a: A seven-year-old patient with complete eruption of both lateral incisors and left central incisor. b: Panoramic X-ray image of tooth 11 positioned horizontally with apparent root angulation. c: Cephalometric X-ray image of the crown of tooth 11 is inclined in cranial direction. d: Cone-beam computed tomography sagittal view showing root dilaceration is evident. e: Lifting the mucoperiosteal flap and exposing the palatal surface of the crown of tooth 11 prior to bonding of the attachment. f: Cephalometric X-ray image showing the attachment on the palatal surface and chain traction in the palatal direction toward the extension arm of the palatal arch. g: Impacted right central incisor aligned into the dental arch. Attached gingiva is apparent due to the eruption of the tooth through the alveolar ridge crest. The crown torque is insufficient. h: Ideal gingival margins and equal amount of attached gingiva on teeth 11 and 21 at debonding. i: Ideal crown torque of tooth 11 from the occlusal view after debonding. j: Panoramic X-ray after treatment demonstrating the same root lengths on teeth 11 and 21
