Temporary Anchorage Devices in Clinical Orthodontics

Abstract

This chapter discusses scissor bite correction with temporary anchorage devices (TADs) in orthodontics. Scissor bite is a complete buccal crossbite caused by the combination of excessive maxillary width and a narrow mandibular alveolar process. It can occur unilaterally or bilaterally, and unilateral scissor bite may be accompanied by a midline discrepancy. The conventional treatment approach for correcting scissor bite is to use inter-arch elastics and a transpalatal arch, but inter-arch elastics can produce an unwanted extrusion of the second molars, as this method involves a vertical force vector. TADs and orthodontic mini-implants can be used as anchorage for various tooth movements and can be used as anchorage to effectively correct scissor bite without side effects. The midpalatal and palatal slope areas have sufficient vertical bone and are covered with a thin, uniform keratinized gingiva so the installation success rate is high.
