Treatment and Resolution of an Implant Periapical Lesion (IPL) with Guided Bone Regeneration.

Abstract

Background: Implant periapical lesion (IPL) is a rare condition that can affect dental implants. Several different approaches have been proposed for the treatment of this condition. Awareness and literature discussing this condition and possible treatment options have grown significantly in the last 25 years. Case Presentation. The present case report describes the treatment of an implant periapical lesion with a combined approach consisting of surgical lesion removal, mechanical instrumentation with titanium brush, detoxification with tetracycline, and guided bone regeneration (GBR) with demineralized allograft bone and cross-linked collagen membrane. The patient was followed up for 6 months postoperatively, showing complete resolution of the buccal fistula. No signs or symptoms of discomfort or pathology were reported.

Conclusions: The case report presented a combined approach that can be successful in the surgical treatment of an IPL in which the implant stability is maintained.
