Mandibular Symphyseal Distraction Osteogenesis (DOMS) is a common clinical procedure aimed to modify the mandibular geometry for correcting dental overcrowding problems on the inferior arch. DOMS includes two steps: The mandible is osteotomized and hence instrumented with a distraction orthodontic device which serves to expand the dental arch. This allows to correctly re-positioning teeth which were initially in contact. This work studies the structural response of the mandible subjected to DOMS. Different loading conditions and different orthodontic appliances are considered. In order to compare different distraction protocols, structural response is evaluated for different apertures given to the distractor. Structural analysis has been conducted on a 3D finite element model reconstructed from CT scan data recorded for a human mandible. The computational model includes geometric non-linearities and is corroborated by experimental data reported in literature.
