Investigation of stress occurring on fixation systems and mandibular bone in fixation of mandible symphysis fractures with different plate systems. Dicle Dental Journal, 25(1), 1-5.2822-6755https://dergipark.org.tr/en/pub/dicledentj/issue/83876/1435737https://hdl.handle.net/11468/29430Aims: The aim of this study is to investigate the effectiveness of carbon fiber-reinforced polyetheretherketone (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.eninfo:eu-repo/semantics/openAccessMandible fracturesCFR-PEEK plateTitanium plateFinite element analysisInvestigation of stress occurring on fixation systems and mandibular bone in fixation of mandible symphysis fractures with different plate systemsInvestigation of stress occurring on fixation systems and mandibular bone in fixation of mandible symphysis fractures with different plate systemsArticle25115
