Dental study tests which elastic works best for tooth movement
NCT ID NCT07141836
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study compared two methods—elastic chains and elastics—for moving canine teeth backward after premolar extraction. Thirty-three orthodontic patients participated, and researchers measured how fast and how straight the teeth moved. The goal was to find a more effective way to control tooth movement during braces treatment.

Inclusion Criteria: * Patients' treatment required 1st premolar extractions in the maxillary arch and space closure involving canine retraction. * Teeth in the buccal segments were without any gross anatomic root anomalies as determined by panoramic radiographs. * There is no gross evidence of asymmetric bone loss in the buccal segments of a given arch as determined by panoramic radiographs. * Crown/root ratios of contralateral canines and premolars are within 3 mm of one another as determined by panoramic radiographs. Exclusion Criteria: * Patients with gross anatomical anomalies in upper maxillary canines * Patients with growth and development problems. * Evidence of bone loss. * Presence of Impacted Canine. * History of long-term use of NSAIDs and corticosteroids or drugs affect bone metabolism. Patients who reported any medication interfering with bone metabolism or patients with severe skeletal discrepancies indicated for orthognathic treatment. * Patients with latex materials allergy.
