Mechanical Properties of Elastomeric Impression Materials mechanical properties of elastomeric impression materials

Nov 26, 2015Adequate mechanical properties ensure that the impression material can withstand various stresses upon removal, while maintaining dimensional stability and integrity. The tear of elastomeric materials is a mechanical rupture process initiated and propagated at a site of high stress concentration caused by cut, defect, or localized deformation. Viscoelastic properties of elastomeric impression mechanical properties of elastomeric impression materialsCreep compliance measurements were shown to be effective in characterizing the elastic, retarded elastic, and viscous properties of polysulphide, silicone, and polyether impression materials. The test is particularly valuable in that the creep compliance was independent of load, allowing the mechanical properties to be represented by a single total creep compliance curve which can be used to mechanical properties of elastomeric impression materials

1. Introduction - Hindawi

The ideal impression material should exhibit adequate mechanical properties to withstand stresses under various clinical scenarios. Elastomeric impression materials offer high elastic recovery and acceptable flexibility on removal of the impression from the mouth [6]. Recently, new elastomeric impression materials have been introduced, with the mechanical properties of elastomeric impression materials2. Materials and Methods8 Impression Materials Pocket DentistryJan 01, 2015Mechanical Properties The set impression materials can be rigid (inelastic) or elastic. A set rigid material is highly resistant to flexure, and it fractures suddenly when stressed, in a manner similar to that of chalk. Material is not flexible and will fracture when deformed, like chalk.
