This study aimed to analyze the biomechanical behavior of the cranial implant by varying materials (titanium, hydroxyapatite, and zinc-hydroxyapatite) and pore size (600, 900, and 1200 μm) through a finite element method since there is a lack of study on this area. The cranial implant was reconstructed from the DICOM images, and the biomechanical behavior was evaluated in terms of Von Mises stress and deformation. The maximum Von Mises stress was primarily influenced by pore size in this study. Meanwhile, the material properties had the greatest influence on the implant’s deformation. Subsequently, the safety factor was considered, and titanium implant with a pore size of 900 µm showed excellent results.
