Prosthetic rehabilitation in maxillectomy patients aims to separate the oral and nasal cavities to provide adequate articulation, restore the contour of the midface, and provide acceptable aesthetic results. This clinical case report describes prosthetic rehabilitation via placement of dental implants in the zygomatic bone in a patient who underwent partial maxillectomy because of osteosarcoma. The success of obturator placement after maxillectomy requires retention by the surrounding dental tissue or dental implants. When zygomatic implants cannot be used, dental implants placed in the zygomatic bone and attachments fastened to these implants can easily provide the retention and stability required by the obturator.
