Popis: Aims: To compare baseline residual ridge height using CBCT and panoramic radiographs. A secondary aim was to examine the magnitude of vertical bone gain 6-months following trans-crestal sinus augmentation and compare it between operators. Methods: Thirty patients, who underwent trans-crestal sinus augmentation simultaneously with dental implant placement were included in this retrospective analysis. Surgeries were done by two experienced surgeons (EM and EG) using the same surgical protocol and materials. Pre-operative residual ridge height was measured on panoramic and CBCT images. The final bone height and the magnitude of the vertical augmentation were measured on panoramic x-ray taken 6 months following surgery. Results: Mean residual ridge height measured pre-operatively using CBCT was 6.07±1.38 mm, while these same measurements on the panoramic radiographs yielded similar results (6.08±1.43 mm), which were statistically insignificant (p=0.535). Postoperative healing was uneventful in all cases. All 30 implants were successfully osseo-integrated at 6 months. The mean overall final bone height was 12.87±1.39 mm (12.61±1.21 and 13.39±1.63 mm, for operators EM & EG respectively (p=0.19). Likewise, mean post-operative bone height gain was 6.78±1.57 mm. which was 6.68±1.32 mm and 6.99±2.06 mm for operators EM and EG respectively, p=0.66. A moderate positive correlation was found between residual bone height and final bone height (r=0.43, P= 0.002). A moderate negative correlation was found between residual bone height and augmented bone height (r=-0.53, p= 0.002). Conclusion: Sinus augmentation performed trans-crestally produce consistent results with minimal inter-operator differences between experienced clinicians. Both CBCT and panoramic radiographs produced similar assessment of the pre-operative residual bone height.
