Fig. (3) Analysis of Graft surface alignment. Left column: Contour maps of von Mises stress distribution for various alignment conditions showing significant increase with proud placement of the graft. Right column: Leaving the graft proud significantly increased peak contact stresses, von Mises stresses, and compressive strains in the graft. Recessing the graft tended to reduce of peak contact and von Mises stresses in the graft (‘+’ indicates a graft raised above the recipient surface, ‘-‘ indicates a graft recessed below the recipient surface).
