Acceleration of Lower Anterior Teeth Leveling and Alignment Using Corticision

NCT03310086 | Completed DMC

• 1 other identifier: UDDS-Ortho-07-2017
• Study Type: interventional

Brief Summary

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.

Conditions

Crowding, Tooth

Keywords

corticision; CBCT; Crowding

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (2)

• Changes of lower teeth torque

  Changes will be evaluated before and after the lower teeth leveling and alignment stage, which will take approximately 8 months

• Changes of lower teeth tipping

  Changes will be evaluated before and after the lower teeth leveling and alignment stage, which will take approximately 8 months
