•We reported on the level of risk of failure in the treatment of impacted central incisors.•We reported on the importance of the etiology as the principal factor influencing the prognosis.•We reported on the duration of treatment of impacted central incisors.•We determined the main factors that increase the treatment time.
IntroductionIn this study, we aimed to assess the patient and treatment factors that influence the success rate and the duration of the orthodontic-surgical modality for impacted central incisors.MethodsThe records of 60 consecutively treated patients (64 impacted incisors) were retrospectively evaluated. The success rate and the duration of each stage of treatment were examined in relation to age, sex, etiology of impaction, location of the impacted tooth, and type of surgical exposure performed. Logistic regression analyses were applied.ResultsThe group consisted of 26 male and 34 female subjects, 7.0 to 21.9 years old; 27 patients had impactions because of root dilaceration, 29 had impactions because of obstruction, and 4 had impactions with unknown causes. The overall success rate was 90.0%. Five of the 6 failures were dilacerated incisors. The average duration of treatment was 21.6 ± 8.7 months. The only factor that significantly increased the duration was the height of the impacted tooth. Dilaceration was related to a longer stage of traction and, in older patients (late mixed and full permanent dentition), to a longer finishing stage.ConclusionsThe orthodontic-surgical treatment of impacted incisors is generally successful, but relatively long. Patients and parents should be warned of the risk of failure and the increased treatment duration, especially for dilacerated incisors impacted high in the alveolus.
