Investigation of stress occurring on fixation systems and mandibular bone in fixation of mandible symphysis fractures with different plate systems

Abstract

Aims: The aim of this study is to investigate the effectiveness of CFR-PEEK plates by comparing titanium plates with CFR-PEEK plates in the fixation of mandibular symphysis fractures.
Methods: In the study, a model that imitates the mandible was obtained with the finite element analysis method. A fracture line was created in the symphysis on the model, and a double mini-plate was applied to this line with the Champy method. Comparisons were made by assigning CFR-PEEK and titanium material properties to the plates.
Results: Von Mises stresses on screws and plates were found to be lower than those on titanium plates when CFR-PEEK plates were applied. When the stresses in the screws were examined, it was observed that the highest stresses occurred in the screws adjacent to the fracture line.
Conclusion: CFR-PEEK materials provide a more stable fixation by reducing the stresses in the fixation systems and may be a good alternative to titanium materials with their advantageous properties.
