Orthodontic elastomeric chains' force deterioration – A REVIEW

Abstract

Many orthodontic methods employ elastomeric chains to provide force, however as time passes, this force deteriorates and may impact tooth mobility. The force degradation of elastomeric chains was the focus of this investigation. Elastomeric chain force breakdown is significantly influenced by salivary enzymes, alcohol-containing mouthwash, whitening mouthwash, tooth movement, and alkaline and very acidic (pH <5.4) solutions. Elastomeric chains' force level diminishes quickly over time, whereas thermoset chains' force degradation rate is slower than thermoplastic chains'. The use of a thermoset chain type with monthly replacement might result in an effective tooth movement. To reduce the possibility of cytotoxicity, ethylene oxide and gamma sterilization techniques are recommended.
