The posterior maxillary ridge affected severely by resorption remains a challenge for the prosthodontist to rehabilitate. Extensive grafting procedure and the restriction of a transitional denture during the healing phase in most situations are deniable to the patient. The zygoma implant provides posterior maxillary support when the existing osseous structures do not allow the placement of a conventional implant fixture. A 57-year-old female patient came with a chief complaint of completely missing upper and lower front teeth and wanted a fixed replacement for the same. The conventional full arch fixed implant-supported prosthesis was not possible because of the severe posterior maxillary atrophy, and so it was decided to place two zygoma implants bilaterally splinted with four implants placed conventionally in the anterior ridge. The mandibular arch was treated with four implants based on the All-On-4® concept. The success of an implant-supported prosthesis is based on how effectively the forces of mastication are distributed through the implants and tissue surface. The scope of a zygoma implant in rehabilitating severely resorbed maxilla and the various prosthodontic principles pertaining to a full arch implant-supported prosthesis are discussed in detail.
