本研究的目的是调查改良后的销钉系统在双颌截骨术中垂直控制上颌骨重新定位的准确性。将 239 名连续进行双颌骨截骨术的患者的术前头颅照片叠加在术后胶片上。对上切牙的计划和观察的垂直和水平运动进行统计分析。垂直移动的平均偏差为 -0.07 毫米（95% 置信区间 (CI) -0.17 至 0.04 毫米），水平移动的平均偏差为 0.12 分钟（95% CI -0.06 至 0.30 分钟），与零没有显着差异。上颌骨侵入和挤压之间的两个方差的比较也没有显着差异（p = 0.51）。这些结果表明，用于垂直控制的改良销钉系统与咬合间夹板相结合，可以在正颌手术中提供上颌前牙的精确垂直定位。 (C) 2009 年英国口腔颌面外科医师协会。由爱思唯尔有限公司出版。保留所有权利。
The aim of the study was to investigate the accuracy of a modified pin system for the vertical control of maxillary repositioning in bimaxillary osteotomies. The preoperative cephalograms of 239 consecutive patients who were to have bimaxillary osteotomies were superimposed on the postoperative films. Planned and observed vertical and horizontal movements of the upper incisor were analysed statistically. The mean deviations of -0.07 mm (95% confidence intervals (CIs) -0.17 to 0.04 mm) for the vertical movement and 0.12 min (95% CI -0.06 to 0.30 min) for the horizontal movement did not differ significantly from zero. Comparison of the two variances between intrusion and extrusion of the maxilla did not differ significantly either (p = 0.51). These results suggest that the modified pin system for vertical control combined with interocclusal splints provides accurate Vertical positioning of the anterior maxilla in orthognathic surgery.
