    Area of Science:

    • Biomaterials Science
    • Dental Education Technology

    Background:

    • Effective pre-clinical dental education requires realistic patient simulators.
    • Current models often lack the thermal properties of oral tissues, impacting material behavior simulation.

    Purpose of the Study:

    • To develop and evaluate a novel edentulous model that maintains human body temperature for enhanced dental training.
    • To assess the model's utility in demonstrating temperature-dependent properties of dental impression materials.

    Main Methods:

    • A new edentulous model was created with a soft, oral mucosa-mimicking material.
    • The model is designed to maintain human body temperature (approximately 37°C).
    • Heating time and energy consumption were recorded (4 minutes to reach temperature, 9 watts/hour).

    Main Results:

    • The model successfully reaches and maintains human body temperature.
    • The temperature-controlled surface allows for practical demonstrations of how ambient temperature influences impression material setting times.
    • The model's design is based on oral mucosa thickness.

    Conclusions:

    • This thermally regulated edentulous model offers a valuable tool for pre-clinical dental education.
    • It enhances the teaching of clinical characteristics of impression materials, particularly temperature-sensitive setting properties.
    • Future iterations aim to incorporate thermal and pressure sensors for a more sophisticated patient simulator.
