Measurement guidelines for ramus height, condylar process inclination, and radiodensity. Ramus height was defined as the distance from the point of the mandibular angle (gonion, Go) to the uppermost point of the condylar process of the mandible (condylion, Co). Condylar process inclination was defined as the angle of the imaginary line connecting the gonions of both sides and extension of the central axis of the condylar process. A bone area of 5 mm around the fracture site was set as the regions of interest for radio-density measurement.
