Abstract: A gunshot injury is one of the main trauma injuries that affect the head and neck region. Severe esthetic, functional, and psychologic deficiencies are consequences of gunshot injuries. The use of implants anchored in the zygomatic bone has been advocated as an approach to the prosthetic rehabilitation of a severely deficient maxilla. This approach provides the patient with an immediate, high-quality, esthetic, and functional complete fixed prosthesis and eliminates the need for bone grafting. In this case report, a patient with a severely deficient maxilla caused by a gunshot injury was rehabilitated by placement of  four zygomatic and two pterygomaxillary implants, which were immediately loaded with a complete fixed all-acrylic resin interim prosthesis. The definitive CM Prosthesis (CM Prosthetics) was constructed using computer-aided design/computer-assisted manufacture (CAD/CAM) technology.

This report describes a clinical approach to using the zygomatic and pterygomaxillary bones to provide additional anchorage for longer implants to support an immediately functional maxillary screw-retained provisional fixed prosthesis. The purpose is to report the problems of patients who have experienced the most severe form of maxillary alveolar resorption and to demonstrate a specific protocol which provides immediately loaded implants without bone grafting.
