Abstract
The expansion-contraction and temperature properties of PMMA from various manufacturers under simulated in situ conditions were investigated. In a constrained expansion test all PMMA cements showed a net volumetric contraction. The differences in maximum temperature, time to reach maximum temperature, initial contraction, and net volumetric change, were significantly different for all the cements tested. All cements followed a general form of expansion with an initial contraction, an expansion and then another contraction with a constant volume occurring between the initial contraction and the expansion for at least 2 minutes in all cements. It is suggested that the surgeon be aware of the differences in the various cements and he make use of the constant volume plateau before full polymerization. By waiting until the initial contraction is completed and inserting the cement during the constant volume plateau, the surgeon will be able to obtain a net expansion and thus enhance the mechanical interlocking of the cement and trabeculae.
