    Area of Science:

    • Biomaterials Engineering
    • Prosthetics and Orthotics

    Background:

    • Traditional obturator fabrication can be time-consuming and result in heavy prostheses.
    • Material selection significantly impacts prosthesis weight, strength, and repairability.

    Purpose of the Study:

    • To investigate the use of polyurethane foam as a core material for lightweight obturator fabrication.
    • To evaluate the impact of polyurethane foam on prosthesis weight, strength, and ease of repair.

    Main Methods:

    • Fabrication of an obturator using polyurethane foam as the core structural material.
    • Assessment of the resulting prosthesis for weight reduction, strength, and repair efficiency.

    Main Results:

    • Polyurethane foam effectively reduced the overall weight of the obturator.
    • The fabricated obturator demonstrated increased strength compared to conventional methods.
    • The use of polyurethane foam facilitated easier and quicker repairs.

    Conclusions:

    • Polyurethane foam is a viable and advantageous core material for lightweight obturator fabrication.
    • This method offers significant benefits in terms of weight reduction, enhanced strength, and simplified repair of prostheses.
    • The technique presents a time-saving approach in prosthetic device manufacturing.
