Abstract :
Context One of the most important aims in orthodontic treatment is
to apply a light continuous force to achieve maximum effective tooth
movement with minimal side effects (optimal tooth movement). It is
obvious that elastomeric chains are the most popular method of space
closure, but they undergo force decay during time. Force decay behavior
of elastomeric chains is influenced by various factors. It is crucial
for every practitioner to know about these products and factors
affecting them. Evidence Acquisition So we searched English articles
published in Pubmed between 2005 - 2016 with keyword “orthodontics,
elastomeric chain”. Results 25 articles were selected for comprehensive
reading according to the inclusion criteria. Some factors such as aging
process, production technique, pre-stretching effect, design and type of
chains, in-vivo effects and microbial contamination were discussed.
Conclusions By reviewing these articles, we know more about force decay
pattern of elastomeric chains. Most of articles said the same force
decay pattern for these elastomeric products. We know more about
environmental conditions affect their features. This can help
practitioners to use chains , in a better way.
