    A modified denture flask allows for precise three-piece ear mold production. This technique reduces stone fracture incidence, improving casting accuracy for custom ear prosthetics.

    Area of Science:

    • Dental prosthetics
    • Audiology
    • Materials science

    Background:

    • Conventional denture flasks are not optimized for three-piece ear mold fabrication.
    • Existing methods may lead to inaccuracies and material failure during casting.

    Purpose of the Study:

    • To present a method for modifying a standard large denture flask.
    • To enable the accommodation of three-piece ear molds within the modified flask.

    Main Methods:

    • Modification of a conventional large denture flask.
    • Utilizing the modified flask for three-piece ear mold casting.

    Main Results:

    • The modified flask successfully accommodates three-piece ear molds.
    • A decrease in the incidence of stone fracture during the casting process was observed.
