Abstract
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.
For maximum total mandibular arch distalization in protrusion patients, it is recommended
to extrude and distalize the molars simultaneously, which results in more posterior
movement of the mandibular dentition without gingival impingement. Therefore, this
paper presents efficient biomechanics, a strategy, and the anatomy of the retromolar
area for total arch distalization using TSADs to improve facial profile without extracting
premolars in Class II maxillary and bimaxillary protrusion patients.
