The orthopantomogram radiographs (OPGs) were analyzed for palatally impacted canine angle and horizontal and vertical position. Recovery time was measured from the start of forced eruption until the canine was within \u00b11 mm of final dental arch position.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n The time of forced canine eruption with ostectomy-decortication technique was significantly shorter than without (6.6 vs 21.0 months). Pretreatment canine position significantly increased forced-eruption time in the ostectomy-decortication group but not in the control sample.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Forced-eruption time of palatally impacted canines using the ostectomy-decortication technique was 3.2 times more rapid than without.
