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
