Evaluation of mandibular arch width change

G N Gates, J I Nicholls

    The Journal of Prosthetic Dentistry
    |October 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Mandibular arch width changes with forces like biting and opening. Minimizing these forces during dental impressions preserves accurate mandibular width measurements.

    Area of Science:

    • Dentistry
    • Biomechanics
    • Orthodontics

    Background:

    • The mandible's arch width is crucial for dental occlusion and prosthetics.
    • Understanding forces affecting mandibular width is essential for accurate dental procedures.

    Purpose of the Study:

    • To investigate how different forces influence mandibular arch width.
    • To identify methods for minimizing arch width changes during impression making.

    Main Methods:

    • Review of existing literature on mandibular biomechanics.
    • Analysis of forces including maximal opening, protrusion, biting, and retruding forces.

    Main Results:

    • Maximal opening, protrusion, and biting forces decrease mandibular arch width.

    Related Experiment Videos

  • Horizontal retruding forces increase mandibular arch width.
  • Mandibular arch width changes during impression making can be significant.

    • Conclusions:

    • Intrinsic and extrinsic forces dynamically alter mandibular arch width.
    • Preventing protrusive movements and limiting opening to 20 mm minimizes arch width changes during impressions.
    • These findings aid in achieving more accurate dental impressions and treatment outcomes.
