Abstract:
BACKGROUND:Great development has been made in the research of various repair materials and tissue-engineered bone, and different materials exhibit a strong ability to repair bone defects. OBJECTIVE:To review the research status and progress of repair materials for bone defects. METHODS:PubMed, PMC, CBM, CNKI and WanFang databases were used online to retrieve the relative articles regarding repair materials for bone defects published from June 2007 to June 2017. The key words were "biomaterials, bone repair materials, bone substitute, bone tissue engineering, bone defect, bone repair" in English and Chinese, respectively. Finally, 66 eligible articles were included, while the unrelated and repeated ones were excluded. RESULTS AND CONCLUSION:The main repair materials for bone defects include autologous bone, allogeneic bone, xenogeneic bone, demineralized bone matrix, bioceramics, metal materials, polymer materials,tissue-engineered bone and relative derived composites. Different materials have shown certain advantages and disadvantages. Clinicians should make an optimal choice in view of the characteristics of materials. Although there is a great progress in thestudies of repair materials for bone defects, further investigations are warranted on how to produce highly biomimetic materials, optimize cell adhesion and migration, precisely control the expression and release of related genes and growth factors, validate clinical safety, and provide medical evidence in clinical practice.
