Swing lock RPDs
3. Acrylic resin RPDs
Materials that are fl exible and intended to fit into tooth and soft - tissue undercuts.
Used after an immediate extraction in which a patient requires stabilization and function during the healing phase of therapy.
The resin removable partial denture also is designed to restore appearance until a definitive prosthesis can be fabricated
4. Interim removable partial denture with anterior prosthetic teeth- nos. 9 &10.
Teeth on the cast have been designated for removal prior to fabrication of the immediate transitional RPD.

Interim RPD, occlusal view shows wire clasps for retention on bilateral second premolars.
5. Attachments for RPD s
Intracoronalattachments:
Intracoronal attachments can help obtain esthetic results when used in lieu of traditional.
6. Cont
2. Extracoronal attachments:
They are equally as esthetic as intracoronal attachments, but unlike intracoronal attachments, they have the ability to provide more resilience as a stress.

3. Overdentureattachments
They are used to treat partially edentulous patients according to 3 general categories: posterior edentulous areas, anterior edentulous areas, and interim prostheses.
8. Swing lock RPDs
Few remaining natural teeth for a conventional RPD
Periodontallycompromised natural teeth.
Remaining natural teeth in poor position to support a conventional RPD.
Excessive alveolar bone loss either through traumatic injury or surgical intervention.
9. Cont
The vertical projection arms of the labial arm of a swing - lock removable partial denture can compromise overall esthetic results during speech.
Five mandibular anterior natural teeth provide too few remaining teeth for a conventional extracoronalclasp - retained removable partial denture.
