Elastomeric impression materials (addition silicones and polyethers) offer high elastic recovery and acceptable flexibility on removal of the impression from the mouth. Elastomeric materials (addition- cured silicones and condensation- cured silico- nes) are most frequently used as the impression material in fixed prosthodontics. BACKGROUND: The aim of this study was to compare a conventional technique (elastomeric impression material - EIM) and a digital technique (scanner digital model - SDM) on a six-analog master model (MM) to determine which was the most exact. In the present study, the lack of significant differences between these two types of elastomeric impression materials under this testing suggested that both of these materials can reproduce the required details. The light-body vinylpolyether silicone showed high tensile strength, yield strength, and adequate strain at yield/brake; those features might help to reduce tearing phenomena in the thin interproximal and crevicular areas.
