Figure 2. Representative photographs of a single-unit implant-supported maxillary right lateral incisor restoration exhibiting peri-implant mucositis. (A) Presentation of the restoration and its surrounding peri-implant mucosa during clinical exploration. After 4 years of follow-up, no suppuration was observed, and probing depths of 3 to 5 mm persisted on all surfaces. However, overt bleeding at 2 sites and mild tissue edema were apparent. (B) A periapical radiograph shows a conical-type implant with an internal abutment connection and no evidence of alveolar bone loss.
