Biomechanical study of static pressure on facial bone fractures. Part I. Strain distribution under static loads.:Part I Strain Distribution under static Loads

To achieve a complete under-standing of the biomechanical aspects involved when maxillofacial bones are stricken by external forces, it is necessary to study them as one body. Experiments carried out following this concept are reported here. Different weights were applied to the mandible at the center of the mental region and the distribution of principal strains of bone were analyzed.It was found that force is transmitted through the mandibular bone along the bone radial structure. On the maxillofacial bone, the zygomatic arch received most of the stresses and suffered frequent damage.
