Early implant infection and failure can be addressed by either implant maintenance or immediate replacement and bone regeneration at the defect site.


In this study, six patients with chronic sinusitis at the implant site were treated with implant removal and curettage to remove the infected and inflamed soft tissue. A new implant was immediately screwed into the same socket, and a Guided Bone Regeneration (GBR) procedure was performed to regenerate the lost bone at the site. After the patients underwent the second surgery, the sinusitis disappeared, and new bone formed around the implant, achieving good implant stability.


The implant was loaded, and no complaints were reported during the follow-up period. Chronic implant infection treated with implant removal and immediate replacement plus GBR resulted in stable new implants with new bone formation.

Keywords: Peri-implantitis, Failing implant, Osseointegration, Sinusitis, Bone loss, Chronic implant infection.
