文题释义:
快速成型技术:计算机辅助设计及制造技术、逆向工程技术、分层制造技术、材料去除成形或材料增加成形技术以及它们的集成。即快速成形技术就是利用三维CAD的数据,通过快速成型机,将一层层的材料堆积成实体原型。
表面改性技术:采用化学、物理方法改变材料表面的化学成分或组织结构以提高材料性能的一类处理技术。通过材料表面改性以提高生物材料的生物相容性,以保证材料与机体相适应。生物领域主要包括表面涂层技术、表面接枝改性技术、等离子体表面改性技术、光化学固定技术表面仿生修饰技术等。
 
摘要
背景:3D打印能够根据患者不同组织器官的具体解剖数据,利用计算机设计构建个性化三维支架材料,快速精确的重建缺损组织/器官,如骨、软骨、肌肉、血管等,但在应用过程中也存在诸多未知问题。
目的:通过查阅近年有关3D打印技术在骨组织工程领域的应用,在3D打印技术原理及分类、支架材料分类及特点及组织相容性等方面作总结, 为构建组织工程骨的基础研究提供理论依据。
方法:检索PubMed数据库、中国知网数据库(CNKI) 2001年1月至2017年1月发表有关3D打印技术在骨组织工程中应用的文献。以“快速成型、3D打印、骨组织工程”为检索词,排除重复性研究,选择具有代表性的30篇文献进行讨论、综述。
结果与结论:3D打印支架材料可模仿正常组织微观结构,实现种子细胞、支架材料同步打印,实现种子细胞分化、生物材料降解同步进行并修复缺损部位组织。生物陶瓷具有良好的生物相容性及机械强度,已成为应用最广泛的骨组织工程支架材料,但组织工程骨血管生长、细胞信号传导仍亟待解决。

Abstract:

BACKGROUND: Individual three-dimensional (3D) scaffolds can be constructed by 3D printing via Computer Aided Design based on the given anatomical measurements of related tissues. A rapid and accurate reconstruction of bone, cartilage, muscle and vessel also can be achieved by 3D printing; however, many problems still remain unsolved.

OBJECTIVE: To summarize the principle and classification of 3D printing, the classification, characteristics and histocompatibility of scaffolds through reviewing the articles addressing 3D printing applied in bone tissue engineering, thereby providing theoretical foundation for the study on the construction of tissue-engineered bone.
METHODS: PubMed and CNKI databases were retrieved for the literatures regarding the application of 3D printing technology in bone tissue engineering published from January 2001 to January 2017 using the keywords of “three-dimensional printing, rapid prototyping manufacturing, bone tissue engineering” in English and Chinese, respectively. Finally, 30 articles were reviewed and discussed in accordance with the inclusion and exclusion criteria.
RESULTS AND CONCLUSION: The microstructures of normal tissues can be reconstructed and seed cells are printed on the 3D scaffolds synchronously by 3D printing technology. Moreover, the scaffold degradation and cell differentiation are synchronous, which contributes to tissue repair. Biological ceramics have been widely used in bone tissue engineering because of its good biocompatibility and mechanical properties. However, the urgent problems such as angiogenesis and cellular signal transduction still need to be addressed.
