For more than a century, orthodontists have tried to stimulate growth of the mandible by so-called functional or orthopedic appliances. However, dento-alveolar compensations are responsible for poor skeletal changes. Proclination of the lower incisors can be avoided by combining functional appliances with skeletal anchorage in the mandible. This leads to true mandibular lengthening, glenoid fossa modeling, and mandibular rotation, quantified by 3D imaging.
Learning Objectives:
After this session, attendees will be able to:
Evaluate the effects of conventional Class II orthopedic appliances.
Demonstrate the impact of skeletal anchorage on dento-alveolar compensations by orthopedic appliances.
Evaluate the growth outcome of Class II orthopedics using 3D imaging.
