CLOSURE OF BUCCAL-SINUS COMMUNICATION WITH L-PRF: LITERATURE REVIEW

Abstract

Oroantral communication (OAC) is a dental complication that may arise from surgical procedures in the posterior maxillary region and, if not properly managed, can progress to fistula formation or chronic sinusitis. Among the various closure techniques reported in the literature, the use of Leukocyte- and Platelet-Rich Fibrin (L-PRF) stands out as an autologous biomaterial with high potential for tissue regeneration. In this context, the present study aims to evaluate the applicability of L-PRF in the surgical closure of OAC. This work consists of a narrative literature review conducted between April and October 2025, through searches in the PubMed, Google Scholar, and SciELO databases, using the following descriptors: “oroantral communication,” “L-PRF,” and “tissue regeneration.” Studies published between 2013 and 2024 that addressed the use of L-PRF in the surgical management of OAC were included. The reviewed literature indicates that L-PRF is a safe, biocompatible, minimally invasive, and cost-effective technique, demonstrating favorable outcomes in tissue healing and a reduction in postoperative complications. It is concluded that L-PRF represents an effective and promising alternative for the closure of oroantral communication.
