Clinical Trial Summary

The aim was to compare the rate of teeth movement into fresh and old extraction sites.

Description:

Trial design: Randomized controlled clinical trial with a split mouth design. Setting: Jordan University of Science and Technology(JUST) Postgraduate Dental Teaching Clinics and labs. Participants and interventions: Twenty-eight subjects with bimaxillary proclination requiring extraction of all first premolar teeth participated in this study. In the lower arch, two groups were also identified; group 1 having the first premolar extracted before the commencement of orthodontic treatment and group 2 having the first premolar extracted just before space closure when 0.019 x 0.025 inch SS archwire was reached. Patients were followed-up monthly for three months. At every follow-up visit lower alginate impressions were taken. Extraction spaces in the lower arch follow-up models were measured using digital caliper. The rate of extraction space closure in the lower arch was assessed monthly.
