Abstract

The Implant periapical lesion (IPL=Implant Periapical Lesion) is an infectious-inflammatory alterations surrounding an implant apex. The diagnosis is based on the clinical manifestations as pain, swelling, presence of fistula and radiological findings, where a radiolucent lesion can be seen in the periapical area. It is apparent that IPL has a multifactorial background, mainly caused by the presence of a pre-existing microbial pathology or surgical trauma during implant surgery. To date, there are no clinical protocols for managing IPL. This case report presents a case history related to IPL, which was caused by a pre-existing lesion. For the treatment of the infected form of IPL, a sequential surgical therapy can be utilized, if there is no loss of the implant stability. This includes surgical removal of the implant apical region, through debridement of the infected lesion, systemic antibiotics, and or guided bone regeneration. The intervention was aimed to stop the progression of osteolysis perimplant increasing the survival implant.
