5. • Interim denture
• Enhance the esthetics, stabilization and/or function for a
limited time
• Later replaced by definitive prosthesis
• Transitional denture
• An interim denture in which artificial teeth are added as
natural teeth lost
• Treatment denture
• Used for the purpose of treatment or conditioning of
tissue
• Post surgery
TEMPORARYREMOVABLEPARTIALDENTURES
8. MANDIBULAR MAJOR CONNECTORS:
• Lingual Bar (All situations where min 8mm space coverage is req)
• Sub-lingual bar (Distance of floor or mouth to gingival margin is < 6mm)
9. • Continuous Bar (Wide diastema)
• Labial Bar (Severe lingual inclinations)
10. MAXILLARY MAJOR CONNECTORS:
• Single palatal strap (Bilateral short span edentulous spaces)
• Single palatal bar (Interim partial dentures)
• Anterior posterior palatal strap (All Kennedy situations, Multiple saddle areas)
11. • Anterior posterior palatal bars (Kennedy Class II and IV)
• Complete Palatal plate (Distal extension conditions, Cleft palate, Heavy occlusal forces)
• U shaped (Inoperable tori, Least suitable design)
12. MINORCONNECTORS
• Functions
• Transfers functional stresses to abutment teeth
• Maintain a path of insertion
Base
Other Components
(Clasps, rests,
Indirect retainers)
13. RESTSANDRESTSEAT
• Provides vertical support
• Transfers the forces along the long axis of teeth
• Positional maintenance
• Rest Seat:
• The prepared surface on the abutment teeth
to receive the rest
15. DIRECTRETAINERS
Component of RPD that functions to retain
and prevent the dislodgement of the
denture
Intracoronal
Precision
Semi
precision
Extracoronal
Clasps
Prefabricated
attachments
30. 1.How the RPD is supported?
•Tooth Supported
• Kennedy class 3 and 4
• Tooth – Tissue Supported
• Kennedy Class 1 and 2
• Away from abutment Tissue Support
• Adjacent to edentulous area Tooth
support
• Quality of Ridge and accuracy of
impression is the key
31. 2. Connecting the tooth and tissue
support units
•Major Connector – Rigid for
proper distribution of load
•Minor connector
•SUPPORT
32. 3. How the RPD is to be retained
• Natural Sources
• Frictional resistance
• Interfacial surface tension
• Palatal vault
• Occlusion
• Clasp assembly (avoiding torqueing forces)
• Splinting
• RETENTION
33. 4.Connecting the Retention units to
the supporting units
Indirect Retainers - STABILIZATION
5.Outlining and joining the
edentulous area to already
established design
