Active Vertical Control with TADs in Hyperdivergent Class II Malocclusions
Date
April 23, 2023
The keys to harmonizing the lower faces of hyperdivergent Class II malocclusions include not to extrude the molars, upright the lower incisors, and control the anterior dental heights. TADs have been powerful tools to further reduce dental heights via intrusion, in combination with maximal retraction, to improve lip competence and chin projection via CCW rotation of the mandible.
Learning Objectives
- Understand the rationales of active vertical control.
- Comprehend the biomechanics of active vertical control.
- Apply TADs to harmonize the lower face in hyperdivergent Class II malocclusions.
