Question: 1 / 400

Which Kennedy Class describes a scenario where the dental prosthesis is supported entirely by existing teeth?

Class I

Class II

Class III

The Kennedy Classification system is used to categorize various types of edentulous spaces in the mouth, specifically for removable partial dentures. Class III describes a scenario where the edentulous area is bounded anteriorly and posteriorly by natural teeth, indicating that the prosthesis is supported entirely by existing teeth.

In this class, the missing teeth are not at the terminal ends of the dental arch; instead, they are situated between teeth that remain in place, allowing the partial denture to rely solely on those remaining teeth for support. This provides a stable foundation for the prosthesis and helps to evenly distribute the occlusal forces across the remaining dentition.

Understanding this classification is key for dental hygiene professionals as it impacts treatment planning, design of the prosthesis, and overall management of the patient's oral health.
