Basic Prosthodontic Terminology
Support is the foundation on which a dental prosthesis rests or to hold up and serve as foundation.
Stability is the quality of a prosthesis to be firm, stable or constant and to resist displacement by functional, horizontal or rotational stresses.
Retention is the quality inherent in the denture that resists the vertical forces of dislodgement.
Prosthesis is a proper term for denture, obturator, a fixed partial denture or crown.
Removable Partial Denture is a dental prosthesis that replaces some teeth in a partially dentate arch and can be removed and replaced at will.
Fixed Partial Denture is a dental prosthesis that replaces some teeth in a partially dentate arch and can not be removed at will by the patient.
Complete Denture is a dental prosthesis that replaces all of the natural dentition and associated structures of the maxilla or mandible.
Interim Denture (Provisional Denture) is a dental prosthesis used for a short time for reasons of esthetics, mastication, occlusal 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.
Appliance is a term applied to devices, such as splints, orthodontic and space maintainers, worn by the patient in the course of treatment.
Abutment is a tooth, portion of a tooth or a portion of an implant that serves to support and/or retain a prosthesis.
Denture Base is the part of a denture that rests on the residual bone covered by soft tissue and to which the teeth are attached.
Residual Ridge (Edentulous Ridge) is the residual bone with its soft tissue that covers the underlying area of the denture base.
Basal Seat (Denture Foundation Area) is the oral tissues and structures of the residual ridge supporting a denture base.
