N/AWithdrawnNCT03332082

University of Alabama at Birmingham

Overview

Orthodontic relapse occurs in almost 80% of Orthodontic Treatment. The only prevention to phenomenon is the use of fixed retainers or life time active retention. Unfortunately, patients do not comply and after a year of treatment, many stop wearing their retainers and Orthodontic relapse occurs. The aim of this project is to prospectively analyze the treatment result of consecutive treated patients who have had active orthodontic relapse. 20 patients will be recruited through advertisement to the Department of Orthodontics at the University of Alabama at Birmingham (UAB). The sample will comprise of 20 patients with Class I malocclusions. The records to be collected will comprise of clinical pictures and pre and post study casts. The 3D study casts will be evaluated using the Little's Index. The results will be analyzed with the paired t-test and ANOVA, using the Statistical Analysis System (SAS/STAT®) software.
