Orthodontic mechano treatment of ectopic eruption of the permanent mandibular incisors of Iraqi children (early mixed dentition)‎ : a longitudinal clinical study

Abstract EN

Fixed orthodontic appliances used to treat cases of bilateral distal ectopic eruption of the permanent mandibular central incisors.

A total of 27 Iraqi children at average age of 7.5-years old selected for the study.

15 patients (9 females and 6 males) treated by extraction of the retained primary teeth and placement of fixed appliances for alignment and repositioning of the mandibular permanent incisors.

while 7 patients (3 females and 4 males) treated by extraction of the corresponding retained primary tooth and later alignment of the mandibular incisors, and 5 patients (2 females and 3 males) treated by extraction of the relevant permanent lateral incisors and the corresponding retained primary teeth.

The result of present study showed significant difference between the first method of early mechanical orthodontic and another two methods of later mechanical orthodontic treatment regarding time consuming, esthetic and complexity factors.

No significant differences clinically between gender groups and sides in the jaw.

clinically the first method was easier and faster if compared with other methods of later orthodontic mechanical which may need a serial extraction, expansion or other orthodontic intervention that increase the complexity of cases treatment.
