Viscoelastic properties of elastomeric impression materials: polysulphide, silicone and polyether rubbers.
Creep 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 de...
متن کاملViscoelastic properties of silicone, polysulfide, and polyether impression materials.
The viscoelastic properties of nine silicone-, polysulfide-, and polyether-based impression materials were determined using creep tests. During deformation the materials demonstrated linear viscoelastic behavior. The creep compliance curves, recovery, and percent set were calculated. Permanent deformation in these materials is a result of lack of recovery of elastic deformation as well as visco...
متن کاملElastomeric impression materials: a comparison of accuracy of multiple pours.
AIM The aim of the present study is to compare the various elastomeric impression materials in terms of accuracy and dimensional stability, with respect to obtaining multiple casts from a single elastomeric impression at various times of pours. MATERIALS AND METHODS Three master dies were prepared for the impression making, two of these were made of brass containing a central hole with underc...
متن کاملAccuracy of newly formulated fast-setting elastomeric impression materials.
STATEMENT OF PROBLEM Elastomeric impression materials have been reformulated to achieve a faster set. The accuracy of fast-setting elastomeric impression materials should be confirmed, particularly with respect to disinfection. PURPOSE The purpose of this study was to assess the accuracy of 2 types of fast-setting impression materials when disinfected with acid glutaraldehyde. MATERIAL AND ...
متن کاملLinear dimensional stability of elastomeric impression materials over time.
UNLABELLED The purpose of this study was to evaluate the linear dimensional stability of different elastomeric impression materials over time. A metal mold was designed with its custom trays, which were made of thermoplastic sheets (Sabilex sheets 0.125 mm thick). Three impressions were taken of it with each of the following: the polyvinylsiloxane Examix-GC-(AdEx), Aquasil-Dentsply-(AdAq) and P...
