Nonlinear Biomechanical Characteristics of the Schneiderian Membrane: Experimental Study and Numerical Modeling

Figure 3

(a) Bone strip with membrane and the self-made clamp apparatus. The loading machine (BOSE) moves the indenter through the opening in the clamping plate, applying load to the center of the intermediate bone. (b) FE model of a specimen subjected to load using nonlinear mechanical properties determined experimentally. (c) The sinus membrane subjected to elastic deformation. (e) The mucosa detached from the sinus bone wall. ((d), (f)) Enlarged view of the area outlined in red.
