Anterior open bite (AOB) can be corrected by orthognathic surgery or orthodontic treatment. Severe skeletal, facial, and functional problems should be corrected by orthognathic surgery, but combining cone-beam computed tomography (CBCT) and temporary anchorage devices (TADs) can provide an efficient and accurate way to correct AOB. Nowadays, by using TADs, we can expand orthodontic boundaries. In this lecture, various clinical applications of TADs and orthognathic surgery will be discussed in challenging AOB cases along with new American Board of Orthodontics (ABO) Scenario-based Oral Clinical Examination domains. After the lecture, clinicians will be able to treat and finish anterior open bite cases more efficiently and successfully while minimizing the chance of relapse.
