Dental implant study explores best way to heal edentulous jaws
NCT ID NCT06408506
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study involved 20 patients with no teeth in their lower jaw who needed six dental implants. Researchers compared implants that were immediately loaded (with a temporary tooth) to those left unloaded or healed under the gum. The goal was to gather information on implant survival, bone healing, and patient satisfaction over 24 months to improve future dental implant procedures.
