Comparison Between Lingual and Labial Fixed Orthodontic Appliances in the Treatment of Crowding Cases

NCT03850951 | Completed DMC

• 1 other identifier: UDDS-Ortho-04-2018
• Study Type: interventional
• Target: 44
• Locations: 1 country
• Sites: 1

Brief Summary

Patients who have moderate crowding that could be treated without extraction will be treated in this study using either lingual or labial fixed orthodontic appliances. All patients will receive a cone-beam computed tomography (CBCT) scan in two different times (T0: before treatment, T1: after treatment). The dentoalveolar changes will be assessed.

Conditions

Crowding

Keywords

Fixed appliances; labial appliances; lingual appliances

Outcome Measures

Primary Outcomes (1)

• Dentoalveolar changes after crowding treatment

  Dentoalveolar changes before and after crowding treatment will be evaluated using CBCT.

  Changes will be evaluated before and after crowding treatment which will take approximately 12 months

Secondary Outcomes (2)

• ABO- Objective Grading System

  After treatment completion, an average of 1 year

• Change in oral health related quality of life

  (1) at the beginning of the treatment, (2) after week, (3) after 2 weeks, (4) after 4 weeks, (5) after 6 months, (6) after treatment completion, an average of 1 year.
