Prosthesis may be defined as an artificial replacement of a missing part of the human body

Types of prosthesis

i. Dental prosthesis
ii. Maxillofacial prosthesis
iii. Ancillary prosthesis

Dental prosthesis

An artificial replacement of one or more teeth and associated dental/alveolar structures.

Fixed dental prosthesis

Any dental prosthesis that is cemented, screwed or attached to the retained natural teeth or roots.

Removable prosthesis

Any dental prosthesis that replaces some of the missing teeth in a partially edentulous arch

Removable partial denture prosthesis (RPDP)

The prosthesis that replaces some of the teeth in a partially edentulous arch and that can be removed from the mouth by the patient.

It can be a simple removable partial denture fabricated in acrylic resin called temporary partial
denture.

A removable partial denture fabricated in cast metal alloy and acrylic resin is called cast partial denture

Removable complete denture prosthesis

The prosthesis that replaces the entire dentition and associated structures of maxilla and mandible

Maxillofacial prosthesis

The prosthesis that is used to replace a part or all of any stomatognathic or craniofacial structures.

Examples of the maxillofacial prosthesis are auricular
prosthesis, orbital prosthesis, nasal prosthesis and facial prosthesis.

Implant supported prosthesis

The prosthesis that is used to replace the missing teeth , retained by implant supported prosthesis.

Ancillary prosthesis

The type of dental prosthesis used in prosthodontics for a very short term of usage

example- splints ,stents and guides
