Tricalcium Phosphate Ceramics Complexed with Hydroxyapatite

Development and Evaluation of Superporous Ceramics Bone Tissue Scaffold Materials with Triple Pore Structure A) Hydroxyapatite, B) Beta-Tricalcium Phosphate

Hydroxyapatite ceramics (HAp) have been used as bone graft materials, due to their excellent biocompatibility and osteoconductivity. Moreover, they had a wide range of porosity for using various bone defect parts. For example, HAp from 0 to 15 % porosity with high strength was useful as an ilium spacer, intervertebral spacer which requires high strength. HAp from 30 to 40% porosity was useful a...

Chemical stability of grain boundaries in β-tricalcium phosphate ceramics

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-...

Hydroxyapatite and Hydroxyapatite-Based Ceramics

Data are summarized on the synthesis of hydroxyapatite (HA) by wet-chemical processes, solidstate reactions, and hydrothermal treatment. The conditions for HA preparation via precipitation from solutions of calcium chloride, dibasic ammonium phosphate, and aqueous ammonia are discussed at length. Detailed analysis of the fabrication and properties of calcium-phosphate-based ceramics is presente...

[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...
