<h4>Aim</h4>In the present study, we evaluated the clinical, radiographic, and histological comparisons of completely autologous titanium-prepared platelet rich fibrin (T-PRF) or allograft in sinus-lifting procedures.<h4>Methods</h4>Eighteen posterior maxilla requiring sinus-lifting procedures using the balloon-lifting technique for implant placement were selected. Ten sinuses were randomly assigned to T-PRF as the test group and eight to allografts as the control group. After 4 and 6 months in the test and control groups, respectively, computed tomography was done, and bone samples were received during implant surgery. Three months after the second surgery, implant stability was measured.<h4>Results</h4>Radiological results showed that the allograft group had better results (62% in volume, 53% in density, and 69% in height) than the T-PRF group. Histomorphometric results showed that newly-formed bone ratios were 17.28 ± 2.53 and 16.58 ± 1.05 in the allograft group and T-PRF groups, respectively. There was no significant difference between the test and control groups (P = .611) for implant stability values.<h4>Conclusions</h4>The use of T-PRF alone in sinus-lifting operations has successful clinical and histomorphometric results. Bone formation in the T-PRF group was accelerated to 4 months compared to allografts according to the histological results.
