Fig. 2. Boundary and loading condition of the FEA models (Zircon and Titan models). Both groups of models are fixed in all directions. (A) A force of 320 N was applied in a direction parallel to the axis of the placed fixture, and the fixture and abutment were considered to be fully engaged. (B) Oblique and vertical loadings were obtained with the application of 175 N in two directions onto the eight occlusal areas.
