Elastomeric dental impression materials- polyether has best penetration ability and polyvinylsiloxane has highest tensile strength: study

The Results of the study are: 

• Polyether showed the best extension into all widths of simulated sulcus followed by vinylsiloxanether and polyvinylsiloxane, respectively.
• PVS was significantly higher in tensile strength than VSE and polyether, while vinylsiloxanether was significantly higher than polyether.

Thus, penetration ability of elastomeric dental impression materials was depended on gingival sulcus width. The wider the sulcular width, the better the penetration ability of elastomeric dental impression materials. Polyether presented the best penetration ability, while the novel polyvinylsiloxane showed highest tensile strength.
