Successful Management of Peri-Implant Infection from the Endodontic Lesion of Adjacent Natural Tooth

Figure 3

Case 2: (a) Preliminary Cone-beam CT before implant placement. (b) A coronal image of site #11 indicated the absence of labial bone and poor socket healing. (c) Fistulas were observed in the labial mucosa around implant #11(red arrow). (d, e) Follow-up visit after implant placement for 5 months, radiography appeared to indicate a mesial spread of apical periodontitis in tooth #12 to the coronal peri-implant defect (red arrow). (f) Apical radiograph revealed a diagnostic Gutta-percha cone tracing from mucosal fistulas to tooth #12 (red arrow). (g) Periapical radiographs at 1-month follow-up after filling the root canal with Vitapex. (h) Cone-beam CT indicated that RCT of tooth #12 was suitable, and the peri-implant bone defect was healed after half a year. (i) Intraoral photographs half a year after root canal filling. (j) The intraoral photograph of the implant-supported restoration 7 months after RCT showed healthy peri-implant mucosa. (k) Apical radiograph showed no defects of peri-implant supporting bone. Root canal therapy, RCT.
