摘要: 目的: 利用2种三维打印技术制作钛合金颅颌面接骨板,并将其表面及内部形态与标准型的接骨板进行比较。方法: 获取标准型接骨板数据,分别运用选择性激光融化技术(selective laser melting, SLM)和电子束熔融技术(electron beam melting, EBM)进行三维打印制作。将未抛光的SLM钛板、EBM钛板和已抛光的SLM钛板、EBM钛板,连同标准型钛板分别进行表面粗糙度检测和内部缺陷测试。获取结果后,进行形态学描述,并采用SPSS 13.0软件包进行统计学分析。结果: 三维打印的颅颌面接骨板具有较大的粗糙度。通过对表面打磨和抛光,能够显著降低其表面粗糙度。经过表面处理后,其粗糙度满足国家行业标准,并且与标准型接骨板的表面粗糙度无显著差异。内部缺陷检测结果显示,3种接骨板内部均未出现明显的不连续缺陷,符合国家行业标准和使用要求。结论: 三维打印钛合金颅颌面接骨板具有较好的表面及内部形态,其表面粗糙度和内部缺陷基本满足国家行业标准。

Abstract: PURPOSE: To study the surface and internal morphology of titanium alloy craniomaxillofacial bone plate manufactured by two kinds of three-dimensional printing techniques and compare with conventional titanium plate. METHODS: Stereolithography data (STL) of conventional titanium plates were obtained and used to fabricate bone plate by selective laser melting (SLM) and electron beam melting (EBM). Part of the titanium plate was selected for surface polishing treatment. The roughness and internal defects of the unpolished SLM titanium plate, EBM titanium plate and the polished SLM titanium plate, EBM titanium plate together with conventional titanium plate were examined. Relevant images and data were obtained for image description and further statistical analysis with SPSS13.0 software. RESULTS: The three-dimensional printing titanium plate had a large roughness. However, the surface roughness can be significantly reduced by surface polishing. After surface polishing process, the roughness declined significantly and met the standards of the national industry standards. After surface polishing process, there was no significant difference of the surface roughness between the three-dimensional printing titanium plate and the conventional bone plate. As regard to internal defect, there was no obvious defect in the three types of bone plates, which met the requirements of the national industry standards and clinical application. CONCLUSIONS: The three-dimensional printing titanium alloy craniomaxillofacial bone plate has nice surface and internal morphology, and its surface roughness and internal defects basically meet the national industry standards.
