    Area of Science:

    • Dental Materials Science
    • Biomaterials Engineering

    Background:

    • Accurate interocclusal records are essential for prosthodontic treatment planning.
    • Evaluating the physical and mechanical properties of recording materials is critical for clinical success.

    Purpose of the Study:

    • To assess the resistance to closure, working time, and dimensional stability of various interocclusal recording materials.
    • To determine the long-term reliability of elastomers under specific storage conditions.

    Main Methods:

    • Investigated the initial resistance to closure and working time of different elastomer materials.
    • Measured the volumetric contraction during polymerization and dimensional stability of rigid materials (acrylic resin, zinc oxide pastes).
    • Assessed the reliability of elastomers after storage in sealed plastic bags.

    Main Results:

    • All elastomers demonstrated a rapid increase in working time and initial resistance to closure ranging from 0.5 N to 13.8 N.
    • Wax exhibited approximately 7 N resistance at 60°C.
    • Elastomers showed clinically insignificant volumetric contraction during polymerization.
    • Rigid materials like acrylic resin and zinc oxide pastes displayed good dimensional stability.
    • Stored elastomers maintained their reliability over an extended period in sealed plastic bags.

    Conclusions:

    • Elastomeric interocclusal recording materials exhibit favorable working characteristics and dimensional stability.
    • Proper storage is key to maintaining the long-term reliability of elastomers for dental use.
    • These findings support the use of elastomers in clinical settings requiring precise interocclusal registrations.
