摘要
本研究系钛板颌骨重建及内固定系统的综合研究。实验研究包括固定器的化学成分检验，机械性能测试，生物力学效应和组织反应性评价。临床资料为３１９例颌骨固定的回顾性分析总结。结果显示各类固定器系统主要性能指标基本达到设计要求，但小型接骨板挠曲强度偏低，固定结构刚度不足，钛制板钉表面耐磨性差，需进一步改进工艺，提高性能。文中概括了固定器使用效能分类及适应证，提出了颌间固定的条件和时间，对比分析了使用各类固定器并发症的主要原因。该固定系统在颌骨外科应用中具有可靠性和临床价值。
Titanium plate screw systems for maxillofacial reconstruction and internal fixation were studied including examination of chemical components, measurement of mechanical natures, biomechanical and biological evaluation, in combination with retrospective analysis of 319 cases fixed by means of plate screw appliances. The results demonstrated that all experimental data have satisfied basically the design and clinical requirements, with the exception of a weaker curve resistance and fixative stability of miniplate as well as lower surface wear resistance of pure titanium. So, further improvement is necessary. Additionally, the function classification and indication of plate screw systems are discussed. The duration and condition of intermaxillary fixation is suggested. The complications and their causes are analysed through comparison among different fixation systems.
