Question: 1 / 400

Which Kennedy Class features a unilateral distal extension?

Class I

Class II

Kennedy Class II is characterized by a unilateral distal extension in a partial denture. This means there is a tooth-supported segment at the front of the arch, with the back end relying on the soft tissue beyond the last remaining natural tooth for support. In this classification, the missing teeth are on one side of the arch, causing the need for a denture to extend to the distal area of that side, which is why it is termed a "unilateral distal extension."

Understanding the Kennedy classification is crucial in dental hygiene and prosthodontics as it helps in planning and managing the treatment for patients requiring partial dentures. The other classes, such as Class I and Class III, deal with different arrangements and types of edentulous areas, while Class IV involves a single anterior space crossed by the midline, lacking the unilateral aspect of Class II.
