Abstract :Purpose The purpose of this study to compare the biomechanical stability of the fixation system made of CFR-PEEK and titanium alloy with the three-dimensional finite element analysis method insert ignore into journalissuearticles values(FEA); in the internal fixation of an unfavorable insert ignore into journalissuearticles values(inferior to superior, anteriorly oblique); mandibular angle fracture in which muscle tractions increase the amount of displacement. Materials and Methods A virtual unfavorable fracture line was formed on the mandible models. Fracture lines were virtually fixed with 4-hole, 1.0 mm profile thickness mini-plates with bar and 5 mm long titanium screws. Mini plates were designed from two different materials insert ignore into journalissuearticles values(titanium alloy and CFR-PEEK);. These plates were placed in three different positions insert ignore into journalissuearticles values(Position A: single miniplate from the lower side, Position B: double miniplate, Position C: single miniplate from the upper side);. To simulate the bite forces, 200 N force insert ignore into journalissuearticles values(anterior incisor and posterior molar); was applied separately in the vertical direction. Results All-titanium miniplate systems were able to withstand 200N molar and anterior loads, but the double miniplate system showed the lowest stress value. CFR-PEEK plates could not show strength in single miniplate systems under 200N molar and anterior forces, they showed strength only in double miniplate systems. CFR-PEEK double plate system reduces the stress on the bone by approximately 40% in anterior and molar loadings compared to titanium miniplates placed in the same positions. Conclusion As a conclusion, to the titanium plates used in current practice, CFR-PEEK materials can also be used in the field of maxillofacial traumatology in the future.
