Immediate loading with zygomatic implants for edentulous maxilla with giant maxillary sinus: a case report

doi:10.12337/zgkqzzxzz.2025.06.005

Abstract

Abstract: In this paper, a patient with severe alveolar bone atrophy in the maxillary posterior region, a giant pneumatized maxillary sinus, and insufficient restoration space underwent zygomatic implantation with immediate loading. Following extraction of the remaining maxillary teeth and occlusal space elevation by 6 mm using a temporary denture, bilateral maxillary zygomatic and inclined implants were placed. Immediate loading was completed 3 days after implant placement, and final restoration was achieved after 6 months. Based on a comprehensive analysis of the patient’s preoperative clinical data, the authors eliminated several alternative surgical approaches and ultimately selected the bilateral zygomatic implantation protocol, which successfully restored the patient's maxillary edentulism. By analyzing this case, the authors synthesized treatment principles and clinical experiences for the diagnosis and management of similar cases, providing valuable insights for addressing comparable implant scenarios.
