摘要： An orthodontic bracket or similar orthodontic appliance is made of a polycrystalline aluminum oxide having a translucency which minimizes visibility of the bracket when mounted on a tooth. The bracket is formed by pressing powdered high purity aluminum oxide plus sufficient magnesium oxide for controlling grain size, and sintering the resultant compact in hydrogen to yield a high density aluminum oxide bracket. The substantially color-free bracket has desirable strength and other mechanical properties combined with a translucency which permits the natural color of the tooth to show diffusely through in a fashion tending to make the bracket blend with and disappear against the tooth.
