摘要/Abstract

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,并将其生物力学性能与锻造的成品化钛板进行比较。方法获取成品化钛板数据,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。将成品化钛板、SLM钛板和EBM钛板分别进行三点弯曲的静态力学检测和洛氏硬度检测。获取检测数据后,利用SPSS13.0软件包对数据进行统计学分析。结果所有测试均顺利完成,方差分析显示,其屈服载荷结果为SLM>EBM>成品化,最大载荷结果为SLM>EBM>成品化,差异均具有统计学意义。洛氏硬度检测结果为SLM>成品化>EBM,两两比较显示,2种方式的洛氏硬度值与成品化钛板的差异无统计学意义。结论三维打印的钛合金接骨板具有较好的生物力学性能,其力学强度和硬度基本满足国家及行业标准。

Abstract: PURPOSE: To study the mechanical properties 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). Static mechanical test and Rockwell hardness test of the conventional titanium plate, SLM titanium plate and EBM titanium plate were carried out. The SPSS13.0 software package was used to analyze the data. RESULTS: All the tests were successfully completed. Variance analysis showed that the yield load was SLM>EBM>conventional plate, and the maximum load was SLM>EBM>conventional plate, the difference was statistically significant. Rockwell hardness test results was SLM> conventional plate>EBM, multiple comparison showed that the difference of the two techniques and conventional plate was not statistically significant. CONCLUSIONS: The preliminary results show that three-dimensional printing titanium alloy plate has nice biomechanical properties, and its mechanical strength and hardness meet the national and industrial standards.
