This cadaveric study demonstrates a new zygomatic implant method that shows feasibility for maxillary defects, indicating potential for improved patient outcomes.
Key Points
To evaluate a novel reverse insertion technique for zygomatic implants and its feasibility in cadaveric models.
Simulated a Brown Class II maxillectomy in a fresh-frozen cadaver.
Virtually planned and placed four custom reverse zygomatic implants using CAD/CAM surgical guides.
Compared superior and inferior orbital approaches for placement accuracy.
Used postoperative CT to assess deviations and a 3D-printed verification bar for prosthetic alignment.
All implants were successfully inserted with primary stability.
The superior approach exhibited lower deviations at the zygomatic bone (1.25 mm vs. 2.32 mm) and intraorally (4.7 mm vs. 7.3 mm).
Angular deviation was better with the superior approach (1.85° vs. 5.63°).
Intraoral emergence remained clinically acceptable, allowing partial seating of the verification bar.
