Abstract

Rehabilitating the maxilla in the patient who has had surgical resection for mucormycosis poses a distinctive set of anatomical, surgical, and prosthetic challenges. The extensive maxillary bone loss after aggressive debridement often makes traditional implant-supported prosthetic options impossible. In these circumstances, zygomatic implants have proven to be a predictable, graftless solution, especially in patients with extremely atrophic maxillae. Where the bone loss is severe, the quad zygoma procedure—two implants for each zygomatic arch—is possible to support full arch rehabilitation with a fixed prosthesis. This report presents the successful rehabilitation of oral function and appearance in a patient with post-mucormycosis edentulous maxilla, treated with four zygomatic implants and a screw-retained hybrid prosthesis. The article addresses preoperative evaluation, surgery protocol, prosthetic process flow, and clinical results, stressing the long-term effectiveness and clinical applicability of this method for medically compromised individuals.
