Most of the orthodontic cases imply shortage of space and have some crowding. Non extraction treatment has become popular during the last decade however there are still considerable amount of cases needed treatment based on tooth extraction. The first phase of the treatment in premolar extraction cases is distalization of the canines. Using conventional orthodontic treatment techniques, biological tooth movement can be achieved with a limited rate (Reitan, 1967; Rygh, 1974). The canine retraction phase usually lasts about 6-8 months. Besides this, extra or intraoral anchorage mechanics are required to keep safe the obtained space during canine distalization, particularly in cases where maximum or moderate anchorage is required. Therefore, under normal circumstances conventional treatment with fixed appliances is likely to last about 20-24 months, and duration of the orthodontic treatment happens to be the most complained matter especially for the adult and young adult subjects.

Many attempts have been made in order to shorten the time for orthodontic tooth movement and overall orthodontic treatment time. In 1959, Köle reported combining orthodontics with corticotomy surgery in order to increase the rate of orthodontic tooth movement. Köle’s (1959) corticotomy-facilitated orthodontics technique was used and reported by several authors since then (Anholm et al. 1986, Gantes et al. 1990, Suya 1991, Wilco et al 2001). In 1980’s, increase in rate of tooth movement and periodontal cyclic nucleotide levels by combined force and electric currents studied by Dr. Davidovitch and co-workers (Davidovitch et al., 1980, Davidovitch et al. 1980). In 1998, Liou and Huang (1998), introduced the technique of distraction of periodontal ligament for rapid tooth movement. And finally in 1999, a new technique of rapid tooth movement by using the principles of distraction osteogenesis has been described and used by İşeri and Kişnişci namely dentoalveolar distraction (DAD) (İşeri et al., 2001; Kişnişci et al.; 2002, İşeri et al. 2005; Gürgan et al. 2005). In this chapter, detailed description of the DAD technique, data regarding the effects of DAD on the dentofacial structures and case reports are presented.
