Management of a failed mandibular staple implant: a clinical report.

A 48-year-old woman sought treatment because her staple implant-retained overdenture was no longer retentive, and the denture was worn over the abutments. After unsuccessfully attempting to move the retentive nuts along the transosseous posts of the staple implant, the posts were cut off at the level of the bone. Two endosseous implants were placed around the staple implant, and a new implant-retained overdenture was fabricated and inserted using ball attachments for retention. This article describes the treatment for this patient, who has been wearing the new dentures successfully for the past 4 years.
