Treatment Record:
SPEED brackets were bonded to upper and lower 6-6. Composite was bonded to the occlusal surface of each of the lower first molars to open the bite and prevent interference between the upper incisors and lower anterior SPEED brackets.
Maxillary Arch:
Initial alignment was achieved with .014 Light Force Heat Activated Nickel Titanium, followed by round .018 Stainless Steel with open coil spring to open space for the upper left canine. Closed coil was then inserted to hold space for the upper left canine, pending surgical exposure. Following surgical exposure, the canine was bonded and .014 Nickel Titanium was used for alignment. A .018 x .025 Stainless Steel wire was used for archform coordination, followed by .021 x .025 Stainless Steel for full expression of appliance prescription and final arch form.
Mandibular Arch:
Light force heat activated wires were used for initial alignment of centrals and posterior teeth, bypassing the ectopic lower lateral incisors. As alignment resolved, open coil springs were used to close the space distal to the first premolar and correct lingual inclination of the lower central incisors. Arch form was initiated with .018 x .025 Stainless Steel while coil springs were continued to maintain space. Lower lateral brackets were then bonded and engaged via a .014 Nickel Titanium segmental wire running from 34 to 44 through the SPEED auxiliary slot. Further activations of lower laterals were achieved using .016 Nickel Titanium and .018 Stainless Steel, while open coil springs were continued to open space for the lower canines. Following surgical exposure of the lower right canine, both canines were bonded and engaged using first a .014 Nickel Titanium and then a .014 x .025 Nickel Titanium wire. Torque expression was achieved via .018 x .025 followed by .021 x .025 Nickel Titanium. Final torque expression was achieved with .021 x .025 Stainless Steel with Class II elastics to obtain Class I occlusion. |
