    Summary
    This summary is machine-generated.

    This study introduces a magnetic sectional interim maxillary obturator. The device significantly reduced hypernasality and improved speech, mastication, and psychological state during rehabilitation.

    Area of Science:

    • Maxillofacial prosthodontics
    • Biomaterials engineering

    Background:

    • Maxillary defects often lead to speech and mastication impairments.
    • Existing obturator designs may lack sufficient retention and stability.
    • Magnetic retention offers a novel approach to enhance prosthesis function.

    Observation:

    • A sectional interim maxillary obturator was fabricated.
    • Retention was augmented using a magnetic system.
    • Speech and mastication were evaluated during prosthesis use.

    Findings:

    • A 32% decrease in hypernasality was observed during speech with the magnetic obturator.
    • The magnetic locking provided continuous retention.
    • Normal speech and mastication were enabled.

    Implications:

    • Magnetic retention can significantly improve outcomes for patients with maxillary defects.
    • This technique offers a viable solution for enhanced speech and mastication.
    • Improved function can lead to a better psychological state during rehabilitation.
