Cortical bone resorption secondary to endodontic-implant pathology. A case report.

A single implant was inserted to replace the mandibular right lateral incisor in a 50-year-old Caucasian woman. After one month, an endodontic lesion formed on the adjacent canine, which went on to engulf the fixture. Even though endodontic therapy was instituted expeditiously on the canine, the implant exfoliated spontaneously the following month. There was a large radiolucency afterwards, suggesting resorption of both the labial and lingual cortical plates. A follow-up radiograph four months later revealed a residual detect along with delayed wound repair.
