Experimental Drillable Magnesium Phosphate Cement Is a Promising Alternative to Conventional Bone Cements

نویسندگان

چکیده

Clinically used mineral bone cements lack high strength values, absorbability and drillability. Therefore, magnesium phosphate have recently received increasing attention as they unify a mechanical performance with presumed degradation in vivo. To obtain drillable cement formulation, farringtonite (Mg3(PO4)2) oxide (MgO) were modified the setting retardant phytic acid (C6H18O24P6). In pre-testing series, 13 different compositions of analyzed concentrating on clinical demands for application. Of these composites, two formulations content (22.5 wt% 25 wt%) identified to meet demands. Both evaluated terms time, injectability, compressive strength, screw pullout tests biomechanical clinically relevant fracture model. The filler metaphyseal defect alone, combination screws drilled through cement. achieved time 5 min 30 s an injectability 100%. Compressive was shown be ~12–13 MPa overall displacement reduced <2 mm without screws. Maximum load until failure ~2600 N only ~3800 Two new revealed test set-ups add desired characteristics its such

Preparation and characterization of a degradable magnesium phosphate bone cement

A kind of degradable magnesium phosphate bone cement (MPBC) was fabricated by using the mixed powders of magnesium oxide (MgO), potassium dihydrogen phosphate (KH2PO4) and calcium dihydrogen phosphate (Ca(H2PO4)2.H2O). As MgKPO4, the main product of MgO and KH2PO4 was alkaline, the Ca(H2PO4)2.H2O was added to neutralize the alkali of the system. And the effects of Ca(H2PO4)2.H2O on the performa...

Guest Editors’ Introduction: A Promising Alternative to Conventional Silicon

FLEXIBLE ELECTRONICS ARE emerging as an alternative to conventional silicon electronics for large-area, low-cost applications such as rollable displays and TVs, e-papers, smart sensors, and disposable RFID tags. Through inexpensive manufacturing methods (e.g., ink-jet printing and roll-to-roll imprinting), flexible electronics can be printed on low-cost plastics. This advantage makes flexible e...

Preparation of Calcium Phosphate Cement and Polymethyl Methacrylate for Biological Composite Bone Cements

BACKGROUND We studied the biological safety, biomechanics, and tissue compatibility of calcium phosphate cement and Polymethyl Methacrylate composite bone cement mixed in different ratios. MATERIAL/METHODS CPC and PMMA were mixed in different ratios (3:1, 2:1, 1:1, 1:2, 1:5, 1:10, 1:15, and 1:20). PMMA solvent is a general solvent containing a dissolved preparation of the composite bone cemen...
