CALCIUM PHOSPHATE CEMENT: STUDY OF (BETA-TRICALCIUM PHOSPHATE, DICALCIUM PHOSPHATE AND CALCIUM CARBONATE SYSTEM
Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca3 (P04)2), dicalcium phosphate (DCP, CaHP04), calcium carbonate (Ca CO3), and hydroxylapatite (HAp, Ca10(P04)6(OH)2) as powder cement and disodium hydrogen phosphate (Na2HP04) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (...
متن کاملEffect of Gamma Radiation on Properties of a Calcium Phosphate-Calcium Sulfate Composite Cement
The present study investigates £-radiation effect on structure and selected properties of a tetracalcium phosphate (TTCP)/dicalcium phosphate anhydrous (DCPA)/calcium sulfate hemihydrate (CSH) cement immersed in Hanks’ solution. The results indicate that, at a dosage of 25 kGy, the working and setting times of the cement paste derived from £-ray-sterilized TTCP/DCPA/CSH powder did not change si...
متن کاملComparison of Phosphate Lowering Properties of Calcium Acetate and Calcium Carbonate in Hemodialysis Patients
Hyperphosphatemia has an important role in the development of secondary hyperparathyroidism and bone disease in patients with end-stage renal disease (ESRD). The most effective method of phosphate elimination lies with phosphate binders, the agent that more commonly used, calcium carbonate, is not an ideal binding agent. In this regard, calcium acetate has been reported to have more or at least...
متن کاملProperties of calcium carbonate-containing composite scaffolds.
Bone grafting in skeletal reconstruction has become a common task of orthopedic surgeon. Three-dimensional, porous, degradable scaffolds are often used to provide support while the new tissue can be formed in situ. There are numerous materials and techniques involved; however, each has certain drawbacks. One of the patented ceramic bone grafts is made of coral that has many benefits, e.g., its ...
متن کاملFabrication and characterisation of a calcium phosphate/zirconia composite
The aim of this study is to fabricate high strength calcium phosphate/ yttrium artially stabilised zirconia (Y-PSZ) composites using a simple powder pressing technique. Various compositions of hydroxyapatite and zirconia powder, ranging from 10 to 90 wt% Y-PSZ, were prepared using a wet mixing process. Ten compacts (13.5mm×3mm) were made for each composition, pressed and fired in air at sinte...
