Study Notes
Dental Classification Systems
- Dental classifications are based on the location and support of missing teeth
- Different classifications exist to clarify issues in prosthetic treatment of partial edentulism
- Classification types include Cummer (1942), Wild (1933-1943), Martin, Beckett, Costa, and Kennedy (1923+)
- Kennedy's system divides partial edentulism into 4 classes:
- Class I: bilateral posterior edentulism
- Class II: unilateral posterior edentulism
- Class III: bilateral intercalary edentulism
- Class IV: anterior edentulism
Kennedy Classification (K-A)
-
K-A classification has 6 fundamental classes:
- Class I: distal bilateral edentulism
- Class II: distal unilateral edentulism
- Class III: bilateral edentulism (with canines)
- Class IV: anterior impacted edentulism
- Class V: impacted bilateral edentulism (loss of at least one canine)
- Class VI: unilateral impacted edentulism
-
Modifications to the classification are identified numerically, correlating to the number of additional missing teeth segments.
-
Missing teeth themselves aren't used in determining the class.
-
Class I can be further categorized:
- Class I mod1: distal bilateral edentulism, complicated by impacted edentulism at the residual arch
-
Class II can be further categorized:
- Class II mod1: unilateral distal edentulism, complicated by impacted edentulism on the opposite side of the arch
Additional Considerations in K-A Classification
- Extractions should be considered; future extractions may alter the classification
- The most posterior edentulous segment determines the primary classification.
- The number of modifications to a class (impacted teeth) is defined by the number of edentulous segments rather than by the number of missing teeth.
