18 Years of Experience with the Skeletal Anchorage System (SAS)
Skeletal open bite is characterized by excessive lower facial height and extremely large interlabial gap. However, It has been extremely difficult to intrude molars and consequently difficult to reduce the excessive lower facial height. Therefore, surgical maxillary impaction has been the most effective treatment modality to correct open bite. Following development of temporary anchorage devices (TADs), orthodontists have been able to intrude molars and offering a non-surgical treatment option for open bite. However, such non-surgical approach is not necessarily easy, because most of open bite cases usually have not only vertical problems, but also some antero-posterior and transverse orthodontic problems. In this presentation, the strategy to solve those complex orthodontic problems in open bite will be discussed.
