Class III removable partial dentures are designed to be worn where there are teeth with missing teeth around them both front and back. While other removable partial dentures fit around the teeth and rest on the gums, removable partial dentures III’s fit strictly on the teeth. This gives them much greater stability than the others.
If both central incisors are missing a class IV removable partial dentures are required. In this case, teeth are missing from one area of the mouth.
