Mandibular Advancement with Aligners

Mandibular advancement is one of the most sensitive and technique-dependent phases in Class II treatment with aligners. Predictability depends entirely on proper preparation, correct sequencing, and strict biomechanical control.

This protocol is entirely dedicated to Mandibular Advancement and covers:

• Pre-MA phase essentials: overjet creation, arch coordination, elimination of interferences in all three planes
• How to avoid premature or asymmetric mandibular jumps
• Recommended number of aligners and jump magnitude for stability
• Attachment design and anchorage strategies during MA
• Use of elastics for stabilization and transition phases
• Common causes of failure: posterior open bite, misfitting precision wings, loss of anchorage
• Retention strategy after MA to maintain mandibular position

This protocol is built to help you perform mandibular advancement safely, gradually and predictably, reducing complications and increasing long-term stability when treating Class II cases with aligners.
