Kennedy Classification Flashcards
What are the requirements for the Kennedy Classification system? (4)
- Allows visualization of the type of arch
- Permits differentiation between the types of support
- Serves as a guide for design
- Is universally accepted
Currently the most widely used classification system for RPD:
Kennedy classification system
Kennedy classification system can be applied to:
All partially edentulous situations
The Kennedy classification system consists of:
Four classes
In the Kennedy classification system, the ____ determines that classification:
Lowest number
Determine the Kennedy Class:
B/L edentulous areas located posterior to the remaining natural teeth:
Kennedy Class I
Determine the Kennedy Class:
A unilateral eventually area located posterior to the remaining natural teeth:
Kennedy Class II
Determine the Kennedy Class:
A unilateral edentulous area with natural teeth remaining both anterior & posterior to it:
Kennedy Class II
Determine the Kennedy Class:
A single, but B/L (crossing the midline) edentulous area located anterior to the remaining natural teeth:
Kennedy Class IV
Edentulous area other than those determining the classification:
Modification space
Eight rules governing the application of the Kennedy Classification system:
Applegate’s rules
Applegate Rule 1 states that classification should:
Follow rather than precede any extractions of teeth that might alter the original classification
Applegate Rule 2 states that if a third molar is missing and is not to be replace:
It is not considered in the classification system
(generally third molars are not replaced with an RPD)
Applegate Rule 3 states that if a third molar is present and is to be used as an abutment:
It is considered in the classification
Applegate Rule 4 states that if a second molar is missing and is not to be replaced:
It is not considered in the classification
(generally if the first molar is present and the second & third molars are missing, the second & third molars are not replaced)
Applegate Rule 5 states that the ______ (or areas) always determines the classification
Most posterior edentulous area
Applegate Rule 6 states that edentulous areas other than those determining the classification are referred to as ______ and are designated by their _____
Modifications; number
Applegate Rule 7 states the ____ of the modification is not considered, only the ____ of additional edentulous areas is considered
Extent; number
Applegate Rule 8 states there can be no ________ in Class ____ arches
Modification areas; Class IV
(Other edentulous areas lying posterior to the single B/L area crossing the midline would instead determine the classification)

Classification type that is based upon the denture type:
Craddock Classification
What are the three Craddock Classifications:
Type 1: Mucosa borne
Type 2: Tooth-borne
Type 3: Mucosa & tooth-borne
