The whole of all paraphernalia that are designed to replace a lost part of the body is called prosthesis. In dentistry the artificial items that are designed using the appropriate material to make up for the missing part in a tooth or to replace one or more lost teeth in order to restore the former efficacy, comfort, health and physical appearance are called dental prosthesis.

Prosthodontics (expertise in prosthetic dental treatment) is the field of dentistry which aims to compensate for the loss of tissue sustained in the event of an illness or accident and to offset the damage inflicted on the speech, physical appearance and functionality. Prosthodontics achieves this through the use of mouth and/or facial prosthesis.

In  Prosthodontics, missing part of tooth or one or more than one missing tooth and relevant tissues are replaced using appropriate restoration materials in order to gain missing function, aesthetic, comfort and health.

Basically, there are two types of dental prosthesis; fixed and removable prosthesis.
