Fig. 1. Panoramic X-ray image at onset of peri-implantitis.
Fig. 2. Pre-operative intraoral photograph. The superstructure was removed, a healing abutment was placed at 25, and a cover screw was placed at 26.
Fig. 3. Intraoral findings after incision and detachment. Saucer-shaped bone resorption occurred around the implant and was surrounded by granulation tissue.
Fig. 4. Granulation tissue was removed as a single mass, and the surface of the implant is thoroughly cleaned with a titanium brush and titanium ultrasonic tip.
Fig. 5. Autologous bone collected from the maxillary tuberosity and Cytrans® Granules (S size) were mixed at a ratio of 50:50 and applied.
Fig. 6. Comparison of X-ray CT image at the onset of peri-implantitis and approximately half year after regenerative treatment (coronal image).
Fig. 7. Intraoral photograph 1 year after regenerative therapy. The superstructure has been modified for better cleanability.
Fig. 8. Dental X-ray photograph of the same. The implant is clinically and radiologically stable.
