Özet

The aim of finite element analysis (FEA) study was to compare two zygomatic implant (ZI) techniques in combination with conventional implants. A FEA model was constituted based on computed tomography data of a patient. ZIs were virtually placed into models with sinus slot or extra sinus techniques combined with two or four conventional implants. Occlusal forces were applied from the buccal direction. The von Mises stress values in implants and the principal stress values in alveolar bone were analyzed. Four conventional implants and the sinus slot technique showed lower stress values. Two ZIs with the sinus slot technique and four conventional implants may be biomechanically safer for atrophic maxilla rehabilitation.
