Albumin-PRF in Sinus Lift With Implants: 2-Year Study

Albumin Platelet-Rich Fibrin in Lateral Sinus Floor Augmentation With Simultaneous Implant Placement: A Prospective Two-Year Follow-Up Study

thirty-two implants will be inserted in patients seeking implantation of their lost posterior maxillary teeth (premolar and molars) with limited bone height below the floor of the maxillary sinus, secondary to sinus pneumatization. The patients will be selected from those attending the outpatient clinic of the Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University.
