Study Notes
Introduction to Prosthetics
- Prosthetics is the art and science of replacing missing body parts.
- A prosthesis is an artificial replacement for a missing body part.
- Prosthodontics (Prosthetic Dentistry) is a specialty that diagnoses, treats, rehabilitates, and maintains oral function, comfort, appearance, and health of patients with missing teeth or maxillofacial tissues.
- Dentulous refers to a mouth with natural teeth.
- Partially edentulous refers to a mouth with some natural teeth lost.
- Edentulous refers to a mouth without any teeth.
Denture Overview
- A denture is an artificial replacement for missing teeth and adjacent tissue
- Complete denture replaces all of the teeth and associated structures in the upper or lower jaw.
- Removable Partial Denture (RPD) replaces some teeth.
- Fixed Bridge replaces missing teeth with a fixed appliance.
- Implant is a surgical fixture that replaces the root of a tooth.
Denture Components
- Dentures are composed of a base and artificial teeth.
- The base is the part of the denture that rests on the gums.
- The base has three surfaces: polished surface, fitting surface, and occlusal surface.
- The buccal flange is the part of the base that covers the cheek.
- The labial flange is the part of the base that covers the lips.
- The lingual flange is the part of the base that covers the tongue.
- The denture border is where the base meets the gums.
Objectives of a Complete Denture
- Restore mastication function
- Improve facial aesthetics, especially the lower third of the face.
- Correct speech defects.
- Preserve the remaining tissue in the mouth.
- Patient satisfaction.
Construction Steps: Clinical
- Diagnosis (extra & intraoral): assess the patient's oral health and needs.
- Primary impression: make a preliminary impression to assess the mouth's shape.
- Secondary impression: make a more precise impression after customizing the tray.
- Face bow record: establish the relationship between the jaw and the skull.
- Bite registration: record the relationship between the upper and lower teeth.
- Try-in: assess the fit and appearance of the denture before processing.
Construction Steps: Laboratory
- Pouring primary impression: create a cast from the primary impression.
- Special tray on cast: use a custom tray to make a more precise impression.
- Boxing and pouring secondary cast: create a cast from the secondary impression.
- Occlusion blocks: create a template to guide the setting of the artificial teeth..
- Mounting on articulator: mount the cast on a device that simulates jaw movements.
- Setting of artificial teeth: arrange the teeth in a specific position.
- Processing: fabricate the denture from acrylic resin.
- Laboratory remount: adjust the denture after processing to ensure proper fit and occlusion.
- Denture delivery: deliver the denture to the patient.
Radiographic Examination
- Radiographic examination helps to evaluate the bone density, identify any potential issues, and assess the position of remaining teeth.
