Study Notes
Introduction to Prosthodontics
- Prosthodontics is the branch of dentistry focused on restoring and maintaining oral function, comfort, appearance, and health.
- It involves replacing missing parts of the human body, specifically within the oral cavity.
- A prosthesis is an artificial replacement for a missing part of the human body.
History of False Teeth
- Tooth replacements have existed for centuries.
- The first dentures were created around 700 BC using ivory and bone.
- Silver, gold, and mother-of-pearl were also used.
- Porcelain dentures were introduced in 1774.
- A significant advancement was the discovery of vulcanized rubber.
- Acrylic resin marked a major advancement in prosthodontics.
- Implants are another significant development in tooth replacement.
Definitions
- Dentulous: A person with their natural teeth present.
- Edentulous: A person who has lost their natural teeth; may be partially or completely edentulous depending on the number of missing teeth.
- Prosthetics: The broader concept of replacing missing/lost body parts.
Branches of Prosthodontics
- Fixed prosthodontics: Permanent restorations;
- Removable prosthodontics: Includes:
- Complete denture prosthodontics
- Partial denture prosthodontics
- Implant prosthodontics: Involves use of dental implants
- Maxillofacial prosthetics: Replacements for missing parts of the face and mouth regions.
Types of Prostheses
- Denture: A restoration for one or more missing teeth and related structures; includes partial, complete, fixed, or removable types.
- Partial denture: Restores some tooth function; only replaces a portion of missing teeth, not all.
- Fixed partial denture: Permanently attached restoration to existing teeth or implanted teeth; cannot be removed from the mouth.
- Removable partial denture: A prosthesis for a partially missing tooth arch; removable from the mouth.
- Complete denture: A removable restoration for a completely missing arch; covers the maxilla (upper jaw) and mandible (lower jaw).
Reasons for Tooth Loss
- Traumatic injuries
- Tooth decay (caries)
- Periodontal diseases
- Cysts, malignancies, and tumors
- Radiation therapy for tumors
- Grossly malaligned teeth
- Iatrogenic extraction (extraction by a clinician)
- Congenitally missing teeth
- Failure of teeth to erupt (impacted teeth)
Sequelae of Tooth Loss
- Resorption: The socket of a missing tooth gradually remodels to fit with the edentulous ridge.
- Tilting: Movement of remaining teeth in the arch.
- Drifting: Movement of remaining teeth in the arch.
- Occlusal disharmony: Problems in the chewing surfaces leads to discomfort, pain, and potential TMJ issues.
Treatment Options
- Preservation and prevention
- Post and core/crowns
- Implants
- Fixed partial dentures
- Cast removable partial dentures
- Overdenture (removable restoration of missing teeth supported by implants within the mouth)
- Complete dentures (full arch restorations replacing all or most of the missing teeth.)
- Implant-retained dentures (complete arch restorations supported by implants).
- Maxillofacial prostheses: Replacements for missing areas of the face or mouth.
Masticatory Loads
- Forces produced by natural teeth during mastication are significantly higher than denture wearers' forces.
- Natural teeth can generate forces up to 175 pounds, but typically range between 40 and 50 pounds.
- Denture wearers generate forces in the 22-24 pound range in the molar-bicuspid area.
- Denture-supported forces produce only 10-15% of the forces produced by natural teeth.
