Quad Zygomatic Implants for Rehabilitation of Atrophic Maxilla: A Case Report and Review
Main Article Content
Abstract
Patients with moderate to severe atrophic maxilla challenge the surgeon to discover alternative ways to use existing bone or resort to augmenting the patient with autogenous or alloplastic bone materials. Many procedures have been suggested for these atrophied maxillae before implant placement, which include Le Fort I maxillary downfracture, onlay bone grafts and maxillary sinus graft procedures. A zygomatic implant can be an effective device for rehabilitation of the severely resorbed maxilla. If zygomatic implants are used, onlay bone grafting or sinus augmentation will not be necessary. The purpose of this paper is to review the indications of zygomatic implants placement techniques, stabilization, and prosthodontic procedures.
