摘要:
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 patients lower dental arch to exert a force between the patients maxilla and mandible.
