3M ESPE Gold Anodized Crowns are made of medium-hard aluminum for temporary bicuspid and molar use. They are durable, and are packaged in a stackable tray for easy storage. The gold anodization reduces any metallic taste or galvanic shock for the patient. Gold Anodized Crowns will not easily deform due to their aluminum base, which also minimizes the risk of bite-through. They come pretrimmed with a parallel wall design to save the time normally required for belling the crown.
