Components of Removable Partial Denture

Retention in Removable Partial Denture

• Retention in a removable partial denture refers to the ability of the prosthesis to resist dislodgement from the underlying tissues.

Support in Removable Partial Denture

• Support in a removable partial denture is derived from the teeth and the surrounding tissues.
• The primary component responsible for providing support is the abutment teeth.

Resistance to Vertical Forces

• The component that helps to resist vertical forces of mastication in a removable partial denture is the occlusal rest.

Maximizing Support

• Support can be maximized in a removable partial denture by distributing the occlusal load evenly among the abutment teeth.

Stability in Removable Partial Denture

• Stability in a removable partial denture refers to the ability of the prosthesis to resist movement or rotation during function.
• The primary factor contributing to the stability of a denture is the proper distribution of load among the abutment teeth.

Components of Removable Partial Denture

• The component that directly retains the prosthesis in position is the clasp.
• The major connector provides a pathway for the other components of the removable partial denture and helps to distribute the forces evenly.
• An indirect retainer is a component that is located on the opposite side of the fulcrum line and helps to resist the movement of the prosthesis.

Function of Rests

• The rest contributes to a partial denture by providing a point of support and helping to resist vertical forces.

Factors Affecting Retention

• The primary factor affecting retention in a removable partial denture is the accuracy of fit.

Additional Facts

• The clasp is responsible for directly retaining the prosthesis in position.
• The primary function of direct retainers in a removable partial denture is to provide retention and resist dislodgement.
• The component that provides vertical support on a tooth surface is the rest.
• The major connector provides a pathway for the other components of the removable partial denture and helps to distribute the forces evenly.
• Indirect retainers are located on the opposite side of the fulcrum line in a partial denture framework.
• The primary factor contributing to the stability of a removable partial denture is the proper distribution of load among the abutment teeth.
• Support in a removable partial denture is derived from the teeth and the surrounding tissues.
