Abstract In this study, high-resolution transmission electron microscopy (HRTEM) was employed to characterize the nanostructure of strontium-substituted hydroxyapatite (Sr-HA) and its evolution following in vitro immersion in physiological solutions. HRTEM images showed that the substitution of Sr induced local distortions in the hydroxyapatite (HA) lattice: minor levels of edge dislocations were detected at low doping contents of Sr ions (1 at%); when the Sr content exceeded 10 at%, the… Expand

Ultrastructural comparison of dissolution and apatite precipitation on hydroxyapatite and silicon-substituted hydroxyapatite in vitro and in vivo.
It is suggested that proteins in the in vivo milieu modify the processes of dissolution from the implant, which predominates at the crystallite surfaces in SBF, whereas grain boundary dissolution predominates in vivo. Expand
Crystal dissolution of biological and ceramic apatites
This study provides for the first time, information on the dissolution process of implanted ceramic HA crystals and suggests that the crystal defects resulting from the sintering processes during the preparation of ceramic HA affect its in vivo degradation and performance. Expand
Comparison of in vivo dissolution processes in hydroxyapatite and silicon-substituted hydroxyapatite bioceramics.
High-resolution transmission electron microscopy observations confirmed that defects, in particular those involving grain boundaries, were the starting point of dissolution in vivo and may help to explain the mechanism by which silicate ions increase the in vivo bioactivity of pure HA. Expand
Chemical composition, crystal size and lattice structural changes after incorporation of strontium into biomimetic apatite.
The findings from this work indicate that current clinical dosage which usually results in Sr incorporation of below 1.5% may not change chemical composition and lattice structure of bone, while it will broaden the bone crystal size distribution and strengthen the bone. Expand
Effect of carbonate substitution on the ultrastructural characteristics of hydroxyapatite implants

The structure of strontium-doped hydroxyapatite: an experimental and theoretical study.
Density functional theory periodic band-structure calculations indicate that the Ca2+ to Sr2+ substitution induces strong local distortion on the hydroxyapatite lattice: the nearest neighbor Sr-O bond structures in both cationic sites are comparable to pure SrHA, while Sr induces more distortion at site 2 than site 1.
