AIM: The aim of the study was to compare the body and angle of the @entity742 mandible in terms of bone density and biomechanical competence under bending load conditions. MATERIAL AND METHODS: Nineteen @entity742 mandibles were used in this study. The mandibles were separated at the symphysis into two halves. Three regions of interest on the body and angle of the hemi-mandibles were selected for measurements of bone mineral density (g cm(-2) ) by dual energy X-ray absorbtiometry. Biomechanical properties of the left mandibular body and right mandibular angle were measured by three-point bending test using a material testing machine. The load and deformation were recorded, and the load-deformation curves were obtained. The values of failure load (FL), yield load (YL), yield deformation (YD), @entity85 ( @entity85 ), stiffness, energy to yield point (EY) and energy to failure point (EF) were calculated with the analysis of load-deformation curves. Groups were compared using independent samples Student's t-test. RESULTS: The mandibular angle exhibited the lower bone density (-64%) and biomechanical properties (FL; -45%, YL; -40%, @entity85 ; -7% stiffness, -40% EY; -48% and EF; -34%) than the mandibular body under bending loads, and there was no significant difference in values of YD between the two regions. CONCLUSION: Our results show that the mandibular angle is weaker than the mandibular body under bending loads.
