A dental prosthesis is an intraoral (inside the mouth) prosthesis used to restore (reconstruct) intraoral defects such as missing teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate. Prosthodontics is the dental specialty that focuses on dental prostheses. Such prostheses are used to rehabilitate mastication (chewing), improve aesthetics, and aid speech. A dental prosthesis may be held in place by connecting to teeth or dental implants, by suction, or by being held passively by surrounding muscles. Like other types of prostheses, they can either be fixed permanently or removable; fixed prosthodontics and removable dentures are made in many variations. Permanently fixed dental prostheses use dental adhesive or screws, to attach to teeth or dental implants.

Prosthesis is the dental field where artificial teeth are placed instead of missing teeth. Fixed or moving prosthesis are made according to the number of missing teeth, missing teeth and the condition of surrounding tissues. By applying an implant, with a correct evaluation, both fixed and mobile prosthesis can be made. Immediately after a short period of dental defects come into play, it is absolutely necessary to make a prosthesis. Because after the teeth have been lost, the remaining teeth may be spaced, extended, and later difficult to correct. Regular dental surveillance is very important after prostheses are made.
