1. REMOVABLE PARTIAL
DENTURES

2. Need for classification ?
1. To communicate the condition of the oral cavity.
2. To create an order from innumerable possible combination of teeth present and the
edentulous spaces.
3. To contribute to learning the fundamentals of design and to anticipate the difficulties
that commonly occur for that particular design.
4. To design a denture according to the occlusal load usually expected for a particular
group.
5. To formulate a good treatment plan.

3. REQUIREMENTS
1. Should allow visualization of the type of partially edentulous arches
being considered.
2. Should permit differentiation between tooth-supported and tooth–
tissue-supported partial dentures.
3. Serve as a guide to the type of design to be used.
4. The classification should be simple and universally acceptable.

4. KENNEDY’S CLASSIFICATION
• Edward Kennedy in 1923
• is based on the relationship of the edentulous spaces to the
abutment ( ? ) teeth.
• 4 classes ( class I – most common ; class IV – least ) – based
on occurrence.
• Class I II IV – tooth-tissue supported & Class III – tooth
supported – based on design principle.
• Edentulous areas other than those that determine the basic
classes were designated as Modification spaces.

5. CLASS I
bilateral edentulous area situated posterior to natural teeth

6. CLASS II
unilateral edentulous area situated posterior to natural teeth

7. CLASS III
edentulous space bounded on both side by natural teeth

8. CLASS IV
A single, but bilateral edentulous area located anterior to the
natural teeth

9. Kennedy Classification Summary:
•Class I – posterior, bilateral free-end saddles
•Class II – posterior, unilateral free-end saddle
•Class III – posterior, unilateral bounded saddle
•Class IV – anterior bounded saddle
•Class I, II and III can have modifications.

10. APPLEGATE’S RULES
RULE 1 RULE 2
The classification should follow, not precede extractions If a 3rd molar is missing and not to be
replaced, it is not considered in the
classification.

11. RULE 3 RULE 4 RULE
5
If 3rd molar is present and
not to be used as an
abutment, it is not considered
in the classification
If 2nd molar is missing and
not to be replaced, it is not
considered in the
classification
The most posterior area
always determines the
classification

12. RULE 6 RULE 7 RULE 8
Edentulous areas other than
those determining the
classification are referred to
as modifications and
designated by their Number
The extent of the modifications
is not considered, only the No.
of additional edentulous
areas.
There are no modification in Class IV.

13. HOUSE CLASSIFICATION OF
MENTAL ATTITUDE
( DIAGNOSIS AND TREATMENT PLANNING IN PATIENT WITH CD )

14. Dr M.M. House (1950) classified patients as
• Class1 - Philosophical
• Class2 - Exacting
• Class3 - Hysterical
• Class4 - Indifferent
