Abstract
ABSTRACTObjective: The aim of this study was to evaluate the movement of impacted canines away from the roots of neighboring teeth before full-mouth bracket placement, performed by means of TADs to decrease undesired side effects on adjacent teeth. Methods: The study sample consisted of 34 palatally impacted canines, being 19 in the experimental group and 15 in the control group. In the experimental group, before placement of brackets, the impacted canine was erupted by means of miniscrews. In the control group, after initiation of comprehensive orthodontics, canine disimpaction was performed by means of a cantilever spring soldered to a palatal bar. At the end of treatment, volume of lateral incisors and canine root resorption were measured and compared by means of a CBCT-derived tridimensional model. Visual Analogue Scale (VAS) score, bleeding on probing (BOP) and gingival index (GI) were recorded. Clinical success rate was also calculated. Results: The volume of root resorption of lateral teeth in the control group was significantly greater than in the experimental group (p < 0.001). At the end of treatment, VAS score, GI and BOP were not significantly different between the two groups. Conclusion: Based on our results, it seems that disimpaction of canines and moving them to the arch can be done successfully carried out with minimal side effects by means of skeletal anchorage.
Highlights
Impaction of maxillary permanent canines is a common clinical problem in the dental office.[1]
A total of 26 patients (15 in the experimental group and 11 in the control group) with 34 palatally impacted canines participated in this study
The experimental group consisted of 19 palatally impacted canines while the control group consisted of 15 palatally impacted canines
Summary
Impaction of maxillary permanent canines is a common clinical problem in the dental office.[1] Ericson and Kurol[2] reported that the incidence of maxillary canine impaction is 1.7%.2. It is estimated that the incidence of palatal impaction is two or three times greater than labial impaction.[3] Maxillary canines play an important aesthetic and functional role; in this regard, treatment is essential; impacted canines are more difficult and time-consuming to treat. Diagnosis of canine impaction is based on clinical and radiographic evaluations.[5] Assessing the condition of the lateral incisor root is crucial, since in 80% of cases the roots resorbed by impacted canines were those of lateral incisors.[4]
