Indirect retainers

By Dr.Swathi Pai on Saturday, January 17, 2009 with 0 comments

  1. These could be rests, minor connectors & proximal plates. They are designed to counteract vertical movement of the denture base away from the tissues (dislodging forces) causes by sticky foods and tissue rebound.

  2. Design:

    1. The greater the distance between the fulcrum line and the indirect retainer (IR), the more effective the IR.

    2. The IR should be at right angles to the fulcrum line.

    3. The IR should be placed in rest seats so as to direct forces through the long axis of the tooth.

    4. Direct retainers must be effective for an IR to function.
