A human clinical and histologic report of an osseointegrated titanium alloy root form implant.

Endosteal implants fail for a variety of reasons. These include failure to osseointegrate, long-term loss of osseointegration, and invasion of a vital structure or anatomic placement that prohibits its use. This case report describes the removal of an implant because of patient discomfort secondary to invasion of the mandibular canal. These histologic findings offered a unique opportunity to examine an osseointegrated human dental implant section.
