In vivo changes of nanoapatite crystals during bone ... - Science
2019年11月13日 · Hydroxyapatite (HA) plays an important role in clinical bone repair. However, it remains a challenge to accurately determine its changes during bone reconstruction and to identify its differences from native bone apatite. Here, terbium (Tb) doped uniform HA nanocrystals were implanted into bone tissue and compared with native bone apatite.
Transformation of amorphous calcium phosphate to bone-like apatite - Nature
2018年10月9日 · Herein, we demonstrate a detailed transformation mechanism of amorphous calcium phosphate spherical particles to apatite platelet-like crystals, within the confined nanodomains of a...
Recent Trends in Hydroxyapatite Supplementation for …
This review presents an up-to-date literature overview of the various uses of hydroxyapatite as a biocompatible material for bone regeneration, the connection between the roles of bone cells and hydroxyapatite, the role of signaling pathways on bone development, several methods for the synthesis of hydroxyapatite and the various combinations ...
Carbonate apatite artificial bone - PMC - PubMed Central (PMC)
In this paper, methods of fabricating CO 3 Ap artificial bone are reviewed along with their clinical and animal results. CO 3 Ap artificial bone is resorbed by osteoclasts and upregulates the differentiation of osteoblasts. As a result, CO 3 Ap demonstrates much higher osteoconductivity than HAp and is replaced by new bone via bone remodeling.
A mineralogical perspective on the apatite in bone
2005年4月28日 · In this paper, we show how a mineralogic approach to bone can provide insights into the resorption–precipitation processes of bone development, the exceedingly small size of bone crystallites, and the body's ability to (bio)chemically control the properties of bone.
Physical and Histological Comparison of Hydroxyapatite, …
2018年10月16日 · Three commercially available artificial bone substitutes with different compositions, hydroxyapatite (HAp; Neobone ®), carbonate apatite (CO 3 Ap; Cytrans ®), and β-tricalcium phosphate (β-TCP; Cerasorb ®), were compared with respect to their physical properties and tissue response to bone, using hybrid dogs.
Ionic substituted hydroxyapatite for bone regeneration applications…
2021年6月1日 · Biological apatites are characterised by various ionic substitutions within the HAp lattice that are crucial for bone metabolism. The introduction of key role elements within synthetic calcium phosphates (CaP), mainly hydroxyapatite (HAp), can increase osteogenesis and enhance bone regeneration process.
