Characterization of bone cements.

摘要: Properties of acrylic bone cements during and after curing were determined for three brands cement. Curing time consistency chosen the characterization handling working behavior these materials. The performance may be related amongst other things to following properties: water resorption, solubility/disintegration, flexural modulus elasticity, yield stress, proportional limit, strength impact strength. Methods determine material properties are described. influence radiopacifying antibiotic additives on is evaluated as well porosity results indicate that considerable differences in occur. tested do not show marked differences. Radiopacifying appear have a negative effect properties; it develops under simulated clinical conditions more pronounced.
