dc.description.abstractAbstract: Introduction: Pneumatization of maxillary sinus towards alveolar crest due to tooth loss or horizontal-vertical resorption of alveolar bone decrease sufficient bone to place dental implants in the posterior maxillary bone. The method suggested for placing implant with a standard length is use of sinus lift surgery with autogenous bone graft or bone substitute materials.The aim of present research with split-mouth design has radiographic comparison of density and height of posterior of maxillary bone after use of Open sinus lift with and without PRF Materials and methods: In this study, which was done as clinical trial and split-mouth, 14 patients with complete or partialbilateral edentulous of the upper jaw were participated. In each case, for the sinus lift surgery of the test side, PRF was used, while in the sinus lift surgery of the other side of the same patient, no graft materials were used. After six months and before of the second surgery, CBCT were performed to evaluate bone density andheight. Results: All 41 implants had been osteointegratedand were clinically stable.It was observed that the bone height was 1.42 mm higher in the group with PRF than that group without PRF, which is statistically significant. The mean density of the bone formed around the dental implants in the PRF group was 52.85 units larger than that of the group without PRF, which was statistically significant. Conclusion: using prf in sinus lift surgerymay enhance the quantity and quality of bone formation.
