It should let instantaneous visualization of
the kind of partially edentulous arch being
considered.
It should let instant difference between the
tooth borne and tooth tissues supported
RPD.
It should be collectively adequate.

 Tooth and Mucosa Borne
 When usage in conjunction with a support
classification, it assistances to give a clear classification
considerate about the sort of denture under
consideration during a conversation on partial
dentures.
 Worldwide suitable classification Planned by Edward
Kennedy in 1923
 Kennedy classification is founded on the connection of
the burdens to the usual teeth.
 The Most Subsequent edentulous area determines
the class.
 If a third molar is missing and not to be substituted
it is not considered in decisive the class.
 The size of the modification is not significant.
 upsKennedys classification has four chief
with amendments excluding for class IV
Class I: Two-sided free end
edentulous spaces posterior
to the normal teeth.
Class II: One-sided free
end edentulous space
posterior to the normal teeth.
Class III: Abounded one-
sided edentulous space
having natural teeth at each
end.
Class IV: Thrived
edentulous space
anterior to the natural teeth.
Examples Of Modifications:
An additional edentulous area in Class I
would be designated as Class I modification 1
If two further edentulous
existing it could be designate
areas are
as Class I
modification 2
A one-sided saddle with one extra
edentulous area is Class II modification 1
A unilateral bounded edentulous area with three
additional edentulous areas is class III
modification 3
 Permits visualization of partly edentulous arch
 Distinguishes between tooth supported and tooth tissue
maintained Type of design can be unquestionable is
generally accepted
 Aids in discussing identifying and planning the design
 First classification to be recognised by the
dental line of work


He classified partial dentures than edentulous
spaces
Four types
1. Diagonal: 2 deposits slantwise opposite another
2. Diametric: 2 retainers utterly opposite one
another.
3. Unilateral: 2 or more direct deposits on same
side.
4. Multilateral: 3 direct deposits on either side.
 He emphasized the significance of provision for partial
dentures.
 A- Anterior refurbishments where there were burden
areas forward to the bicuspids.
 P- Posterior restorations where there were saddle areas
posterior to the canines.

Class I: Bounded
saddle (Tooth
supported).
 Class II: Free end saddle
(Mucosa supported).
{
 Class III: Bounded saddle
(More than 3 tooth missing).
Example: If all subsequent teeth from pooches
till molars are missing with lateral incisors
then the classification is AI P III.
 Class I: Variation I:
a. Posterior missing, Forward all teeth present.
b. Posterior missing, some anterior teeth
missing.
 Variation II
a. Anterior missing, All posteriors present.
b. Anterior missing, some posteriors missing.




Class II: Division I has variation 1 and 2.
Division II has variation 1 and 2
This classification is tooth tissue
bearing. Class III is edentulous state.
A- Anterior space.
B- Bound Posterior Space.


 C-Cantilever condition or a posterior free end
saddle.
Class I: Mucosa borne.
Class II: Tooth borne


 Class III: Mixture of mucosa borne and tissue
borne.


RULE 1: classification should follow rather
than herald any removals of teeth hat
might alter the unique classification.
RULE 2: If a third molar is missing and not to be
replaced it is not considered in the classification


RULE 3: If a third molar is present and is to be
used as an abutment, it is considered in the
classification
RULE 4: If a second molar is missing and is not to
be replaced, it is not considered in the
classification
 RULE 5: The classification is always posteriorly determined
by the most edentulous area or areas



RULE 6: Edentulous areas other than those decisive the
classification are mentioned to as modifications and are
designated by their number.
RULE 7:The extent of modification is not measured, only
the number of added edentulous areas.
RULE 8: There can be no modification areas in class IV
arches (another edentulous area lying posterior to the
single bilateral area crossing the midline would
determine the classification.)
Applegate added two more classes to
Kennedys existing classification
Class V: This is an edentulous area restricted
anteriorly and posteriorly by natural teeth, in
which the forward abutment is not appropriate for
support.
Class VI: This is an edentulous state in which the
abutment tooth is talented of total provision.(As
in young patients)
