Abstract
A removable dental appliance may include an appliance body at least partially surrounding a plurality of teeth and an interproximal reinforcement. The appliance body may include a first shell shaped to engage a first tooth and a second shell shaped to engage a second tooth. The interproximal reinforcement extends from a first gingival edge on a labial side of the appliance body along an interproximal region between the first tooth and the second tooth to a second gingival edge on a lingual side of the appliance body. The interproximal reinforcement is configured to engage at least one of a lingual surface or labial surface of the first tooth below a height of contour to enable the appliance body to cause movement of the first tooth toward a desired position.
