Characterization of Bone Cements [PDF]

Acta Orthopaedica Scandinavica, 1975
Properties of acrylic bone cements during and after curing were determined for three brands of bone cement. Curing time and consistency were chosen for the characterization of the handling and working behavior of these materials. The performance of bone cements after curing may be related amongst other things to the following properties: water ...
