Dentures are also known as dental plate, stay plate, false teeth and gnashers.
Prosthesis is a term used for denture, obturator, fixed partial denture or a crown.
Removable Partial Denture is a prosthesis that replaces some teeth in a partially dentate arch, and can be removed from the mouth and replaced at will.
Fixed Partial Denture is a prosthesis that replaces some teeth in a partially dentate arch, and can not be removed from the mouth nor replaced at will.
Complete Denture is a dental prosthesis that replaces all of the natural dentition and associated structures of the maxilla or mandible. It is entirely supported by tissues – mucous membrane, connective tissues and underlying bone.
Interim Denture / Provisional Denture is a dental prosthesis used for a short time for reasons of esthetics, mastication, occusal support or convenience or for conditioning the patient to accept an artificial substitute for missing natural teeth until a more definite prosthetic dental treatment can be provided.
