Summary

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

Detailed 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.

Conditions

• Orthodontic Appliance

Interventions

Type	Name	Description
DEVICE	Space closure into old extraction space	Lower first premolar extraction space was closed using elastic power chain and 0.019X0.025 Stainless steel archwire into healed bony socket
DEVICE	Space closure into recent extraction space	Lower first premolar extraction space was closed using elastic power chain and 0.019X0.025 Stainless steel archwire into fresh bony socket
