Study Notes

Bracing in Partial Dentures

  • Bracing can be provided from the mucosa by covering the lateral slope of the ridge and the lateral slope of the palate.
  • Indirect retainer is achieved through the use of specific components, including:
    • Continuous bar
    • Occlusal rest
    • Cingulum rest
    • Incisal rest
    • Anterior palatal bar
    • Posterior palatal bar

Retention in Partial Dentures

  • Retention in partial dentures relies on mechanical units, including:
    • Direct retainer (for tooth-borne RPD and tooth-tissue borne RPD)
    • Indirect retainer
