Anterior open bite cases are very difficult to treat satisfactorily because of their multifactorial etiology and their very high relapse rate. Dependent on the origin of the anterior open bite malocclusion and the patient’s age, there are several treatment possibilities ranging from deterrent appliances, high-pull headgear, fixed appliances with and without extractions to orthognathic surgery, and skeletal anchorage with miniplates or minis crews. This article reviews and describes the prevalence, classification, etiology, treatment strategies and stability of open bite malocclusion.
