Abstract:

BACKGROUND: As one of the important bone substitute materials in bone tissue engineering, α-tricalcium phosphate (α-TCP) has been widely applied and researched.
OBJECTIVE: To introduce the newest research progress about α-TCP as a kind of bone substitute material, and to prospect its development.
METHODS: The first author searched the relative literatures addressing α-TCP as a bone substitute material published from January 1965 to August 2015 in PubMed, FMJS, CNKI, Wanfang and CBM databases. The keywords were “alpha tricalcium phosphate, composite material, bone graft, bone substitution material” in English and Chinese, respectively. According to the inclusion and exclusion criteria, finally 42 articles were reviewed.
RESULTS AND CONCLUSION: α-TCP is one of calcium phosphate compounds which has been extensively applied and researched. It holds good bioactivity, biocompatibility, biodegradability, biodegradation and osteoconductivity except osteoinduction. Therefore, combining α-TCP with inorganic or organic factors to establish the composite material cannot only overcome the shortage of α-TCP in physicochemical characteristics, but also provide a mixed material with better resilience that is easy for cells to adhere, shorten bone reconstruction time, and even can carry antibacterial drugs. All these improvements will markedly shorten the bone repair time and provide a new idea for future development of bone graft materials.
