Spider Zygoma: a new implant rehabilitation technique for atrophic maxilla.

OAtrophic maxilla is a challenge in dental implant surgery, and new strategies are needed. We present a new minimally-invasive approach, called "Spider Zygoma", consisting of implant-supported prosthesis with the addition of customized maxillofacial plates and screws on surface of zygomatic bone. A 3D-model of the edentulous upper jaw was used as preoperative model. Two customized bone plates were created and used as guide for placement of implants and zygomatic screws. Although this is only a pilot study, this new surgical technique seems to be safe and accurate, confirmed by the maintenance of good aesthetic and functional results after 5-year follow-up.
