Intraoral examination revealed proclined incisors, class I molar relationship on both sides, and missing left maxillary canine [Figure 1a and b]. Orthopantomograph (OPG) unveiled impacted left maxillary canine [Figure 1c]. One end of the cantilever spring was inserted into the accessory tube and another end was tied with ligature wire on lingual button Figure [1d and e]. Figure 1f and g shows an intraoral view and Figure 1h shows OPG after alignment of left maxillary canine.

Intraoral examination revealed missing left maxillary canine and lower right mandibular first molar with class I molar relationship on the left side and deep bite [Figure 2a and b]. A flap surgery was performed to expose palatally impacted canine 23 and lingual button was bonded overexposed surface [Figure 2d]. Other end of this spring was tied with ligature wire on lingual button [Figure 2e]. After 1 month, the canine was erupted in the oral cavity [Figure 2f]. Fixed anterior bite plate was cemented and orthodontic traction was carried using active tie back from canine bracket to main archwire [Figure 2g]. Figure 2h and i shows maxillary occlusal view and OPG, respectively, after alignment of left maxillary canine.

Intraoral examination shows the presence of bilateral deciduous maxillary canine on both sides with anterior crossbite involving both maxillary central incisors and maxillary right lateral incisor and deciduous canine [Figure 3a and b]. Lingual button was bonded and ligature tie was given from button to main archwire [Figure 3d and e]. Elastic was given from the lingual button to the right mandibular canine for buccal and caudal eruption of right maxillary canine [Figure 3f]. The aligned right maxillary canine is shown in Figure 3g and h along with OPG in Figure 3i.

Intraoral examination shows the presence of bilateral retained deciduous maxillary canine [Figure 4a and b]. Lingual button was bonded on both canines [Figure 4d]. Then, the spring was activated by passing ligature tie through helix of vertical loop of spring and tying another end to lingual button bonded over impacted canine [Figure 4e and f]. Figure 4g and h represents intraoral view and Figure 4i displays OPG after alignment of left maxillary canine.

A bulge is present palatally in the left lateral incisor region [Figure 5a and b]. Modified ballista spring was used to provide extrusive force to impacted canine, with 0.019'' x 0.025'' SS base archwire in maxillary arch [Figure 5d and e]. Maxillary occlusion and left buccal occlusion view after alignment of left maxillary canine is shown in Figure 5f and g correspondingly with OPG in Figure 5h.
