Prosthetics or prosthodontics is the treatment of dental defects, replacement of missing teeth or parts of the jaw with fixed replacements or removable prostheses.

Prosthodontics can basically be classified according to:

1. Fixed prosthodontics (e.g., crowns, bridges)
2. Removable prosthodontics (e.g., partial, model cast, full prostheses)
3. A combination of fixed and removable dental prostheses (e.g., attachment prostheses)
4. The support (parodontal, gingival, parodontal-gingival supported, implant-borne)
