Introducing Invisalign® Mandibular Advancement with Enhanced Precision Wings
A more durable3 and patient-friendly way to treat Class II malocclusions.
Invisalign treatment with mandibular advancement is meant for tweens and teens presenting with retrognathic Class II malocclusions in permanent dentition or stable late mixed dentition. The special feature of enhanced precision wings for Invisalign treatment with mandibular advancement are integrated into the Invisalign aligners.
Building upon years of experience treating and analyzing Class II malocclusions, we have added even more innovation to the design with new enhanced precision wings for Invisalign treatment with mandibular advancement.
