Comparative Effects of Mandibular Advancement With Invisalign Enhanced Precision Wings and Twin Block Appliance on Dentofacial Structures

Both TB and Invisalign MA-EPW appliances were effective in correcting skeletal Class II malocclusion in growing patients. The TB appliance showed greater efficiency relative to treatment duration, whereas the MA-EPW appliance provided superior lower incisor control and clinically relevant transverse expansion. Further long-term randomised controlled trials with defined and standardised protocols are needed to validate the clinical outcomes of mandibular advancement with clear aligners.
