Study Notes

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.
