Evaluation of Implant Stability Following Maxillary Sinus Floor Elevation Through Piezoelectric Trans-crestal Approach Versus Crestal Implant Approach
26 participantsStarted 2026-03-01
Plain-language summary
Rehabilitation of the maxillary posterior region is a challenge in every-day clinical practice. Following extraction of maxillary molars, alveolar ridge atrophy along with maxillary sinus pneumatization decrease the bone volume and increase implant placement complexity (Lyu et al., 2023). Several surgical procedures have been proposed to overcome these complications, including; short implants (Bechara et al., 2017), tilted implants (Meng and Zhang, 2022) as well as different sinus floor elevation techniques (Irinakis, 2011, Bishbish et al., 2023, Dragonas et al., 2023). Crestal maxillary sinus floor elevation has been considered a predictable and less invasive approach, providing sufficient vertical ridge height with high rates of implant survival (Guruprasad et al., 2024). However, there's limited body of evidence comparing the efficacy of different trans-crestal approaches as PISE and crestal implant approach with no bone graft. Thus, further clinical trials are recommended to determine whether the adjunctive use of piezoelectric instrumentation in internal sinus elevation offers significant clinical advantages over the crestal implant approach.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
