Zygomatic Implants Literature Review and a Clinical Case Involving Bone Grafting and the Importance of the Use of Multiunit ELEMENT<sup>®</sup> Transepithelial Abutments

Zygomatic implants, originally designed by Dr. Branemark in 1989, are implants which could have 45 to 55 -degree heads of angulation, 4.2 or 4.5 millimeters in diameter at their widest point and measuring between 30 and even 50 or 60 millimeters in length. They are inserted from the palatal aspect of the alveolar process, following the zygomatic-alveolar crest until they are anchored in the body of the malar bone. In maxillomandibular patients, they enter directly into the body of the malar bone. These implants offer the surgeon an alternative when planning implant-supported prosthetic and rehabilitation treatment, especially in patients with severely atrophied upper jaws, where bone grafting is impossible or has previously failed. And also, a reliable and predictable option for immediate loading prosthesis, which is relevant for the comfort, confidence and aesthetics of the patient. The objective of this article is to present the surgical protocol for placing zygomatic implants and a robust review of the current literature on the clinical evolution of these implants and their different techniques. And no less important, to show the advantages, purpose and benefits of using curved and more anatomical transepithelial abutments with a multiunit platform when we need to place an immediate load and definitive full arch prosthesis.
