Prosthetic Rehabilitation of Atrophic Maxilla by Extrasinus Zygomatic Implants: An Illustrative Case Report

Prosthetic rehabilitation of severely atrophied jaws remains a major challenge in implant dentistry. Zygomatic implants offer a viable alternative where conventional implants are not feasible. We present the first documented case of zygomatic implant rehabilitation using the extrasinus technique in Nepal. A 49-year-old male with severe maxillary atrophy was treated with two anterior conventional implants and two zygomatic implants, while the mandible received four implants. The patient was rehabilitated with a Malo bridge and hybrid prosthesis. The patient was followed up for 6 years; the implant showed excellent stability with no clinical or radiographic signs of complications, and the patient reported a high level of satisfaction with the functional and aesthetic outcomes.
