Abstract

The literature contains considerable data on the traumatic effects of head-neck acceleration due to rear-end collisions. The temporomandibular (jaw) joint is also subject to indirect loading, due to its inertial behavior. Only a small body of work, Schneider et al (1989), describes motion of the mandible in these circumstances. In this study we investigate the nature of forces reacted within the temporomandibular joint (TMJ). A model has been built which is a precise representation of the TMJ embodied in a physically exact model cranium. The whole is mounted on an RID-III cervical spine. Sled tests were performed. Results high angular velocities and accelerations of the mandible for low velocity rear-end impacts.
