A prosthesis is an artificial tooth that is instead of an aesthetically impaired tooth or teeth. The aim of prosthesis applications is to make artificial teeth that are compatible with the face of the person, closest to nature, and capable of performing chewing and speaking functions.

Prosthesis made as a result of loss of teeth can be stable or mobile. Prostheses such as crowns and bridges which are made on the teeth remaining in the mouth and cannot be removed by the patient are stable. Prostheses that can be inserted and removed at any time by the patient are called removable dentures.
