Abstract
Zygomatic implants are a mainstay of reconstructive implantology, and are typically employed in cases of severe maxillary atrophy, or following midface resection secondary to malignancy. There are two major problems that challenge successful and predictable zygomatic implant placement: firstly, the amount of available bone for zygomatic implants is often minimal, thus precise placement is paramount, particularly if multiple fixtures are to be used. Secondly, given the length of zygomatic implants can be four times that of conventional dental implants, even a small inaccuracy in implant angulation, once extrapolated along the length of the fixture, can result significant apical deviation and subsequent iatrogenic perforation of the orbit or the infratemporal fossa.
