Maxillary Sinus Augmentation Using Xenograft and Choukroun's Platelet-Rich Fibrin as Grafting Material: A Radiological Study.

Aim: The objective of the study was to assess the efficacy of xenograft (BIO-OSS) and platelet-rich fibrin in maxillary sinus augmentation using lateral window approach.

Materials And Methods: A total of 22 direct sinus lifts were done within a period of two years, and the results were analyzed using two parameters: (1) augmented bone height and (2) bone density in the maxillary sinus. Pre-operative and three-month CT scan was taken for all the 22 patients.
