    Polysiloxane and polyether impression materials offer superior long-term dimensional stability and surface detail retention compared to silicone materials. Immediate pouring of impressions ensures the highest accuracy across all tested elastomeric materials.

    Area of Science:

    • Dental Materials Science
    • Polymer Chemistry

    Background:

    • Accurate dental impressions are crucial for fabricating prosthetics.
    • Dimensional stability of elastomeric impression materials is vital for long-term clinical success.
    • Non-aqueous elastomeric materials like silicones, polyethers, and polysiloxanes are commonly used.

    Purpose of the Study:

    • To evaluate the long-term dimensional stability of three non-aqueous elastomeric impression materials.
    • To compare the surface detail reproduction of silicone, polyether, and polysiloxane materials over time.
    • To identify the most dimensionally stable and accurate impression material for dental applications.

    Main Methods:

    • Utilized an A.D.A. specification No. 19 test block and mould for impression material testing.
    • Measured dimensional changes using a travelling stage reflecting microscope and Quantimet 720 Image Analyzing computer.

  • Recorded measurements at multiple time points: immediately, 4, 24, 48 hours, and 1, 2, 3, 4 weeks.

    • Main Results:

    • Impressions poured immediately exhibited the greatest accuracy for all tested materials.
    • Polysiloxane (0.025 mm) and polyether (0.033 mm) showed minimal dimensional changes after 4 weeks.
    • Silicone demonstrated significant dimensional changes (0.14 mm at 4h, 0.2 mm at 4 weeks) and substantial loss of surface detail within 24 hours.

    Conclusions:

    • Polysiloxane and polyether impression materials offer superior long-term dimensional stability compared to silicone.
    • Polysiloxane provides the best surface detail retention after 4 weeks, followed by polyether.
    • Material selection significantly impacts the accuracy and longevity of dental impressions.
