Microporous Ceramics Based on β-Tricalcium Phosphate

Chemical stability of grain boundaries in β-tricalcium phosphate ceramics

[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...

Enhancement of mechanical strength and in vivo cytocompatibility of porous β-tricalcium phosphate ceramics by gelatin coating

BACKGROUND In an attempt to prepare scaffolds with porosity and compressive strength as high as possible, we prepared porous β-tricalcium phosphate (TCP) scaffolds and coated them with regenerative medicine-grade gelatin. The effects of the gelatin coating on the compressive strength and in vivo osteoblast compatibility were investigated. METHODS Porous β-TCP scaffolds were prepared and coate...

Hydrogen-substituted β-tricalcium phosphate synthesized in organic media

β-Tricalcium phosphate (β-TCP) platelets synthesized in ethylene glycol offer interesting geometries for nano-structured composite bone substitutes but were never crystallographically analyzed. In this study, powder X-ray diffraction and Rietveld refinement revealed a discrepancy between the platelet structure and the known β-TCP crystal model. In contrast, a model featuring partial H for Ca su...

3D Powder Printed Bioglass and β-Tricalcium Phosphate Bone Scaffolds

The use of both bioglass (BG) and β tricalcium phosphate (β-TCP) for bone replacement applications has been studied extensively due to the materials' high biocompatibility and ability to resorb when implanted in the body. 3D printing has been explored as a fast and versatile technique for the fabrication of porous bone scaffolds. This project investigates the effects of using different combinat...
