The first method is useful when
the canine has a correct axial inclination
and needs no upright correction
during its eruption, but this method
may increase treatment time and be
unable to control the path of eruption.
2 Kokich47 suggested performing
this method before the beginning of
orthodontic treatment or during the
late mixed dentition because the
tooth will erupt in a more favorable
location, which will facilitate orthodontic
movement without dragging
the crown through the palatal gingiva.
Schmidt and Kokich48 also reported
that this technique had minimal
effects on the periodontium and that
the overall effects on the impacted
canine appeared better than those
from the closed exposure and early
traction techniques.
