Study type | Interventional |
This experimental study will evaluate the effect of corticision on accelerating the leveling
and alignment of lower crowded incisors compared with the control untreated group using cone
beam computed tomography.
The study sample will consist of 26 patients with less than 6 mm crowding. The sample will be
allocated randomly into two experimental groups.
The brackets and passive SS wire will be applied with radiographic metal guides between each
tooth to allow for accurate corticision site 2 mm below the gingival papilla and to prevent
tooth roots injury. The dentoalveolar changes occurring after leveling and alignment of lower
anterior teeth will be evaluated using CBCT radiographs, Frequency, degree of root
resorption, and the incidence of bone dehiscence will be assessed in relation to initial
situation.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Speed of lower teeth movement. | The speed of lower teeth movement during leveling and alignment stage will be measured and compared between groups. | After the leveling and alignment stage of the lower teeth, which will take approximately 9 months | |
Secondary | Changes of lower teeth torque | The torque changes of the lower teeth will be evaluated and compared between the 2 groups using CBCT. | Changes will be evaluated before and after the lower teeth leveling and alignment stage, which will take approximately 8 months | |
Secondary | Changes of lower teeth tipping | The tipping changes of the lower teeth will be evaluated and compared between the 2 groups using CBCT. | Changes will be evaluated before and after the lower teeth leveling and alignment stage, which will take approximately 8 months |
