| 202 | Anatomical head-worn device for applying orthodontic force | US839630 | 1992-02-20 | US5203694A | 1993-04-20 | Paul E. Klein |
| An anatomical head-worn device is provided in the form of a bill cap, also known as a baseball cap. The cap includes one or more tension-device anchors for accommodating the attachment of orthodontic tension-applying devices used to direct tension force to selected parts of the head and mouth. The orthodontic forces are reacted against the head via the cap. The cap, when fitted snugly on the head, serves as a stable force base for applying forces in different directions on each side of the head. In one embodiment, tension-device anchors are mounted on the sides of the dome of the cap. In another embodiment, a downwardly-depending arm is supported on the bill of the cap. The arm extends in front of the face, and provides an anchor point for the application of protractive orthodontic foces. Use of an elastomeric orthodontic tension-applying device with the rigid arm extending in front of the face is also disclosed, including systems for non-positive engagement between the tension-applying device and the rigid arm. The non-positive engagement permits the instant release of orthodontic tension force if a mishap should occur which might otherwise injure the wearer. A releasable hook for securing a tension-applying device to only one side of the downwardly depending arm is also disclosed. In yet another embodiment of the cap, the tension-device anchors are mounted on the bill of the cap, which can then be worn backwards on the head to apply retractive orthodontic forces. The use of a bill cap makes the wearing of exterior orthodontic devices more socially acceptable to children and others, encouraging the user to accept needed orthodontic corrections. | ||||||
