2. It is a fixed restoration
which replaces one or more
missing teeth.
It is cemented to the
natural teeth, roots or fixed
with a screw to an implant.
It has 3 components:
- Pontic
- Connectors
- Retainer
3. Retainer
it is an fixed restoration, usually in the
form of crown, which is cemented to the
prepared abutment tooth, to provide
stabilization for the Fixed partial denture
(FPD).
Retainer
4. According to retention,
retainers are classified as:
- Extra coronal retainers
- Intra coronal retainers
- Intra radicular retainers
5. Full coverage:
* Full metal crown
* Metal ceramic crown
* Jacket crown
* Telescopic crown**
Partial coverage:
* ¾ crown
* Reversed ¾ crown
* ½ crown
* Pin-ledge *Telescopic crown: it is referred to as a double crown. It
is consists of two parts: fixed primary (inner telescope
* Modified type crown) and removable secondary (outer telescope crown
interlocking on top of the fixed.
6. Inlay { M.O.D inlay* is the most commonly used}
Onlay
By post
By post and core
Pin-ledge
Combination of the above
*M.O.D inlay: it is a fixed restoration restores the damaged occlusal
and proximal (mesial and distal) surfaces of the tooth without
covering the cusps.
7. Abutment tooth
it is a natural tooth or an implant used
to support and retain the FPD at one or
both terminals.
Abutment
8. According to its position in relation to
edentulous area, it is classified as:
- Primary abutment: that provides the bridge
with prime means of support.
- Secondary abutment: that supports the primary
abutment in addition to that provides the
support to the bridge.
- Pier abutment: is an isolated or intermediate
abutment where the anterior and posterior
adjacent teeth to it are missing.
- Distal abutment: that is situated distal to the
edentulous area or the last abutment distally.
9. According to its nature, it is classified as:
- natural tooth
* full tooth (crown and root)
* remaining root (post and core)
- implant
10. Pontic
is it an artificial coronal part of the
meaning tooth to be replaced.
11. According to the material used in its construction:
- Metallic
- Combination between metal and resin
- Combination between metal and ceramic
- All ceramic
- All resin
According to its interface relationship between the
residual alveolar ridge and the gingiva:
- Lap
- Modified Lap
- Hygienic
- Saddle type
12. Connector (or joint)
it is that part of FPD that joins its
components with each other, retainer with
pontic, retainer with retainer or pontic to
pontic.
13. they are classified into:
1. Rigid connector:
- cast connector
- soldered connector
* pre- soldered
* post-soldered
2. Semi-rigid connector:
- interlocks custom made
- precision attachment
3. Loop or a spring type
