Bone grafting at implant removal to help success of putting a new implant in the same spot
Official title: Effect of Bone Augmentation Simultaneous to Implant Removal on the Prognosis of Reimplantation at the Same Site
Run by The Dental Hospital of Zhejiang University School of Medicine · NCT07078890 · Data updated 2026-11-12
This study tests whether doing bone grafting at the same time as removing a failed dental implant helps people who plan to get a new implant in the same location.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with a failed implant that needs removal who plan to reimplant at the same site and have periodontal health or stabilized periodontitis after treatment are ideal candidates.
✕Probably not a fit
People with uncontrolled metabolic disease, on medications that affect bone metabolism, with an implant already detached at consultation, or unwilling to reimplant or follow up are unlikely to benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The trial compares outcomes after immediate bone augmentation at the time of implant removal with outcomes after allowing the site to heal naturally before reimplantation. Researchers will measure radiographic bone levels and clinical indicators of healing and implant success, and will also review past cases to identify factors that affect bone healing and reimplantation outcomes. Participants are adults with implant failure who plan to receive a new implant at the same site and have stable periodontal health. Follow-up visits and imaging at the participating hospitals will track short- and mid-term prognosis after reimplantation.
Why it matters
Potential benefit: If successful, simultaneous bone augmentation could improve bone healing and increase the likelihood of a successful reimplantation, reducing the need for additional surgeries.
How similar studies have gone: Similar approaches have some supportive but limited evidence and results have been mixed, so this approach is not yet firmly established.
