Several approaches have been used in order to regenerate bone in the upper jaw in case of insufficient alveolar bone height for implant placement. However, new emerging techniques need to be assessed and compared to conventional methods in order to define their potential indications.
The purpose of the present randomized controlled clinical trial was to compare the clinical outcomes of two sinus floor elevation techniques: conventional lateral window technique versus a novel transalveolar approach using hydrodynamic ultrasonic device.

| Sinus floor elevation using an ultrasonic device |
| Measure | Description | Time Frame |
|---|---|---|
| Sinus membrane perforation | Presence/absence of sinus membrane perforation during the surgery | During the surgery (from beginning to end) |

| Hematoma | Presence/absence of hematoma postoperatively | From the end of surgery up to 1 week postoperatively |
| Postsurgical bleeding | Presence/absence of bleeding postoperatively | From the end of surgery up to 1 week postoperatively |
| Nasal discharge | Presence/absence of nasal discharge postoperatively | From the end of surgery up to 1 week postoperatively |
| NSAID consumption | Quantification of NSAID consumption per day up to 1 week postoperatively (tablets/per day) | From the end of surgery up to 1 week postoperatively |
| Patient related outcome measures (PROMs) |
| Measure | Description | Time Frame |
|---|---|---|
| Radiographic outcomes | Radiographic (CBCT) qualitative assessment of the gained volume (change in volume from baseline to 1 year postoperatively). | From the baseline (surgery procedure) up to 1 year post-surgery |
| Implant survival rates |

PROMs were assessed with a questionnaire using a visual analogue scale (VAS), which was given to all participants in order to assess their perception before, during, and after the intervention. A graduated scale from 0 to 10 was used, with a lower score presenting a better outcome. |

Implant survival rates assessment at 1 year postoperatively.
