Abstract: Objective: To report the clinical application of zygomatic implants in patients with severe bone atrophy and defect in maxillary posterior regions. Methods: 7 zygomatic implants and 13 conventional dental implants were implanted in 4 patients. 3D CT reconstruction of jaws was performed in all patients before operation. A 1:1 maxillary models were made using 3D printing technique to design the locations and directions of implantation of zygomatic implants, according to the Branemark zygomatic implant method. Results: 7 zygomatic implants and 13 conventional dental implants were implanted in ideal axial and position. Temporary fixed denture rehabilitation was performed from 1 to 7 days after implantation, and permanent denture rehabilitation was performed after 3 months. Followed up for 6 months to 2 years, dentures function normally. Conclusion: The zygomatic implantation is a feasible method for the reconstruction of masticatory function in patients with severe bone absorption and maxillary defect.
