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 کاملDifference in Osteoclast Responses to Tricalcium Phosphate in Culture Medium Supplemented with Zinc and to Zinc-Containing Tricalcium Phosphate
Difference in osteoclast responses (i.e., apoptosis, actin ring formation) to tricalcium phosphate (TCP) in culture medium supplemented with zinc and to zinc-containing tricalcium phosphate (ZnTCP) was investigated in this study. On the TCP ceramic, an increase in zinc ion in the culture medium within the range between 0.3 and 6.8 ppm significantly induced an increase in osteoclast apoptosis an...
متن کاملTricalcium phosphate (α-TCP) and polymethylmethacrylate (PMMA) implantation
Bone loss induced by inflammation is one of the complications after biomaterial implantation. There is no much data on expression of cytokines and defensins into the bone tissue around the implants in literature. The aim of this work was to investigate the distribution and appearance of interleukin (IL)-1, IL-6, IL-8, IL10 and β – defensin (BD)-2, BD-3, BD-4 after the implantation of different ...
متن کاملElaboration and Characterization of Alumina-Tricalcium Phosphate Composites
The effect of -tricalcium phosphate additive on the alumina matrix was investigated. The sintering behaviour of the alumina tricalcium phosphate composites was characterized by using magic angle spinning nuclear magnetic resonance, X-ray diffraction, dilatometry, differential thermal analysis and scanning electron microscopy analysis. The mechanical properties of composites have been investiga...
متن کاملa - and b - tricalcium phosphate : A density functional study
Biologically important aand b-tricalcium phosphates ~TCPs! have been investigated using ab initio density functional calculations. aand b-TCP have particularly large unit cells amounting to 312 and 273 atoms, respectively. The relationship between a-TCP and its three subcells, as well as the influence of the distribution of the Ca vacancies apparently existing in b-TCP have been studied. The ca...
