Enhanced Vertical Control -Temporary Anchor Devices with Clear Aligners

A common misconception that orthodontists have is that clear aligners are unable to treat complex cases such as open bite, deep bite, and skeletal malocclusions. Clear aligners have continually developed to overcome biomechanical limitations. Features such as attachments and auxiliaries, such as buttons and cutouts for elastics are designed to generate a complex force system. Additionally, temporary anchorage devices provide enhanced anchorage for the correction of sagittal and vertical problems. 

In this presentation, I demonstrate how clear aligners can deliver excellent results in managing vertical control such as severe open bite and deep bite. Surgical cases also require vertical control of teeth for decompensation. I will present clinical tips on how clear aligners can be used for vertical control in patients with dentofacial deformities, such as skeletal Class III and facial asymmetry, who underwent orthognathic surgery. Lastly, I will share clinical tips on how TADs can be utilized in the vertical control treatment, including treatment philosophy, how to determine if TADs are needed, timing, and biomechanics.
