Özet
Prosthetic rehabilitation of the upper jaw in patients with severe bone and soft tissue defects is still a significant problem due to insufficient retention and stability. Zygomatic implants have been proposed for the rehabilitation of patients with insufficient bone avoiding costly and time consuming grafting procedures. A 65-year-old male patient was referred to department of prosthodontics with functional and esthetic issues. His clinical and radiographic examination revealed a lower full arch implant-supported fixed prosthesis and a severely atrophic maxilla. Multiple surgical steps would be required in the reconstruction of the maxilla with conventional implants, however, there was a significant barrier to patient's acceptance of grafting procedures. 4 zygomatic implants (Zygoma, Novodent SA, Yverdon-les-Bains, Switzerland) were placed to support a bar retained overdenture. Six months after the implant placement, final fixed restorations were delivered. The contemporary literature has described the use of zygomatic implants to avoid extensive bone grafting procedures for patients who have less residual alveolar bone in the premaxilla and the bicuspid region. In such cases, the zygomatic implants have been an alternative to extensive maxillary grafting procedures. Multiple authors have reported the success rate for zygomatic implants to range from 94% to 100%. This is helpful for surgeons, dentists and prosthodontists to make optimal designs of prosthesis in clinical in order to enhance the patients quality of life as much as possible. Use of zygomatic implants provide a satisfactory non-grafting option for rehabilitation of patients with maxillary atrophy or defect.
