A dental bridge is an immovable replacement of one or more missing teeth. It is supported in remaining natural teeth, when both natural and artificial teeth are in a single common frame. Its frame is made from metal or zirconium. First of all, the cosmetic material simulating the color of the tooth is acrylic or ceramic / porcelain, while secondly it is zirconium. In contrast to mobile dentures, which can be removed and repositioned from the patient himself in the mouth, the dental bridges are permanently attached to the natural teeth.
