Full arch rehabilitation of post-mucormycosis edentulous maxilla using quad zygomatic implants: a clinical case report

Abstract

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.
