Prosthodontics
- Branch of dentistry concerned with replacing teeth and contiguous tissues or jaw structures by artificial devices to restore oral function, comfort, appearance, and health of the patient
- Has three main branches: removable, fixed, and maxillofacial prosthesis
Fixed Prosthodontics
- Branch of prosthodontics concerned with replacing and/or restoring teeth by artificial substitutes (cast prosthesis) that cannot be removed by the patient
- Technique used to fabricate a fixed prosthodontic appliance securely fixed to natural tooth/teeth or screwed to one or more dental implants/implant abutments to restore teeth function and esthetics
Aims of Fixed Prosthodontics
- Restore function of teeth; mastication and speech
- Restore esthetics
- Maintain oral health and integrity
Indications for Fixed Prosthodontics
- Badly broken down teeth
- Primary trauma
- Tooth wear
- Hypoplastic conditions (congenital or acquired)
Contraindications for Fixed Prosthodontics
- No absolute contraindication, but consider:
- When a more conservative approach can provide satisfactory results
- Patient's age and medical condition (e.g. young patients below 18, elderly and medically compromised patients)
- Patients with bad oral hygiene
Types of Cast Restorations
- Crowns (partial or full coverage)
- Bridges
- Inlays
- Onlays
- Veneers
Crowns
- Restores missing tooth structure of three or more axial surfaces and the occlusal/incisal surface of a tooth with a material such as cast metal alloy, ceramics, resin, or a combination of materials
- Anatomical crown: highest/topmost part of a tooth occlusal to the cementoenamel junction
- Clinical crown: part of the tooth that is visible in the mouth
- Dental crown: artificial replacement that restores missing tooth structure by surrounding part or all of the remaining structure with a material
Bridge
- Also called fixed partial dentures
- Dental prosthesis that is luted, screwed, or mechanically attached to natural teeth, tooth roots, and/or dental implants/abutments that provide primary support for dental prosthesis and restoring teeth in partially edentulous arch
- Consists of three components: retainer, pontic, and connector
Inlay and Onlay
- Inlay: fixed intracoronal restoration, a dental restoration made outside of the tooth to correspond to the form of the prepared cavity
- Onlay: fixed partial coverage restoration that restores one or more cusps and adjoining occlusal surfaces or the entire occlusal surface and is retained by mechanical or adhesive means
Veneer
- Thin lamination, shell-like dental material bonded to one side of the tooth to improve its appearance and/or restore its normal contour
Classification of Fixed Restorations
- According to retention:
- Extracoronal restorations
- Intracoronal restorations
- Intraradicular restorations
- Extracoronal restorations:
- Full coverage restorations
- Partial coverage restorations
- Intracoronal restorations:
- Inlays
- Onlays
- Intraradicular restorations:
- Post-retained restorations
- Implants
- According to material used:
- Ceramic restorations
- Metal-ceramic restorations
- Full metal restorations
- Resin restorations
