Medication-related osteonecrosis of the jaw (MRONJ) is a serious concern for dentists as well as maxillofacial surgeons. Therefore, the safety of dental implant placement in patient receiving antiresorptive drugs (ARDs) has been the subject of controversial debate for several years and remains a source of uncertainty for surgeons and patients. This consecutive case series assessed the clinical and radiographic outcomes of dental implants placed in patients under antiresorptive therapy. Patients who received at least one dental implant at the Department of Oral and Maxillofacial Surgery, Ludwig Maximilian University (LMU), Munich, Germany, between 2010 and 2019 with a history of current or past antiresorptive medication were included the study. The main outcomes were occurrence of MRONJ, implant success, and survival rate. A total of 16 patients were treated with 39 implants. No implant loss or MRONJ occurred in the respective patients. The reasons for antiresorptive intake were osteoporosis, malignancy, edema of bone marrow, or diffuse sclerosing osteomyelitis (DSO). MRONJ occurred neither around implants nor in other locations. Cumulative implant success was 92.6% (25 of 27). No subjective complaints or postoperative complications were documented. Mean bone loss was 0.60 ± 0.98 mm. The prevalence of peri-implantitis was 30% on patient level and 29.6% on implant level. None of the patients had failed implants. No major complications after implant placement under antiresorptives could be detected. As long as implant surgery follows a specific protocol, implant placement in patients treated with antiresorptive therapy seems to be safe and predictable.
