The zygomatic implants, originally designed by Branemark in 1989, are implants with a 45 degree inclined head, 4'5 millimetre diameter at their widest part and measuring between 30 and 50 millimetres in length. They are inserted from the palatine side of the alveolar process, following the zygomatic-alveolar edge and anchor in the body of the zygomatic bone. In the case of maxillectomized patients, they are inserted directly in the body of the malar bone. These implants offer an additional alternative to the surgeon when planning an implant supported rehabilitation treatment; specially in those patients with an atrophic maxilla in which osseous grafts cannot be realized or these grafts have failed. The objective of this article is to propose the surgical,protocol of placement of traszygomatic implants and to check the current literature on the clinical evolution of these implants.
