Objective: Rehabilitation of severely atrophic maxilla is a significant clinical challenge in implantsupported
prosthetic treatments. This study aims to compare iliac crest-derived autogenous bone
graft and zygomatic implant approaches in terms of indications, advantages, and disadvantages
through two different cases.
Case: Case 1: A 36-year-old male patient presented with complete edentulism and advanced
maxillary atrophy. Clinical and radiological evaluation revealed significant vertical and horizontal
bone loss. Under general anesthesia, an autogenous cortico-cancellous block graft was harvested
from the anterior iliac crest and fixed to the maxilla with titanium screws. After six months of healing,
dental implants were placed.
Case 2: A 69-year-old female patient presented with advanced maxillary atrophy and a request for
fixed prostheses. A cone-beam CT scan revealed insufficient residual bone height. Bilateral zygomatic
implants were placed, achieving high primary stability.
Conclusion: The choice of treatment for the rehabilitation of the atrophic maxilla should be determined
according to the patient’s systemic condition, age, degree of atrophy, expectations regarding
treatment duration, and the surgeon’s experience. While iliac crest grafting is a reliable method for
restoring bone volume, zygomatic implants provide a graftless and faster alternative in cases of
advanced atrophy.
