L-PRF as a filling material in maxillary sinus floor elevation: an evaluation of viability and literature review

Abstract

The maxillary sinus is a pneumatized cavity with a pyramidal shape located bilaterally in the maxillary region. The loss of teeth in the posterior maxilla can lead to functional and aesthetic damage, commonly caused by bone resorption and subsequent remodeling, as well as limited vertical bone height. For the rehabilitation of this region, surgical procedures for bone augmentation have been implemented, such as the Maxillary Sinus Floor Lift (LASM) technique and bone regeneration. Given the relevance of the topic, this study aims to verify the limitations of using autogenous grafts, analyze the benefits of using L-PRF as a grafting material, verifying its relationship with tissue repair in maxillary sinus lift procedures, and present data on bone neoformation and speed of post-surgical recovery. For the selection of articles used in this literature review, a search was conducted for works published in journals indexed in the PubMed/MEDLINE, Cochrane Library, and Google Scholar databases, as well as a manual search for citations in the initially selected publications. The search terms used were: "platelet-rich fibrin" and "maxillary sinus floor elevation," in advanced search mode, for the period 2007 to 2024. The use of L-PRF in the LASM technique contributes to better clinical results, promoting bone regeneration safely and efficiently, making its adoption a valuable alternative in Implantology procedures.
