Impact of molar teeth distalization with clear aligners on occlusal vertical dimension: a retrospective study

open access: yesBMC Oral Health, 2019
A common strategy in the non-extraction treatment of Class II molar relationship is maxillary molar distalization, which could increase lower face height and cause clockwise mandibular rotation.
