Polydimethylsiloxane button obturator for hard palate clefts.

S Taicher, M Sela

    The Journal of Prosthetic Dentistry
    |January 1, 1986
    PubMed
    Summary

    A novel polydimethylsiloxane obturator offers a stable and retentive solution for hard palate clefts. This soft obturator utilizes nasal cavity undercuts, ensuring a secure fit while covering minimal palatal area.

    Area of Science:

    • Biomaterials Science
    • Craniofacial Surgery
    • Pediatric Dentistry

    Background:

    • Congenital anomalies of the hard palate, such as cleft palate, present significant challenges in pediatric care.
    • Existing obturator designs may face limitations in retention, stability, and patient comfort.
    • The need for biocompatible and effective prosthetic devices for hard palate reconstruction is critical.

    Purpose of the Study:

    • To describe a novel polydimethylsiloxane obturator designed for hard palate clefts.
    • To evaluate the retention and stability of this obturator using natural anatomic features.
    • To highlight the material's safety profile for pediatric use.

    Main Methods:

    • Fabrication of a polydimethylsiloxane obturator tailored for hard palate defects.
    • Utilizing the inherent anatomic undercuts of the nasal cavity for device retention.
    • Clinical assessment of the obturator's fit, stability, and coverage.

    Main Results:

    • The soft polydimethylsiloxane obturator demonstrated effective retention and stability.
    • Anatomic undercuts of the nasal cavity were successfully leveraged for device fixation.
    • The obturator covered a limited portion of the hard palate, preserving oral space.

    Conclusions:

    • Polydimethylsiloxane is a suitable material for fabricating retentive and stable obturators for hard palate clefts.
    • The described obturator design offers a minimally invasive prosthetic solution.
    • The nontoxic and noncarcinogenic nature of the material ensures patient safety.
