Abstract

The purpose of this study was to analyze stress distributions in zygoma implants (ZIs), supporting bones, superstructures, and implant screws placed in the defective and non-defective areas of the maxillary bone of a patient with a maxillary defect. Three-dimensional (3D) finite element models (FEMs) were constructed based on computed tomography (CT) data. ZIs of the same size were placed in the defective and non-defective areas. After applying the force, the stress on the implants, surrounding bones, and implant screws was evaluated. Stress distribution and displacement were greater in the implant and surrounding bone on the defective side. While the stress was higher in the cortical bone on the defective side, the stress was more on the cancellous bone on the defective side. More stress was observed on the implant screw on the defective side. A ZI placed in the defective area in patients with maxillary defects should be supported by another ZI on the non-defective side.
