Summary

This clinical study used CBCT images to investigate the alveolar bone changes and root resorption in unilateral buccally displaced maxillary canines and adjacent teeth before and after orthodontic traction of unilateral BDMCs.

The CBCT images will also be used to compare these changes to the normal contralateral side. The study outcome is to compare the 3-D changes in the alveolar bone and dental roots between the 2 interventional techniques (segmentalT-loop and piggyback NiTi traction) methods.

Conditions

  • Malocclusion; Displaced Teeth

Interventions

DEVICE

T-loop

Firstly, only the BDMC will be bonded with a preadjusted edgewise bracket from the 0.022-in-slot MBT system and cementing the trans palatal arch. Canine traction will be carried out by ligating the segmental T loop of 0.016×0.022 TMA wire on the BDMC and inserting the other end of the T loop in the maxillary first permanent molar tube. The segmented T loop will be activated by 2 mm per month and tightened posteriorly to the tube of the first permanent molar for approximately 3 months to move the canine. Once the BDMC is in the proper site in the maxillary arch, all teeth in both maxillary and mandibular arches will be bonded with preadjusted edgewise brackets from the 0.022-in-slot MBT system. Leveling and alignment will start with engaging 0.014-in NiTi arch wires in both arches.

DEVICE

Piggyback double wire

All teeth in both maxillary and mandibular arches will be bonded with preadjusted edgewise brackets from the 0.022- in-slot MBT system. Leveling and alignment will start with engaging 0.014-in NiTi arch wires in both arches, bypassing maxillary BDMC. The arch wire sequence will include 0.014-in NiTi, 0.016-inch NiTi, 0.016x0.022-inch NiTi. After the arches are properly aligned, the piggyback technique will be used on the maxillary arch, and the arch wire size will be increased to 0.016 x 0.016-inch stainless15 steel for the maxillary arch and ligating the accessory 0.012-inch NiTi round for BDMC traction.
