Study Notes
Prosthetics
- The art and science of replacing missing body parts with artificial ones.
- A prosthesis refers to an artificial replacement for a missing body part.
Prosthodontics (Prosthetic Dentistry)
- Dental specialty focusing on diagnosing, planning, and restoring oral function, comfort, and appearance for patients with missing or deficient teeth and/or maxillofacial tissues.
- Utilizes biocompatible substitutes to achieve this.
Dentulous
- A person with natural teeth present in their mouth.
Partially Edentulous
- A person with some natural teeth missing.
Edentulous
- A person with no natural teeth remaining.
Denture
- An artificial substitute for missing natural teeth and adjacent tissues.
Removable Partial Denture (RPD)
- A removable prosthesis that replaces some missing teeth.
Fixed Bridge
- A non-removable prosthesis that replaces some missing teeth.
Implant
- A titanium post surgically placed into the jawbone to support an artificial tooth.
Complete Denture
- A removable prosthesis replacing all teeth and associated structures of either the maxilla or mandible.
Components of a Complete Denture
- Denture base: Supports the artificial teeth and rests on the underlying tissues.
- Artificial teeth: Resemble natural teeth and restore chewing function.
- Buccal flange: Portion of the denturebase that covers the outer surface of the cheek.
- Labial flange: Portion of the denturebase that covers the outer surface of the lips.
- Lingual flange: Portion of the denturebase that covers the inner surface of the tongue.
- Denture border: The outer edge of the denture that seals against the tissues of the mouth.
- Fitting surface: The area of the denture that contacts the underlying tissues.
Objectives of a Complete Denture
- Restoration of mastication: To restore normal chewing function.
- Appearance (esthetics): To restore the normal appearance of the face, especially the lower third.
- Correction of speech defects: Loss of teeth can lead to speech difficulties, addressed by correctly placing artificial teeth.
- Conservation of remaining tissue: To protect the remaining oral tissues from further damage.
- Patient satisfaction: To ensure that the patient is satisfied with the outcome.
Steps of Complete Denture Construction
-
Clinical Steps:
- Diagnosis (extra & intraoral): A thorough examination of the patient’s oral health and needs.
- Primary Impression: An initial impression taken using alginate to assess the mouth’s shape.
- Secondary Impression: A more precise impression taken using zinc oxide to accurately capture the tissues for the denture.
- Face Bow Record: To determine the position of the jaw bones in relation to the skull.
- Bite Registration: To record the patient’s bite and jaw movements.
- Tryin: A fitting appointment where the denture is tried in the mouth to ensure proper fit and appearance.
- Denture Delivery: The final denture is delivered to the patient after adjustments.
-
Laboratory Steps:
- Pouring Primary Impression: The primary impression is poured using dental plaster to create the primary cast.
- Special Tray Fabrication: A customized tray is made from acrylic based on the primary cast.
- Boxing & Pouring Secondary Cast: The secondary impression is boxed and poured with dental plaster to create the master cast.
- Occlusion Blocks: Wax blocks are used to establish the correct bite relationship.
- Mounting on Articulator: The master cast is mounted on an articulator, a device that simulates the movements of the jaw.
- Setting of Artificial Teeth: The artificial teeth are arranged based on the patient’s bite and appearance.
- Processing: The denture base is made using acrylic resin and processed to ensure durability.
- Laboratory Remount: The finished denture is mounted on the articulator to finalize occlusal adjustments.
Other Steps & Considerations
- Extraoral Diagnosis: Examining the patient’s face and head for any abnormalities or conditions that could affect the denture.
- Intraoral Diagnosis: A comprehensive oral examination to assess the health of the oral tissues and the extent of the edentulous area.
- Radiographic Examination: X-rays are used to assess the underlying bone structure and identify any potential problems.
- Primary Impression Materials: Impression materials used initially include, but are not limited to, irreversible hydrocolloid (alginate).
- Primary Cast: A cast made from the primary impression, used to create a customized tray for the secondary impression
- Block Out of Labial Undercuts: Undercuts on the master cast are blocked out, creating a smooth surface for the denture.
