Lecture Description

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) provides 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 the 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.

Learning objective

Discuss diagnosis and treatment planning, treatment implementation and management, and critical analysis and outcomes assessment in AOB cases;
Identify clinical situations in which CBCT imaging and TADs would be beneficial in AOB correction;
Understand clinical applications and biomechanical considerations of orthognathic surgery vs. TADs in challenging AOB cases
