1. Materials that are fl exible and intended to fit into tooth and soft - tissue undercuts.
2. Used after an immediate extraction in which a patient requires stabilization and function during the healing phase of therapy.
3. The resin removable partial denture also is designed to restore appearance until a defi nitive prosthesis can be fabricated

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.

1. Intracoronal attachments:• Intracoronal attachments can help obtain
esthetic results when used in lieu of traditional.

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. Overdenture attachments• They are used to treat partially edentulous
patients according to 3 general categories: posterior edentulous areas, anterior edentulous areas, and interim prostheses.

• Few remaining natural teeth for a conventional RPD
• Periodontally compromised natural teeth.
• Remaining natural teeth in poor position to support a conventional RPD.
• Excessive alveolar bone loss either through traumatic injury or surgical intervention.

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 extracoronal clasp - retained removable partial denture.
