OBJECTIVE: Bisphosphonate related osteonecrosis of the jaw (BRONJ) is progressive bone destruction in the maxillofacial region of patients under current or previous treatment with Bisphosphonates. The present case series study aimed to evaluate if ozone/oxygen therapy and debridement with piezoelectric surgery may improve the treatment of BRONJ.

PATIENTS AND METHODS: The treatment modality of the patients included ozone/oxygen mixture from medical oxygen. The protocol for ozone/oxygen mixture therapy appointments was set as twice a week for 10 weeks, for a total of 20 applications for each patient. The evaluation of the lesions was based on the clinical and radiologic parameters. The primary outcome was the necrotic lesion reduction during ozone/oxygen therapy sessions and up to the end of follow up periods. The healing of the lesion was taken as a positive result. The level of significance was taken as p <0.05.

RESULTS: A total of 14 patients affected by osteonecrosis were included. The mean follow-up of the patients was 14.3 months. The overall success rate after treatment was 64.2%.

CONCLUSIONS: According to the results, ozone/oxygen therapy and debridement with Piezoelectric surgery for BRONJ treatment is a safe procedure with successful outcomes.
