Prevention of mandibular fractures by using constructional design principles. I. Computer simulation of human mandibular strength after segmental resections.

A study was carried out on mechanical stress at the resection site in mandibles undergoing segmental resections. A computer simulation model was used to study particularly the effect of various radii of the posterior resection corners and the effect of elimination of muscle action. It was found that an enlarged radius of the resection corner in conjunction with coronoid process resection on the ipsilateral side offers the best condition to prevent fracture of the mandible.
