Dental prosthesis is a term used to refer to various dental appliances designed to replace missing teeth, gums, or other oral structures. There are several synonyms that can be used to describe dental prosthesis, such as Dental implants, dentures, bridges, and dental crowns. Dental implants involve placing a metal rod or screw in the jaw, where it serves as an anchor for a prosthetic tooth or teeth. Dentures are removable devices that are used to replace missing teeth. Bridges are fixed prosthetic devices that are used to replace one or more missing teeth. Dental crowns provide a tooth-shaped cap that is placed over the existing tooth or implant to restore its size, shape, and function.
