Abstract

Background: In orthodontics, tooth crowding and space problems are common, with many patients requiring premolar extraction. Canine distalization is crucial, but traditional methods offer limited tooth movement and anchorage loss. The present study aimed to evaluate the biomechanics of rapid canine distalization in a dental distraction (DD) technique using a readymade distraction device.

Materials and Methods: Seven adult female patients who required the extraction of their bilateral maxillary first premolars as part of their orthodontic treatment plan participated in the study. Distalization of 14 maxillary canines was accomplished using the readymade distraction device, ‘PiTractor’, once the distraction undermining surgical procedure was completed. Cone-beam computed tomography (CBCT) images were taken before distraction and after a consolidation period to evaluate the three-dimensional (3D) positional changes of the maxillary canines and first molars.

Results: The maxillary canines were distalized by an average of 5.2 mm after 12–19 days, with a significant (mean [SD]) distal tipping (9 [3.8])°, buccal rolling (4.8 [2.4])° and distal rotation (7.3 [5.6])°. However, the maxillary first molars showed insignificant positional changes of (0.5 [0.4]) mm and (0.2 [0.3]) mm for horizontal and vertical anchorage loss, respectively.

Conclusions: The ‘PiTractor’ distraction device successfully achieved rapid canine distalization with minimal posterior anchorage loss. However, significant combined distal tipping, buccal rolling and distal rotation of the distracted canines were detected.
