Full Oral Rehabilitation - Quad Zygoma with Extra-Sinusal Implants Placement Technique with Pterygoid Implants and Four Traditional Implants in The Lower Jaw with Immediate Loading: A Case Report

Abstract

Today it is more and more frequent to find ourselves faced with severe atrophy of the upper jaw due to bone defects of various kinds, physiological, pathological and iatrogenic. With the help of extraoral bone anchorage it is possible to solve those cases that cannot be solved with traditional implantology. Zygomatic implantology can manage these types of atrophies by rehabilitating the patient with a fixed prosthesis and, where possible, with immediate loading. These solutions represent an alternative to bone grafts (graftless solutions) which provide for much longer healing times and with patient discomfort given the contraindication to immediate loading. The same goes for the lower arch which involves rehabilitation with a low number of implants, two of which tilted to avoid noble anatomical structures such as mental nerves in order to reach the posterior areas (premolar area) minimizing the prosthetic cantilever. I present a clinical case where through the use of zygomatic and pterygoid implants for the upper jaw and four lower implants it was possible to restore function and aesthetics by installing two screw-retained temporary fixed prostheses.
