Abstract:

BACKGROUND: Currently, the mechanism by which calcium phosphate ceramics induces osteogenesis is not fully understood, and many scholars have tried to expound the mechanism from the perspective of the structural properties.

OBJECTIVE: To review how the structural properties of calcium phosphate ceramics affect their osteoinductive activity.
METHODS: The PubMed database and Google academic database (1997-01/2015-03) were searched to retrieve the related articles about the structural properties of calcium phosphate ceramics affecting their osteoinductive activity. After the articles with outdated reviews or repetitive contents were ruled out, 60 articles were suitable for further analysis and review.
RESULTS AND CONCLUSION: The structural properties of calcium phosphate ceramics are displayed by macrostructure, such as macropores, holes, pipes and space between particles, and microstructure, such as micropore, particle size, surface roughness, specific surface area. Each parameter of the structural properties affects the bioactivities of calcium phosphate ceramics in some way, which renders their abilities of inducing osteogenesis to arise from nothing or change from weakly to strongly. Apart from structure design, physical and chemical properties of calcium phosphate ceramics will also affect its biological activity in vivo. Therefore, the physicochemical properties of calcium phosphate ceramics should be considered in the structure design in order to achieve an optimal osteoinductive activity.
