The objetive of this study was to emphasize the orthodontists and periodontists relationship to enhance periodontal tissue during inishing and maintenance of orthodontic treatment results. The observation of the gingival tissue clefts during the extraction spaces closure phase can generate dificulties to inishing and stabilization of the adjacent teeth to the extraction sites. The relapse of the orthodontically moved teeth can probably be caused by the transeptal ibers. The correct root parallelism, a criterious ibertomy and immediate and adequate retention are indispensable procedures to achieve orthodontic treated cases stability. Better results are obtained with supracrestal ibertomy in severe rotated teeth and gingival hyperplasia in extraction sites preventing relapse in these region.
