Diabetes drug may boost dental implant success, small study finds
NCT ID NCT07469254
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding 1% metformin gel to a bone graft improves bone healing and implant stability in people getting immediate dental implants. Twenty adults aged 18 to 40 with a non-restorable tooth in the front or premolar area took part. The researchers measured implant stability and gum health over 12 months to see if the gel made a difference.
