Effective Torque Correction for Buccally Erupted Ectopic Canines.

This article discusses a custom-made spring appliance that can correct excessive root torque in cases with buccally erupted ectopic canines. It provides case studies and demonstrates the successful repositioning of ectopic canines using the appliance. The treatment involves the use of torquing auxiliary springs and sectional wires to correct the torque and alignment of the canines. The authors emphasize the importance of well-planned biomechanics in achieving successful tooth movements and avoiding complications. The article provides detailed descriptions of the treatment procedures and includes radiographs and images to illustrate the cases. [Extracted from the article]
