Abstract:

BACKGROUND: Ti6Al4V is a titanium alloy that is widely used in human joint replacement, but its modulus of elasticity is greater than human bone, resulting in the bad stability of the prosthesis. Ti35Nb3Zr2Ta, a new β titanium alloy, has a lower modulus of elasticity, and maybe becomes a new-generation human joint prosthesis material that has a better biocompatibility.

OBJECTIVE: To study the biocompatibility of Ti35Nb3Zr2Ta in prosthesis.

METHODS: Wanfang, CNKI and PubMed databases were retrieved using a computer with “new β titanium; prosthesis; biocompatible” as keywords, and the retrieval time ranged from 2010 to 2015. Articles focusing on current application status for medical prosthesis materials and the biocompatibility of Ti35Nb3Zr2Ta in prosthesis were selected.

RESULTS AND CONCLUSION: Compared with Ti6Al4V, Ti35Nb3Zr2Ta has higher surface roughness and smaller surface contact angle; the alkaline phosphatase activity and amount of calcium deposits in osteoblasts cultured at Ti35Nb3Zr2Ta is significantly higher than that at Ti6Al4V. Ti35Nb3Zr2Ta has good biocompatibility, and can be considered to be widely used as joint prosthesis material further.
