An institutional protocol including socket alveoplasty and primary closure following dental extractions for patients with an elevated risk of developing medication-related osteonecrosis of the jaw.

Background The purpose of this study was to evaluate the outcomes of alveoplasty and primary closure following dental extractions in patients with an elevated medication-related osteonecrosis of the jaw (MRONJ) risk.Study design A retrospective review of 46 patients with an elevated MRONJ risk was conducted. This included a total of 124 teeth extracted, due to unrestorable caries (n = 46; 37%) and peri-apical pathology (n = 44; 35%).Results Our results showed 0% (n = 0) of patients in our cohort developed MRONJ post-operatively. Most patients were being treated with intravenous zoledronic acid for breast cancer (n = 23; 50%), with an average of 15 doses (range 1-72).Conclusions This study supports the use of alveoplasty and primary closure for patients with an elevated MRONJ risk. The authors highlight the importance of pre-operative cone beam computed tomography imaging, optimisation of immune status, post-operative prophylactic antibiotics, and the delay of bone modifying agents recommencement as influential factors in mitigating risk and favouring successful outcomes.
