What characterizes a Kennedy Class I RPD?

A Kennedy Class I removable partial denture (RPD) is characterized by bilateral distal extension. This means that there are edentulous areas located posterior to the remaining natural teeth on both sides of the dental arch. This configuration typically requires specific design considerations for support, stability, and retention, as there are no natural teeth remaining in the back of the arch to provide these factors.

Unlike the other classifications, a Kennedy Class I scenario necessitates that the RPD be designed to accommodate the lack of posterior support, relying on the anterior teeth and the soft tissue for support and stabilization. Understanding this classification is crucial for designing effective and functional RPDs, as well as for anticipating the potential challenges presented by the distal extensions, such as the need for more comprehensive support to prevent movement of the prosthesis during function.
