Abstract

Many efforts have been made to correct scissors-bite and establish proper molar interdigitation for prosthetic or orthodontic treatment. The critical procedures for scissors-bite correction are intruding and palatally tipping the involved tooth when it is both extruded and buccally flared. Conventional approaches give rise to problems such as repetitive bonding failure and loss of anchorage. A newly designed spring, the dragon helix appliance, is used with an indirect skeletal anchorage system to correct scissors-bite. This spring provides effective tooth movement and the convenience of a simple and small design. We report a successful treatment with the dragon helix.
