Abstract:

BACKGROUND: With the advancement of bio-printing technology and chemical synthesis technology, the incorporation of these technologies into tissue engineering scaffolds for promoting bone regeneration has become a hot topic in current research.

OBJECTIVE: To introduce bioactive bone tissue engineering scaffolds, and to discuss and summarize the application of different scaffold materials in promoting bone regeneration and treating bone defects.
METHODS: The first author searched PubMed, Web of Science, SpringerLink, and Medline databases in July to September 2018 for relevant articles published from 2003 to 2018 using the keywords of “bone tissue engineer,3D-printed, scaffold, composite scaffold”. Initially, 237 articles were retrieved, and only 70 articles were eligible for result analysis.

RESULTS AND CONCLUSION: Bioactive scaffolds mainly include metal composite scaffolds, bioceramic composite scaffolds and polymer composite scaffolds, which have been used in bone tissue engineering. Several examples of successful bone and cartilage construction with clinical transformation have been developed, in which bioceramic and polymer composites may be the most successful due to their similar tissue composition and good biocompatibility with natural bone. And if combined with existing bioactive materials, growth factors, functionalization techniques and biomimetic scaffold designs, the potential for creating complex bone tissue engineering scaffolds for patient-specific applications in the future is enormous. This also provides hope for the treatment of a variety of challenging diseases, including bone tumor, osteoporosis and severe bone defects.
