Various screw placement patterns have been described for fixation of the sagittal split ramus osteotomy. This study is a comparative evaluation of 3 different screw placement patterns on the rigidity of the sagittal split ramus osteotomy. Twenty cadaver mandibles were used to compare the load strength of triangular pattern, oblique linear pattern versus linear pattern. Internal fixation with screws placed in a triangular pattern were significantly more rigid than those fixed with screws placed in the other patterns. Also, internal fixation with an oblique linear pattern was more rigid than that with a linear pattern.
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。本研究是对3种不同螺钉置入模式在矢状劈开下颌支截骨术刚性方面的比较评估。使用20具尸体下颌骨来比较三角形模式、斜线形模式与线形模式的负载强度。以三角形模式置入螺钉进行内固定明显比以其他模式置入螺钉固定的更具刚性。此外，斜线形模式的内固定比线形模式的更具刚性。
