Retention is a culmination of all our orthodontic knowledge. First-grade students initially learned both concepts at a high level of mastery, although retention was more problematic for them, especially with respect to opportunity cost. Nothing gives an orthodontist greater professional joy then seeing their patients 10 years out of braces looking great! The sample was divided into two groups: early (mixed dentition) extraction of mandibular second premolars and late (permanent dentition) extraction of mandibular second premolars. Research over the past thirty years has shown that this is not true — there is no “right” position that can assure a permanent, unchanging result. One hundred and thirty patients who were orthodontically treated satisfied the inclusion criteria of having received a semipermanent retention were treated with FRC lingual retainers (Ribbond (®)). After 2 years all three retention methods were successful in retaining orthodontic treatment results.

Assessment at least 10 years postretention of sixty-five cases previously treated in the permanent-dentition stage with first-premolar extractions, traditional edgewise mechanics, and retention revealed considerable variation among patients. The long-term response to mandibular anterior alignment was unpredictable; no variables, such as degree of initial crowding, age, sex, Angle classification, etc., were useful in establishing a prognosis.
