Can a simple abutment preserve bone and gums after tooth extraction?
NCT ID NCT07748494
First seen Aug 05, 2026 · Last updated Sep 16, 2026 · Updated 3 times
Summary
This trial investigates whether using a socket sealing abutment, with or without bone graft material, helps preserve bone and soft tissue after immediate molar implant placement. Adults aged 18-45 with non-restorable molars will receive the implant right after extraction, and their healing will be tracked over six months using 3D scans and implant stability tests. The goal is to see if this technique improves gum and bone outcomes compared to not using grafting material.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Socket sealing abutment with or without bone grafting material
- What this could lead to
- If successful, this approach could improve bone and gum healing around dental implants placed right after tooth extraction, potentially reducing the need for additional grafting procedures.
- What could go wrong
- This is a small, early-stage study with only 20 participants, so results may not apply broadly. There is also a risk that the abutment or grafting may not provide significant benefits over standard care.
