2013/12/6
The apatite supergroup includes minerals with a generic chemical formula IXM12 VIIM23(IVTO4)3X (Z 2); chemically they can be phosphates, arsenates, vanadates, silicates, and sulphates. Themaximum sp...
Fabrication of carbonate apatite block based on internal dissolution-precipitation reaction of dicalcium phosphate and calcium carbonate
Carbonate apatite Dicalcium phosphate Calcium carbonate
2010/11/26
In this study, we investigated a novel method for fabrication of carbonate apatite block without ionic movement between precursor and solution by using precursor that includes all constituent ions of ...
Fabrication of Biporous Low-crystalline Apatite Based on Mannitol Dissolution from Apatite Cement
Apatite cement Porous Mannitol
2009/9/15
Biporous (macro- and microporous) calcium phosphate gains much attention as a bone substitute material because of its large surface area and that it improves cell penetration. In the present study, we...
Effects of Apatite Foam Combined with Platelet-rich Plasma on Regeneration of Bone Defect
Platelet-rich plasma Apatite foam Bone tissue regeneration
2009/9/14
The objective of this study was to investigate the regenerative effects of apatite foam (AF) combined with platelet-rich plasma (PRP) on bone defects. Critical-sized defects in the tibia of rats were ...
