Update in dental implant periapical surgery. Med. oral patol. oral cir.bucal (Internet) [online]. 2006, vol.11, n.5, pp.429-432. ISSN 1698-6946.

Implant periapical lesions are infectious-inflammatory alterations surrounding an implant apex, and can be caused by a number of situations - including contamination at instrumentation, overheating of bone, and the prior existence of bone pathology. The diagnosis is based on the clinical manifestations and radiological findings, where a radiotransparency can be seen at periapical level. The lesions are classified according to their evolutive stage as either acute (non-suppurated and suppurated) or chronic (or periapical abscess). The management of implant periapical lesions comprises periapical surgery with curettage and irrigation in the acute phase, or implant extraction when the bone surface is affected and/or primary fixation is lost (chronic phase).

Palavras-chave : Implant periapical lesion; implant periapical pathology; apical periimplantitis.
