USE OF PLATELET-RICH FIBRIN IN MAXILLARY SINUS LIFT

Abstract

Implant rehabilitation in the atrophic posterior maxilla often requires maxillary sinus augmentation procedures. Platelet-Rich Fibrin (PRF), an autologous platelet concentrate, has been established as a biomaterial of great interest for optimizing the regenerative process. The objective of this work was to perform a literature review, based on 19 selected articles, to analyze the clinical efficacy, indications, and current debates regarding the use of PRF in maxillary sinus floor lift surgeries. The analysis of the literature demonstrates that PRF, when used as a sole grafting material, is a predictable and cost-effective alternative, supported by long-term studies showing volumetric stability and high implant success rates. However, its benefit as an additive to other biomaterials remains controversial; the evidence does not support a significant increase in the final bone volume, although it suggests an acceleration of initial bone maturation. It is concluded that PRF is a versatile and established tool, with strong evidence for its use as an autonomous graft and in the management of complications. Its application as an additive, however, should be indicated to optimize the biology of the healing process, rather than primarily as a means to obtain greater bone volume.
