Study Notes
Introduction to Prosthodontics
- Prosthodontics is a branch of dentistry focused on restoring and maintaining oral health, function, comfort, and appearance in patients.
- Prosthetics are replacements for missing body parts.
- A prosthesis is an artificial replacement of a missing part of the human body.
History of False Teeth
- Replacements for lost teeth have been created for thousands of years.
- The first dentures were made around 700 BC from ivory and bone.
- Materials like silver, gold, and mother-of-pearl were also used.
- Porcelain dentures were introduced in 1774.
- Vulcanized rubber marked a significant advancement.
- Acrylic resin is a major innovation in prosthodontics.
- Implants are another significant advancement in tooth replacement.
Definitions
- Dentulous: A person with natural teeth.
- Edentulous: A person who has lost natural teeth. Edentulous people may be partially or completely edentulous depending on the number of missing teeth.
Branches of Prosthodontics
- Fixed prosthodontics: Focuses on permanent restorations.
-
Removable prosthodontics: Features removable appliances.
- Complete denture prosthodontics: Replacement of all teeth.
- Partial denture prosthodontics: Replacement of some teeth.
- Implant prosthodontics: Focuses on dental implants.
- Maxillofacial prosthetics: Makes prosthetics for areas of the mouth and face, lost due to diseases or trauma.
Types of Prostheses
- Denture: A prosthesis that replaces one or more teeth and related structures. Dentures are partial, complete, or fixed/removable.
- Partial denture: A dental prosthesis used to replace some teeth.
- Fixed partial denture: A secure replacement that is permanently attached to natural teeth, roots, or dental implants. These are not removable.
- Removable partial denture: A prosthesis that replaces teeth within a partially dentate arch; removable.
- Complete denture: A removable prosthetic that replaces the entire dentition (all teeth) in the arch.
Reasons for Tooth Loss
- Traumatic injuries
- Dental caries (cavities)
- Gum disease
- Cysts and tumors
- Treatments involving radiation
- Iatrogenic extraction
- Congenital missing teeth
- Impacted teeth
Sequelae of Tooth Loss
- Resorption: The socket gradually reshapes to resemble the edentulous ridge.
- Tilting: Teeth may tilt following the loss of neighboring elements.
- Drifting: Teeth shift in their positions in the jaw.
- Occlusal disharmony: Discomfort, pain, or TMJ issues as a result of an uneven jaw alignment.
Treatment Options
- Preservation and prevention: Methods to maintain natural teeth.
- Post and core/crowns: Support for teeth with extensive loss.
- Implants: Support for restorations that are placed in the jawbone.
- Fixed partial dentures: Support for situations where several teeth have been lost, but support for the replacement is maintained by teeth that surround the missing teeth.
- Cast removable partial dentures: Support for situations where several teeth have been lost and the replacement requires attachments that maintain the replacement's position in the mouth.
- Overdentures: A denture that is supported over dental implants.
- Complete dentures: Full mouth replacements.
- Implant-retained dentures: Dentures secured by implants.
- Maxillofacial prostheses: Used to replace areas of the mouth and face that have been lost because of injury or disease.
Masticatory Loads
- Forces during chewing are substantially lower with dentures compared to natural teeth.
- Natural teeth can generate forces of up to 175 pounds but usually 40 to 50 pounds.
- Denture wearers exhibit masticatory forces in the range of 22-24 pounds.
- Forces generated by denture wearers are only 10-15% of those with natural teeth.
