Successful periodontal regeneration requires the hierarchical reorganization of multiple tissues including periodontal ligament, cementum, alveolar bone, and gingiva. The limitation of conventional regenerative therapies has been attracting research interest in tissue engineering-based periodontal therapies where progenitor cells, scaffolds, and bioactive molecules are delivered. Scaffolds offer not only structural support but also provide geometrical clue to guide cell fate. Additionally, functionalization improves bioactive properties to the scaffold. Various scaffold designs have been proposed for periodontal regeneration. These include the fabrication of biomimetic periodontal extracellular matrix, multiphasic scaffolds with tissue-specific layers, and personalized 3D printed scaffolds. This review summarizes the basic concept as well as the recent advancement of scaffold designing and fabrication for periodontal regeneration and provides an insight of future clinical translation.
成功的牙周组织再生需要包括牙周膜、牙骨质、牙槽骨和牙龈在内的多种组织的层次重组。传统再生疗法的局限性引起了人们对基于组织工程的牙周治疗的研究兴趣,其中可以输送祖细胞、支架和生物活性分子。支架不仅提供结构支撑,还提供几何线索来引导细胞命运。此外,功能化可提高支架的生物活性特性。已经提出了各种用于牙周再生的支架设计。这些设计包括仿生牙周细胞外基质的制造、具有组织特异性层的多相支架和个性化 3D 打印支架。本文综述了支架设计和制备用于牙周再生的基本概念和最新进展,并展望了未来的临床转化。
