Abstract
A bilateral sagittal split osteotomy was performed on seven fresh cada ver mandibles. Three different systems of fixation were mechanically t ested on 14 sites. Tensile diagrams were obtained in which the (offset -) yield point was measured. This resulted in mean yield stresses of 1 99 N for bicortical self-tapping screws (n = 6), 49 N for miniplates w ith monocortical screws (n = 5), and 113 N for bicortical biodegradabl e rods (n = 3).
