ABSTRACT
INTRODUCTION:
This study aimed to investigate the effect of root dilaceration on the closed-eruption technique treatment and prognosis on impacted immature maxillary central incisors.METHODS:
In this retrospective study, we compared the age at the beginning of the treatment, the treatment duration, root development, and alveolar bone mass after the closed-eruption technique between the impacted immature maxillary central incisors with dilacerated roots (group 1) and those with straight roots (group 2).RESULTS:
The mean age at the time of the surgery of group 1 was 0.9 years younger than that of group 2 (P = 0.008). The mean traction time was greater in group 1 (8.0 ± 1.8 months), with a difference of 1.4 months than in group 2 (6.6 ± 2.1 months) (P = 0.042). The measurements of lingual bone thickness at the alveolar crest (C) showed significant differences between the 2 groups (P = 0.025). No significant differences were found in other treatment duration or measurements of root development and alveolar bone mass between the 2 groups.CONCLUSIONS:
Patients with impacted immature incisors with dilacerated roots were younger at the beginning of the closed-eruption treatment and had a longer traction time than those with impacted immature incisors having straight roots. The root dilaceration had little or no effect on root development and alveolar bone mass after the closed-eruption treatment. The closed-eruption treatment of impacted immature incisors with root dilaceration is suggested to commence as early as possible.
