Gold is widely used in prosthetics. Its use ranges from being employed in the fabrication of removable dentures, where the inner surface permanently touching oral cavity tissues, through to fixed dentures, and even some structures of certain implantological systems. All such items can be made of galvanized gold. Thus, new technologies have made gold and its alloys a kind of a universal material.

Using metal alloys (gold alloys included) to make the framework for removable dentures is much better than using acrylic resin. This because the alloys have almost no destructive influence over the dentures bearing area. Due to the precise way it is made, the stability of shape, the lack of internal stresses and the close contact with the dentures bearing area, it is possible to achieve very good retention of the denture over a long span of time. Another advantage is that the metal framework conducts temperature changes and this facilitates keeping the tissues in good health. Also, a denture metal framework makes it much easier for the patient to maintain good oral hygiene by lowering the risk of plaque accumulation. However, a metal framework has a disadvantage as well - prosthesis relining cannot be made.
