Introduction: The treatment of crowding of maxillary and mandibular anterior teeth commonly suffers relapse. Therefore, major studies focus only on stability of mandibular anterior segment. Objective: This article propose a review and critical analysis of the literature, emphasizing the etiologic factors of incisors crowding, the various treatment plans and the relapse of the maxillary anterior segment, considering the treatment protocols, the periodontal factors and the rapid maxillary expansion. Conclusions: The main factors influencing the relapse are the severity of the initial malocclusion, the changes in arch dimensions and the changes in physiology of periodontal tissue. The study of the causes of relapse is important to help in achieving a correct treatment planning and to predict the postretention stability.

Keywords: Relapse. Irregularity. Stability. Post-retention.
