Surgical nasal prosthesis.

P E Hutcheson, A Udagama

    The Journal of Prosthetic Dentistry
    |January 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    This new method for fabricating immediate nasal prostheses uses RTV silicone rubber impressions, significantly reducing creation time. The resulting PVC prostheses are flexible, tissue-compatible, and minimize patient psychological distress.

    Area of Science:

    • Medical Device Fabrication
    • Prosthodontics
    • Materials Science

    Background:

    • Traditional methods for fabricating nasal prostheses are time-consuming.
    • Immediate prosthetic restoration is crucial for patient well-being post-excision.

    Observation:

    • Room Temperature Vulcanizing (RTV) silicone rubber impressions offer precise replication of excised nasal areas.
    • Polyvinyl Chloride (PVC) is a suitable material for flexible and tissue-compatible prostheses.

    Findings:

    • Utilizing RTV silicone impressions as refractory casts drastically cuts fabrication time from hours to minutes.
    • The RTV silicone impression serves as a mold for wax sculpting, streamlining definitive prosthesis creation.
    • PVC prostheses are surgically adaptable due to their softness and flexibility, ensuring good tissue integration.
