Severely atrophied jaws pose a challenge to implant-supported rehabilitations. Maxillary reconstruction with bone graft to allow rehabilitation with implants is a treatment with good predictability and high success rate. However, a morbidity is the disease of the donor regions and the greater amount of bone hinders the acceptance of the patients; including, be contraindicated depending on the systemic condition. This article is a review of the literature, such as the indications, complications, predictability of rehabilitations with zygomatic implants, as well as a case report. The zygomatic implants appeared as an alternative for the rehabilitation of maxilectomized patients, due to the excision of tumors. However, the technique was extrapolated to the cases of severe bone atrophy, as approached in the case in question, and bone losses due to infections or trauma, reducing the time and morbidity of the treatment, when compared to the bone reconstruction. Rehabilitation with zygomatic implants may present complications, such as poor placement of implants, compromising rehabilitation; however, despite the limitations of the technique, the literature shows that zygomatic implants, when well indicated, represent a good alternative for the rehabilitation of severely atrophied maxillae.
