Abstract

Peri-implant inflammation may originate at the lateral surface of the implant, a condition known as lateral peri-implantitis; however, the condition remains underrecognized among clinicians. A 42-year-old non-smoking female patient underwent implant placement and lateral ridge augmentation in the anterior maxillary area (#12). The healing process was uneventful, and the implant functioned successfully without any adverse events. However, after 7 years, the patient reported tenderness at the implant site. The cone-beam computed tomography (CBCT) scan revealed a labial depression in the augmented tissue and loss of radiopacity. During surgical re-entry, a large bone defect encompassing two-thirds of the implant was identified. The exposed implant surface was decontaminated using titanium curettes, a titanium brush, and a tetracycline-hydrochloride solution (for 5 minutes). Bone grafting was performed on the defective area, followed by connective tissue grafting. The implant site healed uneventfully, and successful integration of the reaugmented bone was confirmed by CBCT scan 1 year after re-entry. No specific complications were noted. Although lateral peri-implantitis is rare, it can compromise the long-term stability of implants, underscoring the importance of understanding this condition.
