Fig. 4From: Effect of filament types and loops number on the force degradation of elastomeric chains used for orthodontic treatment: an in-vitro studyForce decay curves of the elastomeric chains have four loops and different connectors. A1B1, close elastomeric chains with 4 loops. A2B1, medium elastomeric chains with 4 loops. A3B1, long elastomeric chains with 4 loopsBack to article page
