The findings of the present case indicate that insertion of dental implants is a risk factor for osteonecrosis of the jaw in patients exposed to bevacizumab. Therefore, prospective randomized studies should be encouraged to determine a safer bevacizumab regimen that considers both oral surgeries and the risk of dental implants for the management of osteonecrosis in clinical settings.
MRONJ is a side effect of drugs with a predilection for the mandible [24], which can be attributed to the relatively low vascularization of the mandible as compared to the maxilla [13]. Dental infections, surgical interventions, corticosteroid treatment, and chemotherapy have been described as risk factors for osteonecrosis [25]. In this case, the patient presented with stage 2 osteonecrosis with ...
Long-term administration of antiangiogenic agents does not directly indicate a high risk of MRONJ [16], though some authors have established 7-, 14-, and 28-day intervals of bevacizumab suspension for oral surgery [17,18,19]. In this case, the antiangiogenic medication was suspended for 28 days before implant placement; however, this was not enough to prevent MRONJ. The surfaces of Straumann® S...
A meta-analysis showed that the placement of dental implants in patients exposed to bisphosphonates did not reduce the success rate of the dental implant [11], although these patients may experience complications. Based on this analysis, a risk assessment should be performed on a case-by-case basis, since MRONJ is rare but one among serious complication of bisphosphonate therapy [11]. However, a c...
Five weeks postoperatively, pain, drainage of purulent secretion, and bone exposure around the implants were observed (Fig. 4), although none of the implants showed mobility. Ten ozone therapy sessions associated with levofloxacin were performed. After 4 weeks of therapy with ozone oil (Philozon®, Balneário Camboriú, SC, Brazil), no pain or drainage of purulent secretion were present. Bone s...
A 54-year-old Caucasian woman complained of an unpleasant taste and pain in the mouth. Her medical history included breast cancer with metastasis, which was diagnosed in 2007. The patient had no comorbidities and no history of smoking. A radical mastectomy with axillary dissection was performed. The patient had no previous history of radiotherapy of the head and neck or use of bisphosphonates. The...
The treatment of malignancies often involves the use of targeted therapies to control the growth and survival of malignant cells by interfering with specific molecular agents involved in carcinogenesis [1]. Bevacizumab is a recombinant humanized monoclonal antibody designed to selectively bind and inhibit the biological activity of all human vascular endothelial growth factor (VEGF-A) isoforms. It...
