The oral rehabilitation of MRONJ patients represents a challenging situation. Conventional dental implant insertion is not indicated because of the risk of creating a new necrotic area. This case study describes the oral rehabilitation of a 78-year-old female patient, who developed an osteonecrotic lesion in the fourth year of bisphosphonate treatment. The patient underwent a series of surgeries, including resection of the necrotic tissue on the right maxillary region and removal of conventional implants. The patient had a large maxillary defect, and no other treatment modalities such as conventional prosthetic appliances and traditional dental implant insertions were applicable. The patient had a very poor quality of life and as a rehabilitation option, two zygomatic implant insertions were planned and performed as an anchorage for maxillary fixed prosthesis. Radiographic and clinical examination after three years of follow-up indicated that healing was achieved, and healthy tissues formed around zygomatic implants. The patient did not suffer from any additional necrotic tissues or other complications in the oral cavity. According to the results of this case report, zygomatic implantation after resective surgery might be considered as a promising alternative for MRONJ patients with large defects when other treatment alternatives fail or are not applicable.

Abstract

The oral rehabilitation of MRONJ patients represents a challenging situation. Conventional dental implant insertion is not indicated because of the risk of creating a new necrotic area. This case study describes the oral rehabilitation of a 78-year-old female patient, who developed an osteonecrotic lesion in the fourth year of bisphosphonate treatment. The patient underwent a series of surgeries, including resection of the necrotic tissue on the right maxillary region and removal of conventional implants. The patient had a large maxillary defect, and no other treatment modalities such as conventional prosthetic appliances and traditional dental implant insertions were applicable. The patient had a very poor quality of life and as a rehabilitation option, two zygomatic implant insertions were planned and performed as an anchorage for maxillary fixed prosthesis. Radiographic and clinical examination after three years of follow-up indicated that healing was achieved, and healthy tissues formed around zygomatic implants. The patient did not suffer from any additional necrotic tissues or other complications in the oral cavity. According to the results of this case report, zygomatic implantation after resective surgery might be considered as a promising alternative for MRONJ patients with large defects when other treatment alternatives fail or are not applicable.
