    Choosing the right dental impression materials and techniques minimizes working model distortion. Lower strain materials with the two-phase technique or higher strain materials with the wash technique yield the most accurate dental models.

    Area of Science:

    • Dental Materials Science
    • Prosthodontics
    • Biomaterials Engineering

    Background:

    • Accurate working models are crucial for fabricating well-fitting dentures.
    • Impression material properties and techniques can influence model accuracy.
    • Understanding these influences is key to improving prosthetic outcomes.

    Purpose of the Study:

    • To investigate the impact of impression material strain levels and impression techniques on working model distortion.
    • To evaluate how cervical spillway size affects model accuracy.
    • To identify optimal combinations of material properties and techniques for minimizing distortion.

    Main Methods:

    • Working models were created using putty-type impression materials with varying strain levels (Reprosil, Express, Exaflex).

  • Different cervical spillway sizes (2mm, 9mm) and impression techniques (two-phase, wash) were employed.
  • A three-dimensional measuring system was used to quantify model distortion.

    • Main Results:

    • Low strain materials with the two-phase technique and high strain materials with the wash technique produced models closest to the master model.
    • A small cervical spillway reduced variations in abutment tooth distance and diameter, and alveolar ridge distortion.
    • Impression material strain, spillway size, and technique did not affect vertical (Y-axis) deviation.

    Conclusions:

    • The two-phase technique with low strain materials or the wash technique with high strain materials are recommended for minimizing abutment tooth distortion.
    • Cervical spillway size significantly impacts the accuracy of specific dental arch measurements.
    • Optimizing impression procedures is essential for achieving high-fidelity dental prosthetics.
