Anterior Crossbite Treatment with a Self-Ligating Bracket System
Pp. 179-200 (22)
Anterior crossbite in the permanent dentition may be due to abnormal inclination
of the maxillary and mandibular incisors, occlusal interferences, or skeletal discrepancies of
the maxilla and/or mandible. Traditionally Class III patients are treated with lower
premolar extraction. When extractions are performed only in the mandibular arch, special
attention should be paid to the torque of the lower incisors to prevent excessive lingual
tipping. Gingival recession may occur with excessive retraction of the lower incisors to
close extraction space(s). The use of a self-ligating bracket system may have advantages for
treating crossbite associated with both Class III and Class I malocclusions. The play
between the main arch wire and the bracket slot provides mechanical freedom to facilitate
tooth movement. Clinical cases are presented to demonstrate this technique for correcting
Class III and Class I malocclusions with anterior crossbite.
