Paper Abstract

Electronic Speckle Pattern Interferometry (ESPI) has been used in experiments to measure displacement on the surface of bones undergoing external forces. However in order to asses directly the derivative of the displacements a related technique, Shearography, is used. This technique has been applied in biomechanical experiments although limited to small pieces of bone to determine their elastic properties. In this work we propose the use of Shearing Speckle Interferometry to evaluate the mechanical behaviour of the human mandible under compressive stress, simulating masticatory forces or impacts, in order to analyze the strain distribution on mandibular bone.
