A distraction assembly system (DAS), consisting of a distractor of fully individualized fixation plate unit and factory-engineered distraction unit, was recently developed to enhance the accuracy, stability, and workability of distraction osteogenesis (DO). We here wanted to evaluate the accuracy of DAS for mandibular DO, focusing on the consequences of the distractor design and manufacturing method. The bar-type distractor unit showed smaller discrepancies than did the cylinder-type one, both units showing far fewer discrepancies than those of a conventional distractor. And there were no significant differences in morphological accuracy between the plates produced by milling and 3D printing. These accuracies feature the promising application in clinical setting, and further work is anticipated to refine DAS for successful computer-aided DO.
一种分散装配系统（DAS），由完全个体化固定板单元和工厂制造的分散单元组成，最近被开发出来以提高分散成骨术（DO）的准确性、稳定性和操作性。我们在此旨在评估 DAS 用于下颌 DO 的准确性，重点关注分散器设计和制造方法的结果。杆式分散器单元的差异比筒式小，两者的差异都比传统分散器小得多。铣削和 3D 打印制造的固定板之间在形态学准确性上没有显著差异。这些精度为临床应用提供了有前景的应用，预计将进一步改进 DAS 以实现成功的计算机辅助 DO。
