Watt et al Classification
He proposed the classification in 1958. It was based on the type of support derived.
• Entirely tooth borne: The entire denture rests on the abutment teeth.
• Entirely tissue borne: The entire denture rests on the soft tissue.
• Partially Tooth borne and partially tissue borne: These dentures rest on both the teeth and the tissues. Generally most of the removable partial dentures come under this category.
