Study Notes
Prosthetics and Prosthodontics
- Prosthetics is the art and science of replacing a missing part of the body with an artificial appliance.
- Prosthodontics is the branch of dentistry that deals with the restoration and maintenance of oral function, comfort, appearance, and health by replacing missing parts of the oral and para-oral structures with artificial substitutes.
Types of Prosthodontics
- Fixed Prosthodontics: includes fixed partial dentures that are cemented to natural teeth or tooth roots.
- Removable Prosthodontics: includes removable partial dentures and complete dentures.
Definitions
- Natural dentition: the teeth in the dental arch.
- Dentulous: a condition in which natural teeth are present in the mouth.
- Edentulous: a condition in which the mouth is without teeth.
- Partially edentulous: a condition in which some natural teeth are lost.
Dentures
- Denture: an artificial substitute for missing natural teeth and adjacent tissues.
- Complete denture: a dental prosthesis that replaces the entire natural dentition and its associated structures.
- Partial denture: a dental prosthesis that replaces one or more but less than all the natural teeth and its associated structures.
Functions of Complete Dentures
- Mastication: to improve chewing ability.
- Speech: to improve speech and phonetics.
- Appearance: to improve aesthetics and esthetics.
- Health of the alveolar bone and temporomandibular joints: to maintain the health of these structures.
Morphology of Complete Dentures
- Denture base: the part of the denture that rests on the foundation tissues and to which teeth are attached.
- Denture surfaces: basal, polished, and occlusal surfaces.
- Denture borders: the margin of the denture base at the junction of the polished surface and the impression surface.
- Denture flanges: vertical extensions of the denture base that extend from the cervical ends of the teeth to the borders of the denture.
Steps of Complete Denture Construction
- Clinical steps:
- History taking and mouth examination
- Preliminary impression
- Final impression
- Recording of jaws relationships and selection of artificial teeth
- Try-in of the waxed-up dentures
- Laboratory steps:
- Casting of the preliminary impression
- Construction of special trays
- Boxing-in and casting of the final impression
- Construction of record blocks
