Mandibular fractures with sagittal splitting and splaying of both the near and far cortices pose a challenge in their fixation as screws may push the far cortex during screw tightening, resulting in more widening. Screw lagging inside the lower mandibular plate technique may help approximation of the near and far cortices during screw tightening, and this was applied for 4 cases with mandibular fractures. The splaying improved using this technique. Using the screw lagging inside the plate technique may be a safe technique used in mandibular fractures that have cortical splaying.
下颌骨骨折伴有近远侧皮质骨的矢状劈开和张开，在固定方面具有挑战性，因为在拧紧螺钉时，螺钉可能会推动远侧皮质骨，导致更严重的增宽。下颌骨下部钢板内螺钉滞后技术可能有助于在拧紧螺钉时使近远侧皮质骨靠拢，该技术应用于4例下颌骨骨折患者。采用该技术后张开情况有所改善。在下颌骨皮质骨张开的骨折中，使用钢板内螺钉滞后技术可能是一种安全的技术。
