Implant pathology associated with loss of periapical seal of adjacent tooth: clinical report.

A mandibular cuspid adjacent to two implants placed in the incisor region redeveloped periapical pathosis as a result of the inadvertent removal of the gutta-percha seal during post preparation. The root end inflammatory process communicated with the surface of an adjacent implant, resulting in endodontic-implant pathosis and subsequent removal of the implant. The osteotomy site healed uneventfully and almost complete osseous repair was observed after five months.
