case_images: The cephalometric evaluation highlighted a brachyfacial typology with a sagittal skeletal relationship of Class I (Figure 2). The panoramic radiograph showed the germs of wisdom teeth of both dental arches (Figure 2).
case_images: CT scan showing the axial (a) and the sagittal ((b), (c)) view of the maxillary impacted canine and the axial and frontal view of the mandibular canine ((d), (e), (f)).

case_images: A palatal impaction of the maxillary right canine, the ectopic eruption of the maxillary left canine, and the impaction of the mandibular left canine due to a small odontoma were visible in the CT scan (Figure 3).

case_images: A cantilever modelled using .019'' x .025'' TMA. Initially, a first order:offset (a) and a second order (b) bends are modelled close to the maxillary molar to avoid interferences with premolar brackets and to activate the cantilever. Then, a first order bend (c) directed palatally is used to anchor the canine.

case_images: TMA wire (Ormco, Orange, CA, USA, Figure 4). TMA is an elastic titanium molybdenum alloy showing Young's modulus of about 100 GPa.
case_images: Cantilever activated for obtaining extrusion by a third order bend (a) and a second order bend (b). Cantilevers in position (c).

case_images: The extrusion of the maxillary right canine was obtained by inserting a third order bend (read as a buccal root torque of the molar) at the insertion of the maxillary molar (Figures 5(a) and 5(c)). For the maxillary left canine the cantilever was activated in extrusion by a second order bend (Figures 5(b) and 5(c)), which determined a caudal displacement of the hook. A second order bend was modelled close to the molar for obtaining extrusion (Figure 5).
case_images: From left to right, progressive recovery of the maxillary canines.
