A blunt force trauma injury to an instrumented human cadavermaxillae was simulated with a regulation (142 g) baseball travelingat 14 m/s. Measurements of strain were obtained with three-axisstrain gauge rosettes located at the medial palate and both caninefossae. A three dimensional finite element (FE) model of a dentatehuman maxilla was constructed from computed tomography scans of theskull of an adolescent. This three dimensional mathematical modelof the maxilla was deemed geometrically accurate through dedicatedconvergence testing and exhibited a monotonic change and subsequentconvergence of induced displacement when the total degrees offreedom approximated 74 000. The simulated load case included atransient dynamic impact to the medial maxilla with boundaryconditions imposed at skeletal buttresses of the model. The modelitself was calibrated through direct comparison with thedisplacements and principal strains gathered from experimental andepidemiological data. The comparison of experimental and calculatedprincipal strains as a result of the simulated impacts revealed a1.7 - 11.4% difference,
