The document discusses different classifications for removable partial dentures, including the popular Kennedy classification system. The Kennedy system categorizes partially edentulous areas into four classes based on the location of edentulous regions in relation to remaining natural teeth. Class I involves bilateral edentulous areas behind the natural teeth. Class II is a unilateral area in the back. Class III is a unilateral area with teeth on both sides. Class IV is a single bilateral area in front of remaining teeth. The document also notes more recent classifications are based on diagnostic criteria rather than location alone.
