description | BACKGROUND/AIM: Different types of plates are used in clinical practice for the management of subcondylar fractures. This study aimed to compare the performance of poly-L-lactic acid (PLLA) and titanium trapezoidal plates in the fixation of subcondylar mandibular fractures using finite element analysis. METHODS: Titanium and PLLA trapezoidal plates and screws were placed on the virtual model obtained from computed tomography images of a patient with a subcondylar fracture to perform finite element analysis. The analysis included maximum tension distribution, maximum principal strain, displacement, and deformation of the bone, plates, and screws. RESULTS: The maximum tension distribution and maximum principal stress were found to be significantly higher on the titanium plate than on the PLLA plate and screws. Almost no difference was found between the trapezoidal and PLLA plates regarding the displacement of the fracture fragments at the fracture line. No difference was recorded regarding the displacement of the PLLA and titanium screws. The values of maximal principal strain between the PLLA and titanium materials showed no significant difference. CONCLUSIONS: The trapezoidal PLLA plates can be an alternative to trapezoidal titanium plates due to their functional stability and rigidity. |
