SIMPLIFIED PROTOCOL FOR INTRA OR EXTRA SINUS ZYGOMATIC IMPLANTOLOGY: NEW CLASSIFICATION METHOD

Abstract

Branemark developed a protocol for edentulous patients who had no residual bone by using bone of the same embryonic origin, i.e. zygomatic bone, in combination with the installation of conventional implants. Over time, there has been a significant increase in demand for zygomatic implants and we have witnessed the evolution of the technique, such as Professor Reginaldo Miglioranza's outsourced methodology. In this study, 279 zygomatic implants were placed in 126 patients, observing the relevance of an already established technique (with 25 years) and by far the most desirable, with the author proposing a new classification for zygomatic implant installation, following the original externalised technique in a simple and intuitive way; the simplified protocol for Externalised Zygomatic Implantation (ZES) includes only two possibilities ZETA (Zigomatic Externalised Fully Supported) and ZEPA (Zigomatic Externalised Partially Supported), supported by the lateral sinus wall.
