Fig. 1. Pre-operative: Subgingival caries at 35 and a vertical root fracture at 36 were observed.
Fig. 2. Implantation: An 8 mm fixture was used due to anatomical constraints, but initial fixation was not obtained for 35.
Fig. 3. During bone regeneration: Cytrans® Granules (M size) mixed with blood were filled and laser was used for blood clot formation.
Fig. 4. After suturing: Although the epithelial defect was an open wound, it was sutured just enough to bring the flap closer in order to prevent narrowing of the oral vestibule.
Fig. 5. Before secondary surgery 4 months later: No evidence of delayed healing, recession or infection of the mucous membrane.
Fig. 6. During secondary surgery: A sufficient amount of bone regenerated around the fixture, and favorable secondary fixation was obtained.
Fig. 7. Approximately one year after bone regeneration treatment: No inflammation was observed in the surrounding tissue.
Fig. 8. Approximately one year after bone regeneration treatment: There is no evidence of resorption of the surrounding bone, even in X-ray images.
