Abstract
Orthodontic systems and methods involving segmentary shells are disclosed. Examples of the systems and methods are particularly focused on applying a distalization force to a segment of teeth in a posterior lateral sector.
Claims10
A method for treating a malocclusion, comprising:
- providing a series of consecutive left segmentary shells,
- providing a series of consecutive right segmentary shells,
- fitting a first left segmentary shell of the series of left consecutive segmentary shells to a left segment of teeth in a left posterior lateral sector of one of a maxilla and a mandible,
- fitting a left anchor on a tooth on a left side of the other of the maxilla and mandible,
- fitting a first right segmentary shell of the series of right consecutive segmentary shells to a right segment of teeth of a right posterior lateral sector of one of the maxilla and the mandible, and
- fitting a right anchor on a tooth on a right side of the other of the maxilla and mandible,
- the left and right segments of teeth comprising between two and six adjacent teeth and extending from a canine or premolar to a premolar or molar of the left and right segments of teeth, wherein
- there is no connection between the left and right first segmentary shells, and
- applying a distal force to the left and right segments of teeth with the first left and right segmentary shells fitted on the left and right segments of teeth respectively for a first period of time by providing a left and right resilient traction element between the left and right anchors and the left and right segmentary shells respectively or a retention feature bonded to a tooth of the left and right segments of teeth respectively,
- replacing the first left and right segmentary shells with second left and right segmentary shells of the series of left and right consecutive shells and applying distal force to the left and right segments of teeth with the second segmentary shells fitted on the left and right segments of teeth respectively for a second period of time, and wherein
- the series of consecutive left and right segmentary shells do not apply corrective forces other than distal forces to the canine and the premolar.

A method for treating a malocclusion of a patient comprising:
- a first treatment for treating a class II malocclusion to arrive at a class I malocclusion, and
- a second treatment for resolving the class I malocclusion, wherein the first treatment comprises:
- providing a series of consecutive segmentary shells,
- fitting a first segmentary shell of the series of consecutive segmentary shells to a segment of teeth in a posterior lateral sector of a maxilla, the segment of teeth comprising between two and six adjacent teeth and extending from a canine or premolar to a premolar or molar the segment of teeth,
- fitting an anchor in a mandible,
- applying a distal force to the segment of teeth with the first segmentary shell fitted on the segment of teeth for a first period of time by providing a resilient traction element between the anchor and the segmentary shell or an attachment bonded to a tooth of the segment of teeth,
- replacing the first segmentary shell with a second segmentary shell of the series of consecutive shells to the segment of teeth and applying a distal force to the segment of teeth with the second segmentary shell fitted on the segment of teeth for a second period of time, and
- removing the second segmentary shell after the second period of time,
- wherein during the first treatment, the first and second segmentary shells only apply distal forces to the segment of teeth in the posterior lateral sector of the maxilla,
- wherein the second treatment comprises providing a series of complete shells for the maxilla,
- wherein the complete shells are shaped to correspond to consecutive positions of the teeth of the maxilla in the second treatment, and
- wherein the first and second segmentary shells provide the distal forces only to the segment of teeth in the posterior lateral sector.
