An orthodontic bracket is made from crystalline alumina, preferably crystalline alpha-alumina. The bracket comprises a base member for attaching to a tooth and a body member extending from the base member. The body member includes walls that define an archwire groove. The walls comprise crystalline alumina. The bracket has sufficient strength to withstand normal torquing forces imparted by an archwire.

Crystalline alumina orthodontic bracket

The adhesive strength of alumina brackets to acrylic adhesive cements is enhanced by forming an essentially silica coating on the bonding surface of the bracket by the steps of coating said surface with an organosilicon compound such as a silane and then pyrolyzing the organosilicon coating to volatilize the organic components thereof to thereby leave an essentially silica coating.

Adhesive primer for alumina brackets

Orthodontic brackets are made from ion exchange strengthened glass. In a preferred embodiment, the glass is a lithium alumino silicate srengthened with sodium ions.

Orthodontic brackets made from ion exchange strengthened glass

There is disclosed an orthodontic bracket including a base member for attaching to a tooth and a body member extending from the base member. The body member includes walls that define an archwire groove. The walls are made of single crystal alumina. Preferably, the entire bracket is made of single crystal alumina, and most preferably, single crystal alpha-alumina or sapphire.

A process for producing a dental restoration wherein a bonding agent is disclosed for bonding dental porcelain to a nickel-containing metal core. The bonding agent is aluminum powder and an inert organic liquid carrier.
