Abstract

Introduction: Rehabilitation of patients with atrophic maxilla represents one of the greatest challenges in contemporary implant dentistry, since progressive bone resorption resulting from prolonged tooth loss compromises the volume and bone density necessary for rehabilitative treatment. Guided Bone Regeneration (GBR) associated with Platelet-Rich Fibrin (L-PRF) emerges as a biologically grounded approach, capable of promoting significant bone gain and favoring tissue healing through the gradual release of growth factors, creating a microenvironment favorable to bone neoformation in severely atrophic alveolar ridges. Objective: To report a clinical case of reconstruction of an atrophic maxilla using the association between GBR and L-PRF, systematically describing the surgical treatment sequence, the biomaterials used, and the clinical results obtained throughout the postoperative follow-up. Case report: A 52-year-old male patient with total edentulism in the maxilla and severely atrophic alveolar ridge underwent a bone reconstruction protocol using guided bone regeneration (GBR) with deproteinized bovine xenograft associated with L-PRF and a resorbable collagen membrane. The healing process proceeded without complications, with no dehiscence, membrane exposure, or graft infection at any of the follow-up appointments. The patient is currently in the postoperative follow-up phase, awaiting a control cone-beam computed tomography scan scheduled for six months after the procedure, which is expected to confirm an average bone gain of between 5 and 7 mm in height and between 3.0 and 4.5 mm in vestibulolingual thickness along the reconstructed maxillary arch. Conclusion: The association between GBR and L-PRF proved to be a viable, safe, and promising approach in the reconstruction of the atrophic maxilla, with favorable postoperative clinical evolution and prospects for significant bone gain to be confirmed by pending follow-up examinations. It should be noted that the results described are limited to the case presented, and studies with a larger sample size are necessary for the consolidation of this protocol.
