Questions and Answers

What is the function of support in a removable partial denture?

  • Provides firmness and steadiness to the denture
  • Balances the forces acting on different parts of the denture
  • Resists movement of the prosthesis toward the edentulous ridge (correct)
  • Resists movement of the prosthesis away from the edentulous ridge

    • What is the role of retention in a removable partial denture?

  • Provides firmness and steadiness to the denture

    Study Notes

    Functions of Support in Removable Partial Dentures

    • Provides vertical support to distribute occlusal forces evenly across the residual ridge.
    • Prevents movement of the denture during functional activities such as chewing and speaking.
    • Maintains comfort for the patient by reducing tissue stress through appropriate support mechanisms.

    Role of Retention in Removable Partial Dentures

    • Ensures the denture remains securely in place by resisting dislodging forces during function.
    • Achieved through a combination of clasp design, friction, and the physical contours of the supporting teeth and tissues.
    • Important for patient confidence and comfort, allowing for normal function without fear of displacement.

    Stability in Removable Partial Dentures

    • Refers to the ability of the denture to resist horizontal or rotational forces during function.
    • Stability is dependent on proper fit, well-designed connectors, and strategic placement of clasps.
    • Essential for maintaining the position of the denture and preventing discomfort or irritation to oral tissues.

    Reciprocation in Removable Partial Dentures

    • Involves the design elements that counteract the movement of retainers during function.
    • Provides resistance to lateral forces exerted on the supporting teeth from the clasp arms.
    • Crucial for preventing tilting of the abutment tooth and enhancing the overall function and fit of the denture.

    Cross-Tooth Stabilization in Removable Partial Dentures

    • Describes the method of stabilizing a denture by connecting clasps or elements associated with opposing sides of the dental arch.
    • Helps distribute forces evenly across the arch, preventing undue stress on any single tooth or area.
    • Enhances the overall stability and effectiveness of the removable partial denture during function.
