Mechanical Strength Variety of Orthodontic Polymeric Chains In vitro assessment and mathematical model

Abstract

Elastomeric chains, as means of force delivery, are one of the most studied elements of the orthodontic field. Effects on tooth movement are closely related to force degradation degrees of these polymers. Unfortunately, due to varied manufacturing techniques and materials, different brands of elastomeric chains offer different initial force values and different force decay, with direct impact on tooth movement duration and effectiveness and quality of orthodontic treatments.
