A complete denture is a full arch of false teeth that rests on top of the gums on the upper or lower part of the mouth. These dentures stay in place with the help of gravity (lower dentures) or a suction grip on the roof of the mouth (upper dentures). A full denture may be may entirely of acrylic, or it can have an inner metal frame for added strength.
A partial denture is a prosthetic that replaces just the teeth that are missing, and it has clasps that help it hook onto the remaining teeth for support.
An implant denture is a denture that has special attachments that snap onto dental implants. The denture looks and feels like a regular denture, but it has extra support and stability from the implants.
