<P>PROBLEM TO BE SOLVED: To provide an improved system and method for removably attaching a dental positioning appliance. <P>SOLUTION: There are provided an improved system and a method of removable attaching a dental positioning appliance (105) to the dental features (103) of a patient during orthodontic treatment. The removable dental positioning appliance (105) is often preferred over conventional braces for tooth repositioning due to comfort, appearance, and ease of use. The appliance (105) functions by applying force to specific surfaces of the teeth or dental features (103) to cause directed movement. However, the type of movement and 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 sufficient 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 features (103) to provide the appropriate physical features. <P>COPYRIGHT: (C)2012,JPO&INPIT |
