Riassunto
L’ostenocrosi delle ossa mascellari da farmaci (MRONJ) rappresenta un effetto avverso conseguente al trattamento con farmaci antiriassorbitivi e farmaci antiangiogenetici. In letteratura i dati riguardanti MRONJ e posizionamento implantare sono controversi. Esistono due scenari di rischio: il primo riguarda il rischio di MRONJ associato al posizionamento implantare ed il secondo riguarda il rischio di MRONJ associato a perimplantite. Lo scopo di questo studio è quello di presentare le caratteristiche cliniche, radiografiche ed il trattamento chirurgico di una coorte di pazienti affetti da osteonecrosi dei mascellari associata a perimplantite. Sono stati inclusi retrospettivamente trentadue pazienti (27 femmine; età media: 65,74 anni) che presentavano 59 impianti associati a MRONJ, trattati presso il reparto di Odontostomatologia e Chirurgia Orale dell’Ospedale Universitario di Pisa da gennaio 2012 a dicembre 2020. Diciotto pazienti erano in trattamento con bifosfonati per via endovenosa per il trattamento di patologie oncologiche. Quattordici pazienti assumevano bifosfonati per via orale per il trattamento dell’osteoporosi. Lo stadio più frequente di MRONJ è risultato essere lo stadio III, seguito dallo stadio II. In tutti i casi le lesioni erano sintomatiche ed erano prevalentemente localizzate a livello mandibolare. Al follow-up di 12 mesi, si evidenzia un tasso di guarigione completa nell’84,4% dei casi, con il 100% di successo per le osteonecrosi localizzate a livello del mascellare. Stratificando il tasso di successo in base allo stadio della lesione si evidenzia il 100% di guarigione per le lesioni in stadio II e dell’83% per le lesioni in stadio III.
Medication-related ostenocrosis of the jaw bones (MRONJ) represents an adverse effect following treatment with antiresorptive drugs and antiangiogenic drugs. In literature, data regarding MRONJ and implant placement are controversial. There are two risk scenarios: the first concerns the risk of MRONJ associated with implant placement and the second concerns the risk of MRONJ associated with peri-implantitis. The aim of this study is to present the clinical, radiographic and surgical treatment features of a cohort of patients affected by osteonecrosis of the jaw associated with peri-implantitis. Thirty-two patients (27 females; mean age: 65.74 years) were retrospectively enrolled in this study. They were treated at the Department of Odontostomatology and Oral Surgery of the University Hospital of Pisa from January 2012 to December 2020. In total, 105 implants were evaluated, with MRONJ being present around 59. Eighteen patients were being treated with intravenous bisphosphonates for the treatment of oncological diseases. Fourteen patients took bisphosphonates orally for the treatment of osteoporosis. The most frequent stage of MRONJ was found to be stage III, followed by stage II. In all cases, the lesions were symptomatic and were predominantly located in the mandibular area. At the 12-month follow-up, there was a complete cure rate in 84.4% of cases, with 100% success for osteonecrosis localized in the jaw. Supplemental stratification indicated 100% disease resolution for all stage II lesions, 83.3% disease resolution for stage III.
