Biocompatibility of biphasic α,β-tricalcium phosphate ceramics in vitro

Chemical stability of grain boundaries in β-tricalcium phosphate ceramics

Laser Machining and In Vitro Assessment of Wollastonite-Tricalcium Phosphate Eutectic Glasses and Glass-Ceramics

Bioactivity and ingrowth of ceramic implants is commonly enhanced by a suitable interconnected porous network. In this work, the laser machining of CaSiO₃‒Ca₃(PO₄)₂ biocompatible eutectic glass-ceramics and glasses was studied. For this purpose, 300 µm diameter craters were machined by using pulsed laser radiation at 532 nm with a pulsewidth in the nanosecond range. Machined samples were soaked...

The thermal stability of hydroxyapatite in biphasic calcium phosphate ceramics.

Biphasic calcium phosphate ceramics (BCP) comprising a mix of non-resorbable hydroxyapatite (HA) and resorbable beta-tricalcium phosphate (beta-TCP) are particularly suitable materials for synthetic bone substitute applications. In this study, HA synthesised by solid state reaction was mechanically mixed with beta-TCP, then sintered to form a suite of BCP materials with a wide range of HA/beta-...

[Application of calcium phosphate ceramics to periodontal therapy. 2. Fundamental studies on tricalcium phosphate (TCP)].

To decide the application of tricalcium phosphate (TCP)to periodontal therapy, following fundamental studies on TCP were performed. Materials used were six kinds of TCPs of which firing temperature were 900 • Ž(LT)and 1,100 • Ž (HT), and diameter were less than 100,um(size S), 200 • `300,ƒÊm(size M)and 500 • `1,000,um(size L). To investigate the surface ultrastructure of the 'rCP with different...

In vitro ion adsorption and cytocompatibility of dicalcium phosphate ceramics

BACKGROUND In vitro cell testing of degradable bioceramics such as brushite or monetite is often challenging due to the ion release into or adsorption from the culture medium. These ionic changes are then mostly responsible for cell proliferation and activity, which prohibits the investigation of effects originating from surface topography or further material modifications. METHODS Here, we a...
