  • 1. Indications ofAlternative RPD designs
    Amin Amusallamah
  • 2. Acrylic r esin RPDs
    Attachments for RPDs
    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.
    The wax - up showing replacement of teeth nos. 23 – 26 on 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.

    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.
  • 7. Cont…
    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.
