Extra-alveolar Total Arch Movement & Intentional Symphysis Remodeling in Children for Redirecting Growth

Conventional orthpedic treatment for children with skeletal discrepancies has largely lead to unfavorable soft tissue profile, such as lip protrusion, lip incompetency and/or unattractive chin position. The question is whether major change in the profile can be attained during the second phase of treatment. We propose an extra-alveolar total arch movement including major remodeling in the lingual cortical plate, mandibular symphysis to reverse unwanted growth occured during Phase I treatment. For most ‘borderline’ cases between extraction and nonextraction, and between surgery and nonsurgery cases, may benefit from the precise four-dimensional total arch movement. A ‘beyond-the-border’ type tooth movement will also be introduced to advocate redirection of the jawbone growth.
