How Are Metal Dentures Made?

How Metal Dentures Are Made

First, an impression of the jaw is made using an electrically non-conductive material. The impression's inner wall is treated with a heated low-melting alloy and the interior is stuffed with filling material. Fixing pins are inserted if there are crowns, casings or bridges. An electric conductive coating is then made by vaporizing the metal layer and spraying lacquer. The actual dentures are separated from the impression and forged with the intermediate metal base.

Metal Advantages

Metal is heavier and produces a more natural feeling. Metal bases are stronger than plastic and more durable. Metal dentures are also easily relined (if they are modified) and hypoallergenic. They can include a soft liner, but it must be replaced every year. Weight can contribute to more stability.

Metal Disadvantages

Non-modified metal dentures are difficult to reline. They are more costly than plastic.
