Elastomeric 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...
متن کاملThe Dimensional Stability of Elastomeric Dental Impression Materials
High accuracy dental impression is usually a first step during fabrication of indirect restorations that have to be seated in or on prepared teeth. The dimensional stability of the impression material could have an influence on the accuracy of the final restoration. Elastomeric materials (additioncured silicones and condensationcured silicones) are most frequently used as the impression materia...
متن کاملA New Technique for Quality Assessment of Railway Ballast Materials
The influence of main quality tests on the overall quality of railway ballast materials is assessed in this study. The need to integrate all acceptance tests in a unified manner for precise evaluation of ballast quality is identified, and a technique of performing this is proposed. Using this approach, a new ballast quality index (BQI) is defined in which, the main acceptance tests including ab...
