Serial extraction is a guided, progressive removal of deciduous teeth ahead of the time that they would normally be shed, "robbing Peter to pay Paul" to enlist the fundamental phenomena of adaptability and adjustment. By means of adaptability, providing room for certain teeth, there is an autonomous adjustment in the tooth position in Class I malocclusions. The technique is biologically sound, proven, and should not be considered a compromise. The objectives of establishing the integrity and proper position of the maxillary and mandibular incisors with the removal of deciduous canines are valid ones. The goal is to harmonize the defective tooth system with the normal muscle and bone systems in Class I malocclusions. The removal of deciduous first molars permits the early eruption of first premolars. If arch length is still obviously deficient, according to adequate diagnostic information available at that time, the first premolars are removed to allow the canine teeth to migrate distally into normal positions and to permit space closure by the mesial drift of the teeth posterior to the extraction site. In almost all instances, conventional orthodontic therapy is required to complete the alignment of teeth, to parallel the roots on either side of the extraction space, to eliminate overbite, and to effect residual space closure. However, such mechanotherapy is usually of significantly shorter duration, it is likely to produce less damage, and the results are more stable.
