Treatment of Skeletal Class III Malocclusion with the Biofunctional System
Volume 49 : Number 11 : Page 717 : Nov 2015
When a skeletal Class III malocclusion is diagnosed early enough, the preferred treatment is orthopedic, involving maxillary traction with facemasks - often combined with rapid maxillary expansion - followed by orthodontic correction using Class III elastics. If the problem is not diagnosed until the permanent dentition, however, the treatment options are limited to compensatory or surgical-orthodontic therapy. Surgical treatment may produce the most esthetic results, but is less commonly performed because of its risks and expense.

Compensatory Treatment of a Complex Class III Malocclusion
Volume 56 : Number 2 : Page 20220201 : Feb 2022
Recent technological advances in thermoactivated and superelastic wires and skeletal anchorage have enabled simpler compensatory orthodontic treatment of skeletal Class III patients without extractions or orthognathic surgery. In this case, the authors use passive self-ligating brackets and extra-alveolar mandibular skeletal anchorage.
