PURPOSE: To assess the effect of removable and fixed orthodontic device in restoring teeth space loss in children.
METHODS: Removable or fixed orthodontic device was used randomly to restore teeth space loss in 25 children, the advantages and disadvantages between the two methods were compared. SPSS 22 software package was used for data analysis.
RESULTS: Among 25 cases, 2 had deciduous dentition and 23 had mixed dentition, removable and fixed orthodontic device was used in 13 and 12 cases, respectively. Finally 18 cases achieved success, 3 cases were improved and 4 were failed. Fisher's exact test was used to compare the success rates of active and local fixed appliance to enlarge interdental space. The success cases of active and fixed appliance were 9， respectively. There was no significant difference between the two methods (P=0.68). Within these cases, the fastest restoring time was 3 months and the slowest restoring time was 11 months.
CONCLUSIONS: It is an ideal method to restore teeth space with removable or fixed orthodontic device. It is a simple, fast and economic method for early orthodontic treatment for children.
