Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests a new, less invasive way to place dental implants in the upper jaw when there isn't enough bone. Instead of using a bone graft, the surgeon gently lifts the sinus membrane and places the implant at the same time. The goal is to see if new bone grows around the implant and if the implant stays secure over time. The trial will include 20 adults with missing upper back teeth and limited bone height.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Procedure: graftless transcrestal sinus membrane elevation with simultaneous dental implant placement
What this could lead to
If successful, this could offer a simpler, less invasive dental implant option for people with low bone in the upper jaw, avoiding the need for bone grafts.
What could go wrong
This is a very small early trial with only 20 participants, so results may not apply to everyone. The procedure may fail to form enough new bone or implants may not stay stable.
