Influence of the sintering atmosphere on the physico-chemical properties and the osteoclastic resorption of β-tricalcium phosphate cylinders

Paul Bowen, Duncan Thomas Lindsay Alexander, Gabrielle Anne Laguisma Sblendorio

One of the most widely used materials for bone graft substitution is β-Tricalcium phosphate (β-TCP;β- Ca3(PO4)2). beta-TCP is typically produced by sintering in air or vacuum. During this process, evaporation of phosphorus ...

Towards an improved understanding of the β-TCP crystal structure by means of “checkerboard” atomistic simulations

Paul Bowen, Duncan Thomas Lindsay Alexander, Gabrielle Anne Laguisma Sblendorio

The large variability of biological responses to beta-TCP implants reported in the literature could possibly be related to subtle differences in the beta-TCP crystal structure. The structure contains one partially occupied site Ca(4). In order to better un ...

Effect of minor amounts of beta-calcium pyrophosphate and hydroxyapatite on the physico-chemical properties and osteoclastic resorption of beta-tricalcium phosphate cylinders

Paul Bowen, Gabrielle Anne Laguisma Sblendorio

beta-Tricalcium Phosphate (beta-TCP), one of the most used bone graft substitutes, may contain up to 5 wt% foreign phase according to standards. Typical foreign phases include beta-calcium pyrophosphate (beta-CPP) and hydroxyapatite (HA). Currently, the ef ...

Chemically pure beta-tricalcium phosphate powders: Evidence of two crystal structures

Paul Bowen, Duncan Thomas Lindsay Alexander, Gabrielle Anne Laguisma Sblendorio

The question whether beta-tricalcium phosphate (beta-TCP) can form a solid solution with beta-calcium pyrophosphate (beta-CPP) and/or hydroxyapatite (HA) has still not been solved. For this reason, wet-chemically synthesized beta-TCP powders with only 20 p ...

Atomistic simulation and electron microscopy to characterize grain boundaries in doped beta-tricalcium phosphate ceramics

Gabrielle Anne Laguisma Sblendorio

The limitations and potential complications correlated with autogenous bone grafts have raised interest in the development of synthetic bone graft substitutes. ß-tricalcium phosphate (ß-TCP) is one of the most promising materials for synthetic bone graft s ...
