Purpose: The 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 Methods: The surgical and prosthodontic procedures are described for the retreatment of a 63-year-old female patient who had previously undergone an iliac crest bone graft transplant, which had resorbed.

Results: It 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.

Conclusion: A logical treatment solution is four zygomatic implants for the atrophic maxilla, especially because the previous iliac crest bone graft had resorbed.

KEY WORDS: atrophic maxilla, implant-supported prosthesis, endosseous dental implants, sinus-lift procedures
