Abstract
An orthodontic appliance has a post attached to a first upper tooth, and a button with a recess attached to a second upper tooth. An elongated arm has an eye at one end through which the post is inserted to allow the elongated arm to rotate about the post, and a tip at the other end for removable insertion into the recess of the button. The length of the elongated arm is selectable to maintain a desired spacing between the first and second upper teeth (e.g., by cutting the tip of the elongated arm). An elastic extends from either the post or button to an attachment point on the patient's lower dental arch to exert a force between the patient's maxilla and mandible.
Claims25
An orthodontic appliance for use on a patient having an upper dental arch with a plurality of upper teeth and a lower dental arch, said orthodontic appliance comprising:
- a post attached to a first upper tooth;
- a button attached to a second upper tooth and having a recess extending partially into the button;
- an elongated arm with opposing first and second ends, having:
- (a) an eye at the first end through which the post is inserted to allow the elongated arm to rotate about the post, thereby providing articulation at the first end of the elongated arm;
- and
- (b) a tip at the second end for removable insertion into the recess of the button to maintain a fixed spacing between the first and second upper teeth, and provide articulation at the second end of the elongated arm, wherein the length of the elongated arm is selectable to maintain a desired fixed spacing between the first and second upper teeth;
- and
- an elastic extending from at least one of the post and button to the patient's lower dental arch to exert a force between the patient's maxilla and mandible to bias the mandible in a desired direction with respect to the maxilla while maintaining a fixed spacing between the first and second upper teeth.
An orthodontic appliance for use on a patient having an upper dental arch with at least one upper anterior tooth, at least one upper posterior tooth and a lower dental arch, said orthodontic appliance comprising:
- a post attached to an upper posterior tooth;
- a button attached to an upper anterior tooth and having a recess extending partially into the button;
- an elongated arm with opposing first and second ends, having:
- (a) an eye at a first end through which the post is inserted to allow the elongated arm to rotate about the post and provide articulation at the first end of the elongated member;
- and
- (b) a tip at the second end for removable insertion into the recess of the button to maintain a fixed spacing between the first and second upper teeth, and provide articulation at the second end of the elongated member, wherein the length of the elongated arm is selectable to maintain a desired fixed spacing between the upper posterior tooth and the upper anterior tooth;
- and
- an elastic attached to the upper anterior tooth and extending to a posterior portion of the patient's lower dental arch to bias the patient's mandible forward with respect to the patient's maxilla to bias the mandible in a desired direction with respect to the maxilla while maintaining a fixed spacing between the first and second upper teeth.
An orthodontic appliance for use on a patient having an upper dental arch with a plurality of upper teeth and a lower dental arch, said orthodontic appliance comprising:
- a post attached to a first upper tooth;
- a button attached to a second upper tooth and having a recess extending partially into the button;
- an elongated arm formed from a piece of wire having:
- (a) a loop at a first end of the elongated arm to form an eye through which the post is inserted to allow the elongated arm to rotate about the post and provide articulation at the first end of the elongated arm;
- and
- (b) a tip at a second end of elongated arm for removable insertion into the recess of the button to maintain a fixed spacing between the first and second upper teeth, and provide articulation at the second end of the elongated arm, wherein the length of the elongated arm is selectable by cutting the second end to a desired length to maintain a desired fixed spacing between the first and second upper teeth;
- and
- an elastic extending from at least one of the post and button to the patient's lower dental arch to exert a force between the patient's maxilla and mandible to bias the mandible in a desired direction with respect to the maxilla while maintaining a fixed spacing between the first and second upper teeth.
An orthodontic appliance for use on a patient having an upper dental arch and a lower dental arch with a plurality of teeth, said orthodontic appliance comprising:
- a post attached to a first tooth in a first of the dental arches;
- a button attached to a second tooth in the first dental arch and having a recess extending partially into the button;
- an elongated arm with opposing first and second ends, having:
- (a) an eye at the first end through which the post is inserted to allow the elongated arm to rotate about the post, thereby providing articulation at the first end of the elongated arm;
- and
- (b) a tip at the second end for removable insertion into the recess of the button to maintain a fixed spacing between the first and second teeth, and provide articulation at the second end of the elongated arm, wherein the length of the elongated arm is selectable to maintain a desired fixed spacing between the first and second teeth;
- and
- an elastic extending from at least one of the post and button to the patient's other dental arch to exert a force between the patient's maxilla and mandible to bias the mandible in a desired direction with respect to the maxilla while maintaining a fixed spacing between the first and second teeth.
