Abstract
Orthodontic treatments involve the fi xation of appropriate appliances, such as the lingual arch (LA), which acts as an anchor to stabilize and/or prevent the movement of a tooth. However, application of the LA and transpalatal arch both requires complex laboratory procedures owing to the use of multiple bands. A modified direct bonding LA was developed to simplify laboratory procedures and promote versatile designs. A mesh plate and tube were welded together, and the LA was then attached using the directly bonded mesh plate and tube. Since the LA was only directly bonded on the lingual side, it could be removed according to anchorage requirements without disturbing the labially fixed appliances.
