The In Vitro Bioactivity, Degradation, and Cytotoxicity of Polymer-Derived Wollastonite-Diopside Glass-Ceramics
Ca-Mg silicates are receiving a growing interest in the field of bioceramics. In a previous study, wollastonite-diopside (WD) glass-ceramics were successfully prepared by a new processing route, consisting of the heat treatment of a silicone resin embedding reactive oxide particles and a Ca/Mg-rich glass. The in vitro degradation, bioactivity, and cell response of these new WD glass-ceramics, f...
متن کاملInduced crystallization porosity and properties of sintereds diopside and wollastonite glass-ceramics
diopside (CaO·MgO·2SiO2) and wollastonite (CaO·SiO2) glass-ceramics, forming ∼60% crystal phase and ∼40% albite-like Na2O·Al2O3·6SiO2) residual glass were studied. Two other diopside glass-ceramics with higher Na2O and Al2O3 content were also investigated. The phase formation was estimated by DTA, XRD and pycnometry, while the densification process was evaluated by porosity variations, ilatomet...
متن کاملPorous apatite-wollastonite glass-ceramic as an intramedullary plug.
We evaluated the efficacy and biocompatibility of porous apatite-wollastonite glass ceramic (AW-GC) as an intramedullary plug in total hip replacement (THR) for up to two years in 22 adult beagle dogs. Cylindrical porous AW-GC rods (70% porosity, mean pore size 200 microm) were prepared. Four dogs were killed at 1, 3, 6 and 12 months each and six at 24 months after implantation. Radiological ev...
متن کاملAn investigation on Mechanical Properties of Apatite-Wollastonite-Diopside Glass-Ceramics Composites
Apatite-wollastonite (A-W)-phlogopite glass-ceramic is considered to be difficult to resorb, but often, it has been incorporated in particulate form to create new bioactive composites for potential maxillofacial applications. With various compositions, the present work has attempted to prepare apatite-wollastonite (A-W)-phlogopite glass ceramic composites, by applying sintering. Here, three-poi...
متن کاملIn vitro evaluation of apatite/wollastonite glass–ceramic nano biocoatings on 316 alloys by plasma-sprayed
Among bioactive ceramics, the apatite/wollastonite (A/W) glass ceramic, containing apatite and wollastonite crystals in the glassy matrix, has been largely studied because of good bioactivity and used in some fields of medicine, especially in orthopedics and dentistry. However, medical applications of bioceramic are limited to non-load bearing applications because of their poor mechanical prope...
