Full dentures serve to replace natural teeth in the case of complete loss of teeth in one or both jaws. The full denture especially serves to restore the chewing function, phonetics and aesthetics of natural teeth, whereby tissue bearing or touching the dentures may not be damaged. In contrast to partial dentures, full dentures no longer enable the participation of teeth for prosthetic attachment. The full dentures may not be lifted by mucous membrane movement, mimical and chewing muscles.
