[Epidermoid cysts and implants. Anatomo-pathologic findings]

A case is reported that is exceptional in more than one respect. The mandibular region was the site of development of three cysts: a radiculo-dental cyst, a coronodental cyst in appearance but which could have been an epidermoid cyst and a typical epidermoid cyst. Lingual nerve lesions are a rare, major complication of implantations. Dismounting of a stable implant is a very rare occurrence. Histopathology showed a bone integration process in contact with the major part of implant, an interposed fibrous band existing in certain sectors only.
