Study Notes
Classification System in Prosthodontic Treatment
- Aids in prosthodontic treatment by categorizing edentulous location, abutment condition, occlusal characteristics, and residual ridge characteristics.
Requirements for Partially Edentulous Arch Classification
- Universally acceptable
- Allows immediate visualization of the arch type
- Differentiates between tooth-supported and tissue-supported removable partial dentures
Kennedy Classification
- Most widely accepted classification of partially edentulous arches
- Divides arches into four basic classes
- Edentulous areas other than those determining the basic classes are designated as modification spaces
Kennedy Classification Classes
- Class I: Bilateral edentulous areas located posterior to natural teeth
- Class II: Unilateral edentulous area located posterior to remaining natural teeth
- Class III: Unilateral edentulous area with natural teeth remaining both anterior and posterior to it
- Class IV: Single, bilateral edentulous area (crossing the midline)

- Eight rules governing application of the Kennedy method
- Rule 1: Classification should follow rather than precede extractions that might alter the original classification
