Multiple screw placement patterns and techniques have been described for fixation of the sagittal split ramus osteotomy. This study evaluated transverse strength (rigidity) of six groups of simulated sagittal osteotomies fixed with different screw patterns and placement techniques. Osteotomies fixed with screws placed in an inverted L pattern were significantly more rigid than those fixed with screws placed in a linear pattern or K-wires placed in a triangular pattern (P less than .05). No significant difference in rigidity was noted between compression and bicortical screws placed in identical patterns.
已描述了多种用于矢状劈开下颌支截骨术固定的螺钉置入模式和技术。本研究评估了六组采用不同螺钉模式和置入技术固定的模拟矢状截骨术的横向强度（刚度）。采用倒L形置入螺钉固定的截骨术比采用直线形置入螺钉或三角形置入克氏针固定的截骨术刚度显著更高（P小于0.05）。相同模式下置入的加压螺钉和双皮质螺钉在刚度上无显著差异。
