Correction of Asymmetric Malocclusions with Dental VTO and TADs

Without sound objectives and proper planning, anchorage requirements could easily be overlooked in asymmetric dental malocclusions. While cephalometric analyses are helpful in providing a rough estimate of skeletal and dental relationships, treatment goals need to be developed accordingly with the face and ultimate position of the incisors. In essence, the primary key to success in asymmetric cases is to identify the direction and amount of dental movements required within each quadrant properly. In this presentation, the use of virtual treatment objective (VTO) in conjunction with temporary anchorage devices to support conventional treatment mechanics (TADs) will be demonstrated.

Learning Objectives:

• Recognize the differences in anchorage planning between symmetric and asymmetric malocclusions.
• Gain an appreciation of controlling the amount of tooth movement in each arch quadrant.
• Apply various TAD placement strategies in asymmetric malocclusions.
