“…In contrast, the option of using local orthodontic space closure without contralateral extraction has only been addressed by a few case reports [1,8,9]. In fact, some authors have even warned against refraining from counterbalancing extractions [14], or against attempting local space closure, unless recognized preconditions for extraction therapy are met [2].…”
