Method of contraction and polymerisation temperature testing for surgical cement

This work concentrates on the developing a method of the contraction and polymerisation temperature testing for the surgical cement. The linear contraction and maximum polymerisation temperature values have been determined for the pure Palacos R cement and for the same cement with Al2O3 admixture. The investigations were performed into metal mould at initial temperature 19 °C and 37 °C. Basing on the examination results it can be stated that on the contraction and polymerisation temperature the following factors have the influence: - temperature of the mould, - kind of the admixture, - a size of the admixture particles.
