design of fpd if different different missing teeth position

1. FPD DESIGN by dr vikram

2. Fixed Partial Denture Configurations
 A fixed partial denture can be classified as either simple or complex,
depending on the number of teeth to be replaced and the position of the
edentulous space in the arch.
 The classic simple fixed partial denture is one or two tooth are missing
 Complex fixed partial denture is two or more than two tooth are missing
included pier abutment.
 Simple Complex
One mising two missing two more than two

3. Missing central
In mandible
Implant
Resin-bonded retainers
Removable
FPD ( most chances of pulp exposure during prepration)
In maxilla
Resin-bonded retainers might be used if the
patient is very young and if the abutments are
healthy teeth that have never been restored
&
FPD supporting central and lateral incisor (if
any carious or need restoration )

4. Missing lateral
the removal of all of the mandibular
incisors then would be a canine-to
caninefixed partial denture
Maxila
if the pontic will not contact in centric
relation or excursions, a single-
abutment cantilever fixed partial
denture could be used.
In mandible
Ideally Implant
.If inadequate space is available.

5. Missing 1st Premolar
In maxilla and mandible
Implant
cantilever prosthesis using
second premolar and first
molar

6. Missing 2nd Premolar
In Maxilla
Fpd with abutment first
premolar and first molar
In mandible
Resin-bonded retainers can be used if
the first premolar is large and if the abutments
are caries-free or only minimally affected by
caries.

7. Missing molar
In Maxilla
Full crown or ¾ crown on
the premolar
and ⅞ crown on the molar
In mandible
tilted molar may require
orthodontic uprighting, a proximal half crown,
or a telescope crown

8. Missing 2nd Molar
In maxilla and mandible
Restoration with a
cantilevered fixed partial
denture is not
recommended due to the
excessive tensile
stresses placed on the
premolar abutment and
the retainer.

9. Complex Fixed Partial Dentures (One Tooth)
canine missing
In Maxilla
Implant (choice )
Using the two premolars and the lateral
incisor as abutments is not desirable
because it places too heavy a burden on
the smaller single abutment, the lateral
incisor
In Mandible
Implant (choice),
remove the lateral incisor and use both central
incisors as abutments if a fixed partial denture
is used.

10. Simple Fixed Partial Dentures (Two Teeth)
Missing cental and lateral
In Maxilla
pin-modified partial
coverage crowns
could be used.
In mandible
If there has been any bone
loss around the incisors, or if they are
malpositioned, remove them. FPD canine to
canine

11. Missing both premolar
In Maxilla and mandible
FPD using abutment canine
and molar

12. Missig 2nd Premolar and 1stmolar
In mandible
If the premolar root is short
or thin, or if the clinical crown is very small,
the canine should be included as a secondary
abutment.
In maxilla
bridge on the premolar and on the molar

13. Missing both molars
In Maxilla and mandible
fixed partial denture
cannot be used in this situation because there
is no distal abutment and a cantilever would
place excessive force on the premolars
Implant

14. Complex Fixed Partial Dentures (Two Teeth)
Missing mandibular Central and lateral
six-unit fixed partial denture with
retainers on the canines.(if periodontaly weak
incisor)
Resin-bonded retainers (only if
prospective abutments are large and ideally
located)

15. Missing both Maxillary central
Incisor
When the bony support for
the lateral incisors is poor, it is often best to
extract them and lengthen the fixed partial
denture span. If the lateral incisors have long
roots and crowns, they alone can be used as
abutments.

16. Missing Lateral and Canine
In Maxilla
Span length, abutment
position, and root configuration can make
the use of four abutments desirable
In Mandible
The short edentulous span
and the direction of forces on the mandibular
canine do not require the use of the second
premolar as an abutment.

17. Missing Canine and 1st
premolar In Maxilla and mandible
Group function should be
used.
FPD involve incisors and second
premolar and ⅞ crown on the molar or
full crown

18. Complex Fixed Partial Dentures (More Than Two Teeth)
Missing Both maxillary central incisors and
one lateral incisor
fixed partial denture lengthened to include
the first premolars. Inclusion of first
premolars as abutments will depend on
span length and curvature.

19. Missing all incisor
In maxilla
To counteract the lever arm
double abutments are used.
If the anterior curvature is slight and/or the
canines are exceptionally large, the premolars
may be omitted as abutments.
In mandible
There is no need to use double abutments on the mandibular canine-
tocanine fixed partial denture because the forces
are less destructive

20. Missing: Maxillary first and second
premolars and first molar
In maxilla
This fixed partial denture can
be made only if the clinical crowns of the
abutments are long and perfectly aligned
In mandible
A fixed partial denture should not be used in this situation because the interarch
space is usually insufficient and occlusal force will be directed against the inner
curvature of the occlusal plane, with resultant lifting forces on the retainers

21. Complex Fixed Partial Dentures (Pier Abutment)
Missing central incisor and opposite-side lateral incisor
In Maxilla
keyway-distal aspect of the
central incisor
key - mesial aspect of the lateral
incisor pontic.
If the central incisor is
malpositioned or rotated, its
extraction will simplify the
restoration and improve its
prognosis.
In mandible
a completely rigid fixed partial denture is used in this situation
cause of short span length and small teeth.

22. Missing Both Maxillary lateral incisors and
one central incisor
There should be a nonrigid
connector between the distal aspect of the
central incisor retainer and the mesial aspect
of the adjacent lateral incisor pontic. If the
central incisor is malposed or periodontally
compromised, it should be extracte

23. Missing lateral incisor and first
premolar
In Maxilla and mandible
A nonrigid connector should
be placed between the canine and first
premolar

24. Missing canine and second premolar
In Maxilla and Mandible
A nonrigid connector should
be placed between the first
premolar retainer
and second premolar pontic.

25. Missing: All incisors and one first
premolar
In maxilla and mandible
Both canines, the opposite-side
first premolar, and the second premolar
A nonrigid connector should
be placed at the distal aspect of the
retainer on the canine pier abutment.

26. Missing lateral incisor and first
and second premolars
In maxilla and mandible
Canine-guided posterior
disocclusion.The short lever
arm created by
the lateral incisor cantilever
should be
adequately offset by the long
span from first
molar to canine.

27. Missing first premolar and first
molar
In maxilla and mandible
A nonrigid connector should
be placed on the distal aspect of the second
premolar retainer.

28. Missing: Maxillary central incisor, lateral
incisor, and first and second premolars on one
side
This would be an extremely
difficult fixed partial denture in
either the maxillary or mandibular
arch.The span lengths of both
edentulous spaces are too great
for nonrigid connectors with either
pontic. Implant-supported fpd or a
removable partial denture are
preferable
