Biologic and Biomechanical Rationale for Closing Openbites with TADs

  • Dr Jason Cope, United States

The skeletal openbite is a difficult case to treat. Whether by orthodontics alone or in combination with surgery, relapse is associated with both. Considering the costs and risks of surgery, and dwindling insurance benefits, other options are needed. The introduction of TADs has provided another alternative, whereby posterior teeth are intruded allowing openbite closure. But what is the relapse associated with treating skeletal malocclusions by dental intrusion? To date, several techniques have been advocated for closing openbites with TADs. Are they all the same? Are there special considerations? This will be addressed by reviewing the orthodontic and surgical literature, with several clinical examples.
