Abstract

Through the case report of a patient who suffered trauma to the face, presenting a complete fracture line in the left mandibular parasymphysis region, as well as an incomplete bilateral condylar fracture line (“green branch” pattern), the study intends to revisit the literature on the ideal lines of rigid fixation for osteosynthesis of the mandible, the influence of tension and compression zones in the choice of plates and screws and, finally, the reason for the essential use of two parallel fixation forces in the anterior region of the mandible. Method: Analysis and monitoring of emergency care procedures in the emergency department of the Ruth Cardoso municipal hospital/Balneário Camboriú-SC, clinical and tomographic examinations, photographic records before and after the surgical procedure (up to the third month after trauma), outpatient follow-up after hospital discharge and literature review on the proposed topic. Conclusions: By restoring function and aesthetics through osteosynthesis appropriate to the biomechanical standards of the mandibular bone, proposed since Maxime Champy and still endorsed by the AO Foundation (Association for the Study of Internal Fixation), among the treatment possibilities, it was concluded that the good quality of the material needs to be linked to constant scientific knowledge (biomechanical and surgical) to optimize clinical results.
