Serial extraction procedure, when cautiouly practiced in severe discrepancy case, can be a good clinical approach, but the treatment planning must always be based on accurate analysis of all conditions, especially patient¡¯¡¯s individual growth pattern and his family development. It is most difficult to determine the timing and selection of most effective sequence of deciduout extraction. It is the best candidate that patient is with class I malocclusion with harmony of the skeletal and muscular system and severe discrepancy of the tooth system. The authors have observed a female, who has complained of the malalignment of mandibular permanent incisor teeth. Serial extraction has been performed to relieve it through adequate various informations and resulted in a fairly good prognosis.
