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 کاملDose-dependent modulation of octacalcium phosphate crystal habit by amelogenins.
In vitro studies on interactions between amelogenins and calcium phosphate crystals are critical for elucidating biomineralization mechanisms of tooth enamel. This work was aimed at investigating the effects of native porcine amelogenins on octacalcium phosphate (OCP) crystal growth in a gelatin gel. We prepared OCP mineral discs by circulating calcium and phosphate solutions on the opposite en...
متن کاملAn Octacalcium Phosphate Forming Cement
The osteoconductive and possibly osteoinductive characteristics of OCP increased the interest in preparation of bone graft materials that contain OCP in its composition. Calcium phosphate cements (CPCs) were prepared using a mixture of α-tricalcium phosphate (α-TCP) and dicalcium phosphate anhydrous (DCPA), with α-TCP / DCPA molar ratio of 1/1 and distilled water or 0.5 mol / L phosphate aqueou...
متن کامل3D Printing of Octacalcium Phosphate Bone Substitutes
Biocompatible calcium phosphate ceramic grafts are able of supporting new bone formation in appropriate environment. The major limitation of these materials usage for medical implants is the absence of accessible methods for their patient-specific fabrication. 3D printing methodology is an excellent approach to overcome the limitation supporting effective and fast fabrication of individual comp...
متن کاملQuality control of synovial fluid crystal identification.
OBJECTIVE To establish a quality assessment programme for the diagnosis of crystal arthropathies by synovial fluid (SF) microscopy. METHODS Three or four cytocentrifuge slides prepared from suitable patient SF specimens were distributed to 25-47 predominantly Finnish clinical laboratories once a year. Sodium urate crystals were included in every survey. RESULTS Returns for the years 1989-19...
