Abstract
Abstract A metallic orthodontic wire is coated with a layer of tooth color material and a clear layer of material covers the tooth color material to allow the tooth color material to be seen through the layer of clear material. A preferred material for the tooth color layer is a plastic such as polyethylene or polyurethane. A preferred material for the clear layer is a silicone elastomer. Several processes for fabricating various embodiments of coated metal orthodontic wires are also disclosed.
