摘要
背景:电子束熔融快速成型技术(EBM RP)是一种新型金属粉末快速成型技术,它具有精准、复杂成型的特点,已在航空航天、汽车和医疗植入器材等领域显示独特的应用优势。目的:探索电子束熔融快速成型技术用于骨科植入物时表现出的产品性能、个性化定制能力,尤其是诱导骨长入能力。方法:计算机检索Pubmed数据库、中国期刊全文数据库、知网数据库,手工检索《东方早报》《世界科学》《中国骨科杂志》,以及相关的中英文会议论文集。所有检索时间均截止至2013年9月。纳入标准:①应用电子束熔融快速成型技术的文章。②外科植入物相关文章。最后选择50篇文献进行分析。结果与结论:EBM态Ti6Al4V骨科植入物具有良好的产品综合性能;电子束熔融快速成型技术具有优良的个性化定制能力,尤其是生成的3D连通的孔隙结构,可提供诱导骨长入的结构性条件,在骨科植入物方面享有独特的优势。
BACKGROUND：Electron beam melting rapid prototyping technology, has the characteristic of shaping precisely and complexly, is a new type of rapid prototyping technology using metal powder. Now, it has shown unique advantages in the fields of aerospace, automotive and medical implant equipments. OBJECTIVE： To explore the properties of the product, the customization ability of orthopedic implants through electron beam melting rapid prototyping, especial y the ability of inducing bone ingrowth. METHODS：We retrieved PubMed Database, China Journal Ful-text Database, and China National Knowledge Infrastructure, as wel as Dongfang Daily, World Science, and Chinese Journal of Orthopaedics by hand, and assembly documents in Chinese and English. Retrieval time was up to September 2013. Inclusion criteria： ① articles concerning electron beam melting rapid prototyping technology; ② articles addressing surgical implants. A total of 50 articles were included. RESULTS AND CONCLUSION：Electron beam melting state Ti6Al4V orthopedic implant has a good comprehensive performance, since the three-dimensional porous structure via electron beam melting rapid prototyping, which has a characteristic of customization, can induce bone ingrowth.
