A nonextraction treatment approach is described, in which the upper and lower arches were expanded to their original three dimensions using a trihelix expander, a lip bumper appliance, and a fixed orthodontic appliance. Retention was also planned in accordance with the original malocclusion, which inclued a full\u2010time\u2010wear upper wraparound retainer, upper and lower anterior fixed lingual retainers, upper frenectomy, and fibrotomy for rotated teeth.\n                    <jats:italic>Conclusion<\/jats:italic>\n                    . Severe malalignment of teeth does not necessarily require extraction treatment.
