Improved systems, and methods of removable attaching a dental positioning appliance (105) to the dental features (103) of a patient during orthodontic treatment. Such removable dental positioning appliances (105) are often preferred over conventional braces for tooth repositioning due to comfort, appearance, and ease of use. These appliances (105) function by applying force to specific surfaces of the teeth or dental features (103) to cause direct movement. However, the type of movement, the level of force applied is usually dependent on the surface characteristics, and positions of the dental features (103). In many cases, these aspects are inadequate to provide sufficient anchoring or to impart considerable force on the teeth (103) to be repositioned. Such limitations may be diminished with the use of one or more attachment devices (100) which may be positioned on the teeth or dental feature (103) to provide the appropriate physical features.
