Distalizing mandibular molars may be indicated for patients with minor skeletal Class III discrepancies or in Class III subjects with mild crowding. Traditionally, mandibular molar distalization was accomplished using elastics, open coils, and the multiloop edgewise archwire technique. In recent years, several techniques have been developed to reduce the dependence on patient compliance, such as skeletal anchorage. Recently, several reports have been published on mandibular distal movement using miniscrews and some case reports have shown the possibility of obtaining Class III correction with sequential mandibular distalization in non-growing subjects by means of clear aligners. However, a sound clinical judgment should always be made on the basis of a higher level of evidence. Therefore, the purpose of the present prospective study is to provide a detailed analysis of the underlying skeletal and dental changes determined by mandibular distalization therapy with the sequential Invisalign protocol in permanent dentition. This will be accomplished by testing the following null hypothesis: mandibular molar distalization is not achievable with aligners without the application of TADs.
