The terminology “serial extraction” in Orthodontics was first described in the late 1920’s when Kjellgren  decided to plan the extraction of certain deciduous and permanent teeth at early stages of the dentition development. Since the extractions are under taken at the transitional dentition. This type of treatment is defined as “Early Treatment” in Orthodontics . The main indication for this treatment approach is for patients with severe crowding caused by tooth size arch discrepancies [3,4]. In other words, when maxillary and/or mandibular arches cannot accommodate teeth, extraction becomes an interesting option.
