Introduction: Dental implant therapy in the posterior maxilla may be difficult owing to limited bone height after dental extraction with sinus pneumatization. Several approaches for sinus floor elevation have been documented, and hence flapless transcrestal sinus floor elevation is minimally invasive technique which is used in moderately defected maxilla.
Objectives: Evaluate both clinical and radiographic outcomes in sinus floor elevation in transcrestal sinus lift approach with Titanium platelet rich fibrin (T-PRF) as a sole sinus graft material compared to Platelet rich fibrin (PRF).
Materials and Methods: This study was designed as randomized controlled clinical trial conducted between March 15, 2022 and February 5, 2023. 16 patients were randomly allocated into two groups: in the study group 8 patients underwent flapless transcrestal sinus lift with simultaneous implant placement using T-PRF as a grafting material, while in the control group 8 patients had PRF as a grafting material.
Clinical outcomes including assessment of patient's post-operative pain, swelling, primary and secondary implant stability were recorded on different time points. Radiographical assessment was conducted using Cone beam computed tomography (CBCT) to measure residual bone height (RBH), bone density, and sinus bone gain (SBG).
Results: No significant difference found regarding postoperative pain, edema, and nasal
bleeding. The mean of primary implant stability in study group was 58.63±5.68 while in the
control group was 54.5±6.41. No correlation between SBG and the use of T-PRF (P value = 0.389).
