摘要:

文题释义:
细胞支架复合体:将细胞在体外培养后接种于支架材料上,用于构建人工器官或组织已取得了卓越的进展。当前研究多为单一细胞类型或单一培养环境的单相支架,从组织内结构的角度看来,三维支架可能更好地模拟下方包括基底膜在内的复杂内部结构,但仍面临难度大、成本高、耗时长的困难。 
牙周软组织增量:是一种改善牙龈及周围黏膜的美学异常、修复体或种植体周围软组织高度与厚度不足的手术,包括冠向复位、侧向复位的根面覆盖术及游离龈移植、双层技术等结缔组织移植。

背景:牙周软组织量不足带来天然牙及修复体的红白美学问题,导致牙龈炎、种植体周围炎等疾病发生。不同细胞及材料组合的细胞支架复合体可以促进牙周软组织再生,有望取代自体移植物。
目的:综述自体或同种异体成纤维细胞、角质细胞、间充质干细胞结合支架材料应用于牙周软组织增量的研究进展及突破。
方法:在 PubMed、CNKI、万方、Sciencedirect、Medline数据库中进行相关文献检索,以“牙龈退缩,软组织增量,根面覆盖术,上皮下结缔组织移植物”及“gingival recession,soft tissue augmentation,root coverage,subepithelial connective graft”为关键词进行搜索,阅读摘要、结论进行初步筛选,排除与文章主题无关的研究及试验,最后纳入61篇文献进行结果分析。 
结果与结论:间充质干细胞在龈乳头增量方面展现出不小的潜力。单纯的成纤维细胞或角质细胞联合胶原蛋白、壳聚糖、脱细胞真皮基质等支架移植在软组织增量上未能取得预期角化龈增量,尽管两种细胞联合胶原蛋白基质表现出更为乐观的结果且当前的支架材料具有良好可塑性、生物相容性,然而成纤维细胞及角质细胞的共培养费时且成本高昂,加上支架材料的构象较为单一,如何解决这些问题仍是一段漫长的过程。

Abstract: BACKGROUND: Insufficient amount of periodontal soft tissue always brings red-and-white aesthetic problems of natural teeth and restorations, leads to gingivitis and peri-implant inflammation. Cell scaffold complexes with different cell and material combinations can promote periodontal soft tissue regeneration, which is expected to replace autogenous grafts.
OBJECTIVE: To review the research progress and breakthrough in the application of autologous or allogeneic fibroblasts, keratinocytes, and mesenchymal stem cells in periodontal soft tissue increment.
METHODS: Literature retrieval was conducted in PubMed, CNKI, Wanfang, Sciencedirect, and Medline databases. The key words were “gingival recession, soft tissue augmentation, root coverage, subepithelial connective graft” in English and Chinese. Abstracts were read; conclusions were preliminarily screened; and studies and experiments unrelated to the topic of this paper were excluded. Finally, 61 articles were included for result analysis.
RESULTS AND CONCLUSION: Mesenchymal stem cells show great potential in gingival papilla increment. Transplanting only fibroblasts or keratinocytes combined with collagen, chitosan, acellular dermal matrix and other scaffolds in soft tissue could not achieve the expected keratinized gingival increment. Although the combination of two kinds of cells and collagen matrix showed more optimistic results and the current scaffold materials had good plasticity and biocompatibility, co-culture of fibroblasts and keratinocytes is time-consuming and expensive, and the conformation of scaffold material is relatively single. How to solve these problems will be a long process.

Key words: materials, oral cavity, scaffold, gingival recession, periodontal regenerative medicine, soft tissue graft, tissue engineering, review
