2. FIXED PARTIAL DENTURES series 1/2
INTRODUCTION and BASICS

3. Partial Dentures
Replacement of a few teeth
• Removable (RPD)
• Fixed (FPD/Bridges)

4. Crown
• Fixed extra-coronal artificial
restoration that covers the coronal
portion of natural tooth.

5. (Dental) Implant
• Artificial tooth root placed into jaw
to hold a replacement tooth, bridge
or denture

6. Veneers
• Thin layer prepared over facial
surfaces of the anterior teeth for
aesthetics

7. Inlay | Onlay
• Inlay: An intra-coronal
restoration (deep decayed
tooth)
• Onlay: Intra-coronal
restoration, resorting
missing cusps.

8. Parts of FPD/Bridge
• Retainer: crown that is used as
a parted of FPD for retention
and support from abutment.
• Pontic: artificial tooth
replacement.
• Connector: connection between
pontic and retainer.
Abutment: any tooth, root or
implant which gives retention and
support to FPD.

9. Retainers
• Major retainer: which cover the entire
occluding surface. (Full/partial veneer
crowns)
• Minor retainer: small extensions cemented
onto the tooth. (inlay/onlay)

10. Retainers Classification
BASEDONTOOTH COVERAGE
• Full veneers crown: that covers all five surfaces of crown.
• Partial veneer crowns: don’t cover all surfaces.
• Conservative retainers: require minimal tooth reduction (acid etching)
• Telescopic retainers: when path of insertion doesn’t conside with long
axis of abdutments. FPD is cemented in copings.

11. Retainers Classification
BASEDON MATERIAL USED
• All metal retainers: can be partial/full. Require minimal reduction.
• Ceramic fused to metal retainers: require more reduction.
• All ceramic retainers: can be partial/full. Require maximum reduction.
• All acrylic retainers: indicated for temporary FPD.

12. Pontic
• The part of FPD that replaces the
missing teeth.

13. Pontic Classification
ACCORDINGTO (with) MUCOSAL CONTACT
• Ridge lap pontic: resembles to natural tooth. Adapts closely to the
ridge.
• Modified ridge lap pontic: tissue contact on buccal surface of ridge.
• Saddle pontic: overlaps the ridge buccaly and lingually.
• Ovate pontic: for defective/incompletely healed ridges.
• Spheroidal pontic: contact only on ridge crest.
• Bullet/Conical/Heart shaped pontic: contacts the tissue in a single
point without any pressure.

14. Pontic Classification
ACCORDINGTO (with) MUCOSAL CONTACT

15. Pontic Classification
ACCORDINGTO (without) MUCOSALCONTACT
• Bullet shaped pontic: same as bullet shaped but without mucosal
contact.
• Hygienic/Sanitary pontic: don’t make any contact with ridge. Easy
to maintain but un-aesthetic.

16. Pontic Classification
ACCORDINGTO MATERIAL USED
• Metal and ceramic veneered pointic
• Metal and resin veneered pontic
• All metal pontic
• All ceramic pontic

17. Connector
• Portion of FPD that unites pontics
and retainers.

18. types of Connector
• Rigid connector: when entire load on
pontics to be transferred directly to
the abutments. Conventional
type/Indicated for short span bridges.

19. types of Connector
• Non-rigid connector: indicated when single path of insertion can’t be
achieved due to unparallel abutments.
– Tenon Mortise connector: it got male (Tenon) and female(Mortise) components
or dovetail.
– Split pontic connector: connector incorporated within the pontic. Pontic is split
into mesial and distal segment which are attached to their respective retainers.
– Cross-pin/Wing connector: similar to the split connector. Indicated on tilted
abutments.
– Loop connector: lingual loops is given to connect the retainer/abutment; when
existing diastema to be maintained.
– Locking rod connector: connector occurs in pontic space.

20. types of Connector
NON-RIGID

21. Types of Fixed Partial Denture
• Conventional FPD (Fixed-Fixed FPD):
– most commonly used. Support taken form
abutments on both sides of edentulous space.
• Cantilever FPD:
– when support taken form one side of
edentulous space.

22. Types of Fixed Partial Denture
• Spring Cantilever FPD:
– Exclusively designed for replacement of
maxillary central incisor. Support is to be
obtained form posterior abutment.
• Fixed-movable partial denture:
– RPD having one (or more) non-rigid connector.

23. Types of Fixed Partial Denture
• Fixed-removable partial denture:
– One part is fixed while other part is kept
removable. Indication: maxillary/mandibular
defects, long span bridge.
