Radiographic Changes in the Maxillary Sinus Following Closed Sinus Augmentation With Leukocyte Platelet Rich Fibrin

Prior to surgery, a detailed radiographic assessment is performed utilizing a limited volume CBCT and periapical radiographs (PA). During the implant planning phase, a careful evaluation of the implant's positioning and angulation will be conducted based on the preoperative CBCT images. On the day of the surgical appointment, following local anesthetic administration, a full-thickness flap is elevated, facilitating access and visibility for a comprehensive assessment of the alveolar ridge and the specific site designated for implant placement. A closed sinus augmentation will be performed. Upon completion of the infracture of the sinus floor, L-PRF will be introduced into the osteotomy and precisely propelled into the sinus. Implants placement will follow placement of the L-PRF.
