Abstract:

BACKGROUND: Titanium alloy quality was light and density was low. Titanium alloy has the characteristics of anti-electrochemical corrosion, good biocompatibility, low elastic modulus and high intensity, and has been extensively used in stomatology.
OBJECTIVE: To summarize the clinical application progress of oral biomaterial titanium alloy implant.
METHODS: We retrieved Vip Database for articles concerning oral biomaterial titanium alloy implant published from January 1998 to October 2010. The key words were “titanium alloy, implant, biocompatibility”.
RESULTS AND CONCLUSION: At present, numerous studies have addressed biocompatibility of titanium alloy implant. Scholars tried to seek ideal surface structure of titanium alloy implant to elevate the osseointegration ability of implant. This plays an important role in formation of osseointegrated interface of implant. Surface treatment of titanium alloy implant exerts a crucial effect on implant successful rate. Different treatment methods have their advantages, but their common characteristic is to form crude surface and to improve biological activity and osseointegration ability. Therefore, to seek a surface treatment method that has various advantages and contributes to osseointegration has been a hot point in the recent study of oral implant.
