Improved facial profile with non-extraction treatment of severe protrusion using TSADs

Extraction has traditionally been necessary to correct bimaxillary and lip protrusion with proclined maxillary and mandibular incisors. However, non-extraction treatment using temporary skeletal anchorage devices (TSADs) is now an option for severe overjet or full-step Class II malocclusions. It is possible to treat bimaxillary protrusion with non-extraction, but for successful non-extraction treatment in bimaxillary patients, the amount of total arch distalization of the mandibular dentition is crucial.
