Zygomatic implant on a severely resorbed maxillary arch in a HIV positive patient. Considerations in medical work up and treatment planning: A case report

Abstract

Background: The indications for using zygomatic implantsinvolve cases with severe resorption of the maxillary arch resulting in inadequate bone volume. The case report aims to review the HIV virus and current protocols, perioperative management and the surgical approach of zygomatic implant placement in combination with traditional implants in an HIV-positive patient. Case report: A 59-year-old HIV positive male patient presents with atrophic maxillary and mandibular arches. Surgical placement of two zygomatic implants, two endosseous implants in the maxillary arch, and six endosseous implants in the mandibular arch. A reduction of a large palatal tori was also performed. The patient exhibited no complications after the surgical procedure. The hybrid prostheses were inserted post surgically without any issues. Conclusion: Zygomatic implants can be an optimal treatment option for prosthetic rehabilitation in patients with atrophic maxilla for better functionality and aesthetics. This case demonstrates the perioperative work up and placement of zygomatic implants in a medically stable HIV-positive patient with no adverse effects five months post-operation. Various surgical approaches may be utilized with excellent patient acceptance and predictable outcomes.
