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

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.
