Multiple techniques of internal screw fixation are being used in clinical oral and maxillofacial surgery. This study evaluated the uniaxial pull-out strength of five commonly used screws and Kirschner pins placed by five different techniques. The pull-out strength of the Kirschner pins was significantly less (P greater than .0001) than that of the screws. The screw techniques did not differ significantly.
临床口腔颌面外科正在使用多种内固定螺钉技术。本研究评估了五种常用螺钉和通过五种不同技术置入的克氏针的单轴拔出强度。克氏针的拔出强度明显低于螺钉（P大于0.0001）。螺钉技术之间没有显著差异。
