Addi-tionally, most of mandibular fractures occur in the mandibular angle and condylar process. On the other hand, the incidence of fracture of coronoid process is extremely low. We experienced a case of mandibular fractures involving mandibular body, condylar process as well as the coronoid process in a man aged 3₉–years–old who had received strong direct external force to the mandible. Mandibular fractures usually occur in the condylar process and mandibular angle because direct external force is more likely to transmit to these re-gions. Based on the classification of mandibular fractures, the incidence of mandibularfractures involving coronoid process increases with an increased number of fractures lines that means complicated fracture. At the viewpoint of anatomical portion, direct external force dose not transmit to coronoid process; however, it is possible that direct external force may transmit coronoid process in the case of complicated fracture. In this case report, we considered the potential mechanism of fracture of coronoid process by using a three–dimensional finite element model of a human mandible stress distribution analysis., application/pdf}, pages = {43--49}, title = {筋突起骨折を含む下顎骨骨折の 1 例}, volume = {45}, year = {2019} }
