Speed of Premolar Extraction Space Closure: Healed vs Recent Extraction Site

Jordan University of Science and Technology28 enrolled

Overview

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

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.
