Study Notes
Kennedy Classification
- Class 1: Bilateral distal extension with edentulous areas located posterior to natural teeth.
- Class 2: Unilateral distal extension with an edentulous area located posterior to remaining natural teeth.
- Class 3: Unilateral bounded edentulous area with natural teeth both anterior and posterior to it; does not cross the midline.
- Class 4: Bounded edentulous area that crosses the midline; a single bilateral area located anterior to remaining natural teeth.
Overview of Applegate's Rules for Applying the Kennedy Classification
- No specific details provided; further exploration of rules required.
Applegate-Kennedy Classifications
- Class 5: Bounded edentulous area with natural teeth anteriorly and posteriorly, but the anterior abutment is unsuitable for support; similar to Class 3 but without usable anterior support.
- Class 6: Edentulous area supported entirely by adjacent teeth, requiring minimal tissue support, distinguishing it from typical tooth and tissue-supported dentures.
Modification Spaces
- Lone-standing, single-rooted abutments should be splinted to the nearest tooth with a fixed partial denture when binding a modification space.
- Presence of two modification spaces complicates RPD design; considering a 3-unit fixed bridge may help eliminate one space.
Fixed Restorations and Modification Spaces
- Consider fixed restorations for modification spaces instead of including them in the removable partial denture, particularly with isolated abutment teeth.
- Evaluate the cost against the benefits of splinting.
- Designs with multiple bounded areas replaced by RPDs alongside isolated abutments and distal extensions often yield poor success rates.
- Prioritize biomechanical concerns and the health of remaining teeth over economic factors during decision-making.
Impact of Replacing Lateral Incisor Teeth with RPD
- Missing maxillary lateral incisors and posterior teeth is common.
- Replacement of lateral incisors with RPDs typically results in frequent breakage of the denture teeth.
Considerations for 3-Unit Fixed Bridges
- Specific examples needed to illustrate bridges that can help eliminate modifications.
Design Considerations for RPD
- In cases with bilateral edentulous spaces, retain the modification instead of opting for a bridge; RPD design is easier in bilateral cases compared to unilateral situations.
