Abstract:
Background

Canine teeth have a significant impact on the order and proper function of other teeth. Canine impaction can have negative esthetic and functional effects. This study investigated the success rate of orthodontically-assisted eruption of maxillary canine teeth according to age, sex, and type of impaction in Shahrekord city, Iran.

Methods

In this retrospective study, panoramic radiographs of 112 patients who had initiated their orthodontic treatment at least 2 years earlier and had completed it by 2023 were evaluated. Cone-beam computed tomography scans were also used when necessary to assess the details. The type, depth, and angle of erupted and impacted canine teeth were determined. The data were analyzed by the Fisher's exact test and t-test.

Results

Impacted canines successfully erupted in 72 patients (64.3%). Palatal impaction was more common (71.4%) than buccal impaction (28.6%). Regarding the impaction depth, type C had the highest frequency (63.4%), followed by type B (30.4%), and type A (6.3%). There was no significant correlation between the gender of patients and success rate of assisted eruption (P>0.05), but age and type of impaction were correlated with the success rate (P<0.05). The erupted canine teeth had a significantly higher mean angle relative to the occlusal plane compared with non-erupted teeth (P<0.05).

Conclusion

The success rate of orthodontically-assisted eruption of impacted maxillary canine teeth was high, and patients in the age range of 15 to 18 years with grade II impaction showed the highest success rate of orthodontically-assisted eruption of impacted canine teeth.
