2. According to the site, FPD is classified as:
- Anterior bridge :
* bilateral
* unilateral
- Posterior bridge
- Complex bridge
3. Anterior FPD:
It extends only between the anterior teeth.
and it could be:
- Unilateral (two or three teeth bridge):
doesn't cross the midline.
- Bilateral (three or four teeth bridge):
involves teeth on both sides.
4. Posterior FPD:
It extends only between the posterior
teeth.
Complex FPD:
It extends at one of its terminals
beyond the canine.
5. According to retention, FPD is classified
as:
- Simple bridge:
* Fixed- Fixed
* Fixed- Supported
* Cantilever
* Spring cantilever
- Compound bridge
6. Simple bridge:
it is one single bridge, and it may be:
1- Fixed- Fixed bridge:
which is fixed at both ends to the abutment
teeth.
2- Fixed- Supported:
which is connected to one of the terminal
abutment teeth by a non-rigid connector to
allow some individual movements of the pontic.
7. Simple bridge:
3- Cantilever bridge:
which is a free-end bridge, where the
pontic is fixed to and derives its support
from one or double retainers at one end only
and the other end is unsupported.
4- Spring cantilever bridge:
which is a cantilever bridge, where the
pontic is at the end of slightly resilient
curved arm deriving its support from an
abutment tooth remote from edentulous
space.
8. Compound bridge:
it is a combination type of
bridge, contains more than one type
of simple bridge.
9. According to material, FPD is classified as:
- Metallic:
* precious alloy
* semi precious alloy
* non precious alloy
- Combined:
* metallic with labial or buccal veneers
* metallic with full veneer
* non metallic with metal reinforcement
or framework (reinforced bridge).
- Non metallic:
*Reinforced bridge: which has a metal reinforced
* all resin, framework embedded within the porcelain or acrylic resin
and remained as a permanent part of the bridge
* all ceramic structure.
10. According to the length of span, it is
classified as:
- short span >> one missing tooth
- medium span >> two missing teeth
- long span >> more than two missing
teeth
11. According to the chronology of span, it is
classified as:
1- Provisional bridge:
to be used for varying period of time.
> Temporary bridge: used temporarily for
the protection of prepared teeth, till the
cementation of bridge is completed.
> immediate bridge: constructed before
extraction of teeth and seated in position
immediately after extraction at the same
visit.
12. 2- Definitive bridge:
to be used over an extended period of
time.
According to the number of teeth missing and
the number of abutments, FPD is classified as:
- Simple > one missing tooth, two abutments
one on each side of the edentulous
area.
- Complex > two missing teeth, two abutments.
- Complex > two missing teeth, more than two
abutments.
- Complex > Pier abutment
13. According to retention, what are the
types of the simple bridge?
Define each type.
What does immediate bridge mean? And does
it use for a long period of time?
Give a schematic view for the classification
of Fixed Partial Denture. (just names)
