Abstract

Anterior open bite (AOB) with mild-to-moderate skeletal discrepancies can be camouflaged by an orthodontic tooth movement. Conventional methods can improve occlusal relationships and some profile esthetics, but their mechanics may result in detrimental side effects such as a gummy smile, a high-frequency relapse, and an unfavorable facial profile. The emergence of temporary skeletal anchorage devices (TSADs) has facilitated the treatment of skeletal Class II AOB through intrusion of the posterior teeth and autorotation of the mandible, improving facial esthetics while minimizing the side effects. TSADs can also simplify treatment plans and offer a more predictable treatment result. Finite element studies have identified the location of the center of resistance of the dentition, providing a biomechanical basis for understanding 3-dimensional tooth movement patterns using TSADs. Therefore, biomechanical and clinical considerations are essential for correcting Class II AOB using TSADs.
