Patent ID: 8485816

Claim:
A method for adjustment a patient's tooth using an orthodontic appliance, comprising: securing an orthodontic appliance to a patient's tooth, wherein the appliance includes: (a) a tooth attachment side for attaching to a tooth, and an outer side for facing away from the tooth; (b) mesial and distal archwire retaining portions for retaining an archwire in a first archwire retaining channel, each of the mesial and distal archwire retaining portions having a corresponding recess for receiving the archwire; (c) a first retaining ridge for holding the archwire in the corresponding recesses, the first retaining ridge extending away from the tooth attachment side further than distal and mesial ends of the first archwire retaining channel; (d) second mesial and distal archwire retaining portions for retaining a second archwire in a second archwire retaining channel, each of the second mesial and distal archwire retaining portions having a corresponding additional recess for receiving the second archwire; (e) a first bridge extending between and fixedly connecting the mesial archwire retaining portion and the second mesial archwire retaining portion; (f) a second bridge extending between and fixedly connecting the distal archwire retaining portion and the second distal archwire retaining portion; and (g) wherein the each of the first and second bridges enclose a part of an archwire retention channel between the first and second archwire retaining channels; providing the archwire in an open side along a length of the first archwire retaining channel for receiving the archwire in the first archwire retaining channel; applying a force to the archwire for inducing a predetermined second bow therein when the archwire enters the first archwire retaining channel, wherein the mesial and distal archwire retaining portions are on a first side of the first archwire retaining channel, and the first retaining ridge is on an opposing second side of the first archwire retaining channel, and contacts the archwire at a location between the mesial and distal archwire retaining portions for providing the predetermined bow in the archwire in a direction toward the first side; providing the second archwire in an open side along a length of the second archwire retaining channel for receiving the archwire in the second archwire retaining channel; applying a force to the second archwire for inducing a predetermined bow therein when the second archwire enters the second archwire retaining channel, wherein the second mesial and second distal archwire retaining portions are on a first side of the second archwire retaining channel, and a second retaining ridge is on an opposing second side of the second archwire retaining channel, and contacts the second archwire at a location between the second mesial and second distal archwire retaining portions for providing the predetermined second bow in the second archwire in a direction toward the first side of the second archwire retaining channel.
