Study Notes
Kennedy Classification Requirements
- Immediate visualization of partially edentulous arch types.
- Differentiation between tooth-supported and tooth-tissue supported removable partial dentures.
- Universally accepted system.
Kennedy Classification Overview
- Based on frequency of occurrence in partially edentulous arches.
Kennedy Classes
- Class 1: Bilateral edentulous areas posterior to remaining natural teeth.
- Class 2: One distal extension area located posterior to the remaining natural teeth.
- Class 3: Edentulous area with natural teeth remaining both anterior and posterior.
- Class 4: Single, bilateral edentulous area located anterior to remaining natural teeth.
Applegate's Rules
- Set of rules governing the application of Kennedy classification system.
Rule Highlights
- Rule 1: Edentulous areas not determining classification termed 'modification spaces'.
- Rule 2: Modification space extent not considered; only the number of additional edentulous areas matters.
- Rule 3: Classification follows any extraction of teeth, not precedes.
- Rule 4: The most posterior edentulous area determines the classification.
- Rule 5: Missing molars considered only if to be replaced; second/third molars not included if not being replaced.
- Rule 5: Third molars typically not replaced with removable partial dentures (RPD). If present as abutments, they are considered in classification.
- Rule 6: Class IV arches do not have modification spaces; any areas posterior to the bilateral area help determine classification.
Edentulous Areas
- A Class IV always crosses the midline and lacks modification spaces.
- Edentulous areas may not need to be the same length.
- Edentulous areas extending to the distal aspect of the arch are called distal extension areas.
- Additional missing teeth anterior to extension areas are termed modification spaces.
Specific Class Characteristics
- Class II characterized by one distal extension area.
- Class III characterized by no distal extension areas.
- Class IV defined by one modification space that crosses the midline.
- Maxillary Class IV associated with trauma; Mandibular Class IV related to periodontal disease.
