The conventional treatment of skeletal class ¥² malocclusion has been focused on the application of orthopedic force primarily to the mandible. Thus moderate Class ¥² malocclusions can be corrected by the anterior displacement of the maxilla and maxillary dentition, possibly by restricting the growth of the mandible or by changing its direction. The patients having skeletal Class ¥² molocclusion were treated with removable appliance £¦ fixed appliance for detailed tooth movement and the following results were observed :

1.The anterior crossbite was corrected.

2.The forward and downward growth of the maxillary complex was obtained.

3.The lingual tipping of the mandiblar incisors was performed and the mandible was rotated in the clockwise direction.
