We report a case of medication-related osteonecrosis of the jaw (MRONJ) in a 47-year-old woman with rheumatoid arthritis, who was treated with implant prosthodontics after extirpation of necrotic bone. The patient had been taking alendronate sodium hydrate, which is a bisphosphonate, for one year and two months. She lost the lower right canine and first premolar, and MRONJ occurred in the right side of the mandible. We extirpated necrotic bone with MRONJ and extracted several teeth in the region. After these treatments, normal healing of the mucosa was seen. Two implants were placed in the residual ridge of the mandible. These implants were successfully integrated and functioned well. These results suggested that implant treatment could be a treatment choice after extirpation of necrotic bone with MRONJ, but careful consideration is necessary.
