ABSTRACT
LOCATION OF FRACTURE Mandibular fractures are usually described by location, which affects the appropriate treatment. n Dentoalveolar: A fracture without disruption of the underlying osseous structures of the
mandible and only involving the tooth-bearing area n Condyle: Any fracture that affects the condylar process of mandible; further classified as
intracapsular, extracapsular, or neck n Coronoid: Any fracture that affects the coronoid process n Ramus: Region superior to the gonial angle up to the sigmoid notch n Angle: Region of the gonial angle, extending to the region of the third molar n Body: Any fracture that extends from the alveolar process through the inferior border and
occurs in the region between the mental foramen and the distal aspect of the second molar n Parasymphysis: Any fracture that extends from the alveolar process to the inferior border that
occurs between the mental foramen and the distal aspect of the lateral incisor n Symphysis: Any fracture that runs from the alveolar process to the inferior border of the
mandible and occurs in the region of the incisors in a vertical or near-vertical direction1
