Objective: The aim of this study was to evaluate the transcrestal sinus lift using Osseodensification technique
with simultaneous implant placement. Material and Methods: In this case series 7 patients who needed
implant placement in the atrophic posterior maxilla were enrolled. In all the cases the residual bone height
between the sinus floor and the alveolar crest was 4-6 mm. Transcrestal sinus lift was performed using
Osseodensification with simultaneous implant placement. Cone-beam computed tomography (CBCT) were
obtained immediately postoperative and 6 months after operation. Implant stability using Osstell® were
assessed at the time of implant placement and implant exposure (6 months). Results: The results showed
that the mean bone height gain was 5.33±0.83mm at 6 months postoperatively. Mean bone density value
was 818.43±109.63 HU. Mean ISQ value was 80.00±3.11 at 6 months postoperatively. The duration of
surgical procedure (minutes) ranged between 25-38 minutes with an average of 30.86±4.10 minutes.
Conclusion: The crestal maxillary sinus floor elevation using Osseodensification technique with simultaneous
implant placement provide superior results regarding bone density and implant stability and less duration
of surgical procedure.
