Deep peri-implantitis: two cases treated with implant apicoectomy with follow-up of at least 7 years

摘要

Aim: Deep periimplantitis is a lesion located in the periapical region of an osseointegtated implant. The aim of this study was to present 2 cases of this feature treated with apicoectomy. Materials and methods: Two cases of deep periimplantitis located in the maxillary premolar region are presented in this report. Both the lesions were situated in the apical segment of otherwise osseointegrated and long (15 mm) implants. They were treated with surgical debridement, apicoectomy, bone substitute and antibiotics. Results: Bone overheating, proximity to periapical lesions or previous inflammation seem to be the three possible causes of the lesions in the cases presented. The follow-up period of 7 and 10 years indicates that implant apicoectomy is a safe and reliable treatment choice. Conclusions: The treatment of choice for deep periimplantitis is implant apicoectomy, unless the implant is mobile, where implant removal is preferable.
