    Patients with complete dentures may experience speech issues due to altered tactile feedback. Adding specific textured features to dentures can help improve speech clarity and patient satisfaction.

    Area of Science:

    • Prosthodontics
    • Speech Pathology
    • Biomedical Engineering

    Background:

    • Complete dentures can alter speech production due to changes in oral anatomy and tactile sensation.
    • Patients may experience difficulties with speech clarity, particularly with consonant sounds, after denture insertion.
    • Loss of tactile feedback and turbulence in airflow are key factors affecting speech in denture wearers.

    Purpose of the Study:

    • To identify potential structural modifications on complete dentures that can aid in improving speech for patients.
    • To explore methods for enhancing tactile location skills and restoring airflow turbulence for better speech articulation.
    • To investigate the effectiveness of specific denture modifications in addressing speech problems in the absence of pathology.

    Main Methods:

    Related Experiment Videos

    • Review of existing literature on denture-related speech impediments and tactile sensation.
    • Conceptual design of denture modifications, including nonanatomic papilla, rugae-like papilla, roughened regions, and indentations.
    • Emphasis on the placement of these features posterior to the incisive papilla for optimal tongue guidance.
    • Highlighting the importance of collaboration with speech pathologists for planning and evaluation.

    Main Results:

    • Proposed denture modifications aim to provide tactile cues for tongue positioning and airflow management.
    • Textured features can potentially compensate for diminished tactile location skills.
    • The effectiveness of these modifications is dependent on precise placement and individual patient adaptation.
    • Cooperation with speech pathologists is crucial for successful implementation and assessment.

    Conclusions:

    • Specific, strategically placed textured modifications on complete dentures can potentially improve speech.
    • These modifications may help restore tactile feedback and airflow dynamics essential for clear articulation.
    • Further clinical studies are warranted to validate the efficacy of these proposed speech aids in prosthodontic patients.
