Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • The Little's Index

    The Little's Index of Displacement score will be the primary clinical endpoint used to judge patient success (i.e., effectiveness).

    Movement will be recorded by capturing the start and end point of the 6 anterior teeth before and at the completion of the treatment respectively. The duration of the treatment will be up to 10 months.

Study Arms (1)

Tooth positioner treatment group

EXPERIMENTAL

The participants that meet the inclusion criteria will be treated with tooth positioner.

Procedure: Tooth positioner

Interventions

Orthodontic Tooth positioners treatment have been used in the Orthodontic Industry for many years. These positioners are used for small minor movements to complete the final smile. These positioners are made from a biocompatible and FDA approved clear silicone material after the teeth have been set to the final position.
