Use of clear aligners to correct a variety of types of orthodontic malocclusion has become widely accepted by dental professionals. Some clinicians, however, have expressed the opinion that aligners are not an effective treatment for certain complex corrections, for example the appropriate closure of large (≥ 3 mm) interdental spaces. This article presents a case in which multiple large (3 to 5 mm) spaces were optimally closed using aligners only. An auxiliary technique utilising elastics and orthodontic buttons is also presented to show how non-tracking teeth can be effectively repositioned to be in the proper position in the aligner.
