A influência da manutenção da forma da arcada na recidiva do tratamento ortodôntico: uma revisão sistemática

Abstract

The orthodontic practice has a main basement to search for occlusal stability, in harmony with the muscular balance and craniofacial structures, aspects that are linked to anatomical characteristics and lower arch form. However many orthodontics believe that stable treatment is a myth. Studies of untreated normal occlusions have shown that the arch length decreases and increases the crowding of the incisors during life. The proposed of this systematic review is to assess whether maintaining the shape of the lower jaw and the distance intercanino and intermolar really ensures stability in the post-orthodontic treatment. The methodology was based on the Handbook for Systematic Reviews, the Cochrane Collaboration and the databases used were MEDLINE and LILACS. Of the 1511 articles found through the search strategy were selected through 312 articles and 13 abstracts and titles through the inclusion and exclusion criteria. Data were collected as sample, malocclusion, treatment type, sample intervals, professional (university / private), use of restraint, arch length, distance intercanino, intermolar distance, crowding and change the shape of the arch. The result was that most of the articles concluded that there is a decrease in arc length, and distance intercanino intermolar after orthodontic treatment, while maintaining the original shape of the arc before treatment. Thus, it was concluded that there will be recurrence, with reduced width and intermolar intercanino, decreased arch perimeter, with consequent crowding, therefore it is necessary to maintain the containment bottom indefinitely.
