Significant maxillary atrophy poses a considerable obstacle for oral restoration with standard dental implants because of insufficient bone supply. Zygomatic implants provide alternative treatments without a graft by being secured into the sturdy zygomatic bone, enabling support for prosthetic restoration. Thus, zygomatic implants were proposed in this case report as a substitute for costly and lengthy grafting techniques for rehabilitating patients with insufficient bone.We describe a 62-year-old male who was diagnosed with maxillary atrophy and who underwent a rehabilitation protocol involving zygomatic implants. Two bilateral zygomatic implants were planned as free-hand surgical procedures because of the lack of a supporting structure to stabilize the surgical template. Prostheses were then placed after 48 hours, and a radiographic follow-up occurred at 24 months. Regular check-ups and proper oral hygiene were maintained. The clinical data and radiographs for the control treatment were obtained throughout the two years following treatment. Patients achieved functional and aesthetic rehabilitation with no major complications reported during the follow-up period. High levels of patient satisfaction and prosthetic function were observed.This case report highlights the effective rehabilitation of a severely atrophic maxilla using quad zygomatic implants, achieving immediate function and aesthetics with no major complications over two years. Compared with traditional bone grafting, the graftless approach is less invasive, leading to faster recovery and greater patient satisfaction.
