NCT05350280

Brief Summary

Thirty-eight patients requiring extraction of maxillary first premolars and maximum anchorage to retract the upper anterior teeth will participate in the study. They will be divided randomly into two groups: electrical group and control group. In each group, en-masse retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 250 g of force per side, Mini-implants will be used as an anchor unit. The dental changes will be detected using dental casts and to evaluate the rate of teeth retraction.

Outcome Measures

Primary Outcomes (2)

  • Rate of retraction

    Assessment will be performed on study models. The amount of distance being retracted in millimeters will be divided by the duration of retraction in weeks to give an estimation of the retraction rate.

    The calculation of the rate of retraction will be done once the retraction procedures has finished. Completion of this procedure is expected to occur within 6 months in the experimental group and 8 months in the control group.

  • Change in Incisors' positions

    Amount of distance being traveled by the retracted anterior teeth is going to be measured on study models taken at monthly intervals until the end of the retraction phase.

    T0: 1 day before the beginning of retraction. T1: after 1 month (m) of retraction. T2: after 2 m of retraction. T3: after 3 m. T4: after 4 m. T5: at the end of retraction (expected to be within 6 m in the exp. group and 8 m in the control group)

Secondary Outcomes (3)

  • Change in Molars' positions

    T0: 1 day before the beginning of retraction. T1: after 1 month (m) of retraction. T2: after 2 m of retraction. T3: after 3 m. T4: after 4 m. T5: at the end of retraction (expected to be within 6 m in the exp. group and 8 m in the control group)

  • Change in the inter-canine width

    T0: 1 day before the beginning of retraction. T1: after 1 month (m) of retraction. T2: after 2 m of retraction. T3: after 3 m. T4: after 4 m. T5: at the end of retraction (expected to be within 6 m in the exp. group and 8 m in the control group)

  • Change in the inter-molar width

    T0: 1 day before the beginning of retraction. T1: after 1 month (m) of retraction. T2: after 2 m of retraction. T3: after 3 m. T4: after 4 m. T5: at the end of retraction (expected to be within 6 m in the exp. group and 8 m in the control group)

Study Arms (2)

Low-intensity electrical current (LIEC)

EXPERIMENTAL

A removable device containing a small electrical circuit will supply the required electric current for five hours a day until the completion the retraction of the upper anterior teeth.

Device: electric current

Traditional fixed orthodontic appliance

ACTIVE COMPARATOR

The maxillary arch will be levelled and aligned. (250-300) g force will be applied on each side using two NiTi springs attached between the mini-implants and the soldered hooks in a direction approximately parallel to the occlusal plane for conducting an en-masse retraction.

Device: Traditional treatment

Interventions

Electric current will be applied in this group of patients using removable device.

Low-intensity electrical current (LIEC)

No acceleration method will be performed in this group.

Traditional fixed orthodontic appliance

Eligibility Criteria

Age16 Years - 25 Years
