| Abstract: | AIM:To analyze constructive and biomechanical properties of different quality ratio material impregnated decalcified bone matrix(DBM) with bone cement(BC).METHODS:The DBM particles and the materials impregnated 0mg/g,300mg/g and 400mg/g mass ratio DBM particles with BC were made according to the methods of Urist et al.The compound material constructions were observed by scanning electron microscope and the biomechanical properties were measured by Instron mechanics test-ing-machine.RESULTS:The DBM particles with irregular gaps existing within interspace were connected with BC by the multipoint mode in the compound material.The ultimate compressive strength were 0mg/g DBM in (59.3&;#177;2.2)MPa,300mg/g in(27.1&;#177;1.8)MPa,400mg/g in (19.3&;#177;1.6)MPa.The ultimate bending strength were 0mg/g in (54.3&;#177;3.7)MPa,300mg/g in (18.5&;#177;1.1)MPa,400mg/g in (13.3&;#177;1.4)MPa.CONCLUSION:The materials of DBM impregnated with BC had perfect plastic property with much more irregular gaps existing within interspace.The materials could provide abundant biomechanical support. |
