Which implant technique better preserves bone and gums?
NCT ID NCT05946954
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial compares two methods for placing a dental implant immediately after tooth extraction in people with a specific bone defect (labial plate dehiscence). The two techniques are Immediate Dentoalveolar Restoration (IDR) and the Ice Cream Cone technique. Over one year, the study measures changes in the thickness of the gum and bone around the implant to see which approach maintains better support. The goal is to find a more predictable way to preserve the natural look and structure of the smile after tooth loss.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Two dental implant placement techniques: Immediate Dentoalveolar Restoration (IDR) and the Ice Cream Cone technique
- What this could lead to
- If one technique proves better, it could guide dentists toward a more reliable method for placing implants right after tooth extraction, preserving bone and gum shape.
- What could go wrong
- This is a small, early-stage trial with only 24 participants, so results may not apply to everyone. The techniques are surgical, so risks include infection, implant failure, or damage to nearby teeth.
