PurposeThe purpose of this report is to present a reliable surgical and prosthodontic protocol for the treatment of the atrophic maxilla by placing four zygomatic implants.Materials and MethodsThe surgical and prosthodontic procedures are described for the retreatment of a 63-year-old woman who had previously undergone an iliac crest bone graft transplant, which had resorbed.ResultsIt is possible to place double zygomatic implants bilaterally, in addition to conventional implants in the anterior maxilla. Bone grafting procedures can be avoided, resulting in a fixed implant-supported maxillary prosthesis.ConclusionA logical treatment solution is four zygomatic implants for the atrophic maxilla, especially because the previous iliac crest bone graft had resorbed.
