A new approach for evaluation of canine dento alveolar distraction using cone-beam computed tomography

Abstract

Objective:The aim was to evaluate and plan the canine dento alveolar distractions (DADs) with the use of cone-beam computed tomography (CBCT).Materials and Methods:5 patients are requiring 10 canine DADs were selected for the study. A custom-made DAD distractor was fabricated for the study. CBCT scans were taken prior to and post thedistraction. DAD parameters such as Canine retraction, canine and molar rotation, molar anchor loss and level of the osteotomy cut above the canine was evaluated.Results:Average canine retraction was 7.5 mm in 17 days, molar anchor loss was 0.5 mm, canine and molar rotations were 8° and 0.40° and thedistance of the osteotomy cut to the canine was1.93 mm.Conclusion:The CBCT can be used to accurately evaluate the canine DADtechnique.

Evaluation of maxillary alveolar bone changes following canine retraction with different types of orthodontic brackets (cone beam study)

“…It is generally accepted that tooth movement can occur either with the bone or through the bone. But the question that is of significant interest and always strikes orthodontist is whether "bone traces tooth movement" or, more specifically, when an orthodontic tooth movement occurs, the bone surrounding the alveolar socket always remodel to an equal extent or not (7) . The longevity of a tooth depends on its periodontal health.…”

The Effect of Using a Modified Dentoalveolar Distractor on Canine Angulation following Rapid Canine Retraction: A Split-mouth Design Randomized Controlled Trial

“…9 The distal displacement of the canines was always accompanied with different degrees of distal tipping that ranged from 7.11 to 13.15°. [9][10][11][12][13][14] Therefore, the distal displacement of the canines was mainly a combination of tipping and translation.…”
