Abstract
The present disclosure is directed to a dental appliance. The dental appliance includes a first band adapted for mounting about a first tooth, such as a second molar, the first band having a mesial hook facing toward a root of the first tooth. A second band is included, the second band adapted for mounting about a second tooth, such as a premolar, wherein the second band has a distal hook facing toward a crown of the second tooth. A spring is secured to, and extends between, the distal and mesial hooks. The spring may be a nickel titanium coil spring and have a length of about 13 mm. Other embodiments include a supportive rigid bar, a bi-lateral arrangement, and a method of applying the dental appliance.
Claims18
A dental appliance, comprising:
- a first band adapted for mounting about a first tooth, wherein the first band has a mesial hook facing toward a first direction;
- a second band adapted for mounting about a second tooth, wherein the second band has a distal hook facing toward a second direction, the second direction being a different direction than the first direction;
- and
- a spring secured to, and extending between, the mesial and distal hooks,
- wherein the mesial hook, the distal hook and the spring are axially aligned along a first imaginary plane,
- wherein the first imaginary plane extends through an occlusal surface of the first tooth and through an occlusal surface of the second tooth,
- wherein the spring is configured to be in compression between the mesial and distal hooks, thereby being configured to push the first and second teeth away from one another, and
- wherein the first imaginary plane extends through a center of resistance of the first tooth.
A method of applying a dental appliance, comprising the steps of:
- mounting a first band on and about a first tooth, wherein the first band has a mesial hook facing toward a first direction;
- mounting a second band on and about a second tooth, wherein the second band has a distal hook facing toward a second direction different from the first direction;
- and
- attaching a spring to the distal and mesial hooks such that the spring extends between the distal and mesial hooks,
- wherein the mesial hook, the distal hook and the spring are axially aligned along a first imaginary plane,
- wherein the first imaginary plane extends through an occlusal surface of the first tooth and through an occlusal surface of the second tooth, and
- wherein the spring is configured to be in compression between the mesial and distal hooks, thereby being configured to push the first and second teeth away from one another,
- wherein the first imaginary plane extends through a center of resistance of the first tooth.
