hematoma, lingual and mental nerve injury, and reduction of vestibular depth are reported for PRI. Modifications of this technique are proposed to improve efficiency and reduce associated complications. This narrative review aims to evaluate the PRI technique and its modifications, with the goal of better understanding these methods and their proper application to achieve successful surgical treatment outcomes.
