Abstract:
We present a case of bialveolar protrusion treated with second premolar extraction. The patient did not agree to placement of a visible labial appliance or to the use of a headgear. Therefore, a lingual orthodontic appliance was used, and titanium screws were placed into the buccal alveolar bone for orthodontic absolute anchorage and support of en masse retraction of the anterior teeth. Cephalometric superimposition and panoramic radiographs showed little anchorage loss and good occlusion at the end of treatment. Our results suggest that lingual treatment combined with a screw-type implant anchorage provides reliable and comfortable results for those seeking invisible treatment.
