Abstract:
BACKGROUND: In recent years, more and more scaffold materials have been used to repair soft tissue defects, and the clinical repair effect of soft tissue defects is strongly associated with the source and performance of materials. OBJECTIVE: To summarize the research progress of preparation and application of different biological scaffolds in the field of oral and maxillofacial soft tissue defect repair. METHODS: PubMed and Medline were searched for articles published from 1966 to 2019 with the English key words of “materials, scaffold, biological scaffold, soft tissue, coloboma, tissue engineering, review”. Chinese journal full-text database and Chinese science citation database were retrieved for articles published from 2003 to 2019 with key words of “material, scaffold, biological scaffold, soft tissue, defect, tissue engineering, review”. RESULTS AND CONCLUSION: Natural bio-scaffold materials are directly derived from organisms with pretty biocompatibility. Natural bio-scaffold materials can release cytoactive factors, promote cell adhesion, proliferation and differentiation, and can be combined with synthetic polymer materials with controllable properties to form composite scaffolds, which is an ideal scaffold material for repairing soft tissue defects of oral and maxillofacial regions. Nanomaterials have higher biological activity than other scaffold materials and can promote the adhesion and proliferation of seed cells, providing ideal three-dimensional space for cell growth, but their applications are currently mainly reflected in bone tissue repair, and the applications in soft tissue repair are very few. At present, there are many researches on natural biological scaffold materials in oral and maxillofacial soft tissue repair, mainly including small intestinal submucosa, acellular dermal matrix and acellular vascular scaffolds. The combination of natural biological scaffold materials and synthetic polymer materials will be a major research trend in materials for repairing oral and maxillofacial soft tissue defects.
