Journal ArticleDOI
A comparative study of calcium phosphate formation on bioceramics in vitro and in vivo
TL;DR: Investigation of formation of calcium phosphate on various bioceramic surfaces in simulated body fluid (SBF) and in rabbit muscle sites showed that ability of inducing Ca-P formation in SBF was similar amongBioceramics, but considerably varied among biocers in vivo.
Journal ArticleDOI
Dissolution and mineralization behaviors of HA coatings.
TL;DR: HA coatings were characterized by X-ray diffraction, scanning electron microscope, and Fourier transform infrared spectra before and after immersion in simulated body fluid (SBF); both dissolution and precipitation occurred at the same time, but the kinetics of dissolution was quite different from that of precipitation.
Journal ArticleDOI
A comparative study of electrochemical deposition and biomimetic deposition of calcium phosphate on porous titanium
Qiyi Zhang,Yang Leng,Renlong Xin +2 more
TL;DR: This study investigated the effectiveness of two coating methods: biomimetic deposition (BD) and electrochemical deposition (ED) in aqueous solutions to enhance titanium's osteoinduction capability.
Journal ArticleDOI
Electrochemical activation of titanium for biomimetic coating of calcium phosphate.
Qiyi Zhang,Yang Leng +1 more
TL;DR: A new method to activate surfaces of metal implants for osseointegration, which is considerably faster than treatments currently in use, such as alkaline treatment, is explored.
Journal ArticleDOI
Spectroscopic analysis of titanium surface functional groups under various surface modification and their behaviors in vitro and in vivo.

TL;DR: The ToF-SIMS analysis demonstrated the TiOH+/Ti+ ratios of various surfaces correlated well with the bioactivity and the surface energies, which implied that Ti-OH could play an important role in theBioactivity.
