The first step of treating open bite malocclusion is to determine whether the bite deformity is of dental or skeletal origin. With the assistance of skeletal anchorage devices, some skeletal open bite malocclusions can be treated without surgery. To improve the efficacy and efficiency for this clinical difficulty, it is crucial to differentiate where the offending site is: upper or lower; anterior or posterior. Then a solution of anterior extrusion or posterior intrusion can be delivered properly according to the relative dentoalveolar problems. Various mechanics design and applications of TADs will be introduced in this lecture.
- Problem-oriented diagnosis and treatment planning.
- Effective mechanics design for molar intrusion.
