This study evaluated the transverse strength (rigidity) of three groups of sagittal split osteotomies performed in vitro in fresh sheep mandibles. Fixation was accomplished utilizing two different position screw techniques and a monocortical plate technique. Osteotomies fixed with three 2.0-mm screws in an inverted-L pattern and those fixed with one monocortical miniplate were significantly more rigid than those fixed with two 2.7-mm screws placed in a linear pattern. No significant difference in rigidity was noted between the inverted-L group and the miniplate group.
本研究评估了在新鲜绵羊下颌骨上进行的三组矢状劈开截骨术的横向强度（刚度）。固定采用两种不同的定位螺钉技术和一种单皮质钢板技术完成。采用倒L形三枚2.0毫米螺钉固定的截骨术和采用一枚单皮质微型钢板固定的截骨术比采用线性排列的两枚2.7毫米螺钉固定的截骨术刚度明显更高。倒L形组和微型钢板组之间在刚度上未观察到显著差异。
