Spontaneous improvement in position of canines from apparently hopeless positions

Two cases are presented, each with both unerupted maxillary canines so badly positioned that eruption seemed unlikely. However, over a period of approximately three years, three out of the four initially displaced canines did erupt; the improvements in position being unrelated to whether or not the associated primary canine was extracted. Three out of four primary canines were removed. These cases highlight the difficulties in predicting canine eruption for individual patients.
