摘要:


文题释义:

3D打印技术:使用计算机辅助设计软件将数字模型转换为逐层打印的指令,然后将材料(如塑料、金属或生物材料)逐层添加到打印平台上,直到形成所需的物体。3D打印技术可以用于制造各种物体,从小型零件到大型建筑模型和人体组织工程。
牙周组织工程:牙周组织包括牙龈、牙周膜、牙骨质和牙骨膜等,这些组织在牙周疾病(如牙周炎和牙周病)发生时会受到不同程度的损伤。牙周组织工程是一种利用生物学、材料学和工程学的原理和方法,通过种植细胞、生物材料和生长因子等来重建和恢复受损牙周组织的过程。


背景:3D打印是牙科领域的一项新兴技术。它使用一种分层制造技术来创建可用于牙周组织工程应用的支架。通过3D打印的组织支架能够创建具有可控的特性,如内部结构、孔隙度和互联性,这使得它成为一种非常理想的牙周组织工程策略。

目的:综述3D打印支架在牙周再生过程中的应用进展。
方法:以“3D printing,periodontal tissue engineering,additive manufacturing,regenerative medicine,bioengineering,scaffold,bioprinting,periodontitis;3D打印,增材制造,牙周组织工程,支架,生物墨水,生物打印,组织工程学”为检索词,运用计算机检索PubMed、CNKI数据库中2000-2023年发表的相关文献。

结果与结论:随着过去几十年3D打印技术的突飞猛进,它在组织工程和生物医学领域中都取得了巨大的突破和进展。3D打印技术能够提供高度个性化的治疗方案,提高治疗支架的适配性与治疗效果,在牙周组织工程中具有广阔的应用前景。在牙周组织工程领域中,3D打印的应用可以更好地模拟生物组织复杂的结构,并且能够制造出具有合适力学、流变学等特性的生物支架材料。3D打印技术通过组织工程支架的逐层构建不仅可以为牙周疾病治疗创建精确而复杂的支架模型,并且能在支架中创建复杂的微结构和通道,以促进细胞生长和组织再生。

Abstract: BACKGROUND: Three-dimensional (3D) printing is an emerging technology in the field of dentistry. It utilizes a layer-by-layer manufacturing technique to create scaffolds suitable for periodontal tissue engineering applications. Tissue scaffolds produced through 3D printing can possess controlled characteristics, including internal structure, porosity, and interconnectivity, making it an ideal strategy for periodontal tissue engineering.
OBJECTIVE: To review the applications of 3D printed scaffolds in periodontal regeneration. 
METHODS: English search terms were “3D printing, periodontal tissue engineering, additive manufacturing, regenerative medicine, bioengineering, scaffold, bioprinting, periodontitis”. Chinese search terms were “3D printing, additive manufacturing, periodontal tissue engineering, scaffolds, bio-inks, bioprinting, tissue engineering”. Relevant literature published from 2000 to 2023 in PubMed and CNKI databases was retrieved and included in the review.
RESULTS AND CONCLUSION: Over the past few decades, 3D printing technology has made significant progress and breakthroughs in tissue engineering and biomedical fields. 3D printing technology can provide highly personalized treatment programs, improve the suitability and therapeutic effect of therapeutic stents, and has broad application prospects in periodontal tissue engineering. In periodontal tissue engineering, 3D printing applications can better mimic the complex structures of biological tissues and manufacture biocompatible scaffold materials with suitable mechanical and rheological properties. The layer-by-layer construction of tissue engineering scaffolds through 3D printing not only enables the creation of precise and intricate scaffold models for personalized treatment of periodontal disease but also facilitates the incorporation of complex microstructures and channels within the scaffolds to promote cell growth and tissue regeneration.

Key words: 3D printing, periodontal tissue engineering, additive manufacturing, regenerative medicine, bioengineering, scaffold material
