Orthodontic appliance

Claim 2

An orthodontic appliance comprising: a base having an inwardly facing surface on one side thereof adapted for attaching the appliance and a body portion extending outwardly from the other side of said base; said body portion having one embodiment substantially shorter than a corresponding dimension of the base; a pair of wings, each wing extending in opposite directions from the body portion and having a length extending substantially beyond the body portion to define wire receiving slots between the base and the ends of said wings; the wings defining an outwardly facing domed surface which is curved in at least one direction and which thereby presents a comfortable surface to the mouth tissue of the patient; and a cross slot extending into said body portion between the wings and configured to receive therein a dental appliance of predetermined dimensions, the cross slot having a curved surface between the bottom of the cross slot and the sides of the cross slot to reduce stress concentrations.

Claim 3

The orthodontic appliance according to claim 1 wherein the inner surface of the base is adapted for bonding directly to the tooth of a patient, and further including an aperture formed in the inner surface of the base for receiving a quantity of bonding material.

Claim 4

The orthodontic appliance according to claim 2 wherein the aperture in the base has a substantially noncircular configuration and thereby serves to prevent rotation of the appliance relative to the tooth.

Claim 5

The orthodontic appliance according to claim 1 wherein the width of the body is substantially equal to the width of the base and the width of the wings is substantially narrower than the width of the base.

Claim 6

The orthodontic appliance according to claim 1 wherein the entire appliance comprises a unitary molded structure formed from a material selected from the group including ceramics and metals.

Claim 7

The orthodontic appliance according to claim 5 wherein the appliance is formed from aluminum oxide.

Claim 9

An orthodontic appliance comprising: a base having an inwardly facing surface on one side thereof contoured for bonding directly to the tooth of a patient; said base including a body portion extending from the other side of the base, the body portion having a length substantially shorter than the length of the base and a width substantially equal to the width of the base; a wing extending in each of opposite directions from the body portion, each wing having a length extending substantially beyond the length of the body to define wire receiving slots between the base and the ends of said wings; the wings defining an outwardly facing dome surface which is generally curved in at least one direction and which thereby presents a comfortable surface to mouth tissues; a cross slot extending into said body portion between the wings and configured to receive therein a dental appliance of predetermined dimension, the cross slot having a curved surface between the bottom of the cross slot and the sides of the cross slot; and the entire appliance comprising a unitary, molded structure.

Claim 10

An orthodontic appliance comprising: a base having an inwardly facing surface on one side thereof contoured for bonding directly to the tooth of a patient; said base including a body portion extending from the other side of the base, the body portion having a length substantially shorter than the length of the base and a width substantially equal to the width of the base; a wing extending in each of opposite directions from the body portion, each wing having a length extending substantially beyond the length of the body to define wire receiving slots between the base and the ends of said wings; the wings defining an outwardly facing dome surface which is generally curved in at least one direction and which thereby presents a comfortable surface to mouth tissues; a cross slot extending into said body portion between the wings and configured to receive therein a dental appliance of predetermined dimension, the cross slot having a curved surface between the bottom of the cross slot and the sides of the cross slot; and the entire appliance comprising a unitary, molded structure.

Claim 11

The orthodontic appliance according to claim 8 wherein the appliance is transparent to allow the color of a tooth to be visible through the appliance so as to cause the appliance to be substantially inconspicuous to the eye.
