Kennedy's classification system for removable partial dentures is a widely accepted and comprehensive classification system for prosthodontic technicians. It categorizes partial dentures based on the type of tissue they are made of, the shape of the prosthesis, and the retention mechanism.
The classification system is divided into two main categories: removable partial dentures with acrylic resin base and removable partial dentures with metal frameworks.
Removable partial dentures with acrylic resin base
These dentures are made of acrylic resin, a lightweight and flexible material that is highly biocompatible.
They are typically cast in a dental laboratory and bonded to the patient's natural teeth using a special resin.
Acrylic resin dentures provide a natural-looking and comfortable fit and are suitable for patients with allergies or sensitivities to other materials.
Removable partial dentures with metal frameworks
These dentures are made of a metal framework, such as stainless steel or cobalt-based alloy.
They are typically custom-fabricated to fit the patient's exact bite and anatomy.
Metal frameworks provide greater stability and retention compared to acrylic resin dentures.
Kennedy's classification system also provides additional categories for removable partial dentures based on the type of tissue they are made of and the retention mechanism. For example:
Acrylic resin base with acrylic clasps
Acrylic resin base with metal frameworks
Cobalt-based alloy framework
Metal framework with acrylic clasps
Metal framework with rubber liners
The classification system is widely used in dental schools, clinics, and prosthodontic laboratories worldwide. It ensures that patients receive removable partial dentures that are properly fitted and meet the individual's oral health needs
