Summary

This trial tests whether regular or narrow dental implants work better for supporting a full lower denture in people who have lost all their teeth. Lower dentures often slip because of bone loss and tongue movement, which affects comfort and confidence. Researchers will place two implants in the lower jaw and use 3D imaging to measure bone height and density around each implant over time. The goal is to see which implant size offers better support and bone preservation.

What this could mean

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

Active substance
Two types of dental implants: regular and narrow diameter, placed in the lower jaw to support a complete denture.
What this could lead to
If one implant type proves better, it could guide dentists toward a more stable and comfortable option for lower dentures in people with bone loss.
What could go wrong
This is a small early-stage trial with only 12 participants, so results may not apply to everyone. Implant surgery carries risks like infection or implant failure.
