The trancings of condylar movement of Angle class two division one subdivision malocclusion with mandibular retrusion during mandibular movement are smooth and continual curve. There are no differences with condylar movement distances, condylar inclination and the hinge axis rotation between right and left condyle. There are no variance to movement form of the hinge axis comparing with normal occlusion. But the overlapping gender of condylar movement trace decrease than normal occlusion.
