Force decay of orthodontic elastomeric chains: A systematic review

In orthodontic therapy elastics and elastomeric chains are commonly used as an active component. These synthetic elastic materials not supposed to be ideal, they sensitive prolonged exposure saliva, water, enzymes, temperature variations external factors. The main disadvantage of auxiliaries is their inability sustain the delivered force for extended period time. objective this review determine time taken by degrade after stretching assess oral environment factors affect decay chains. Databases such PubMed, Medline, Cochrane Library searched electronically. Additional sources (Google Scholar, clinicaltrails.gov) were manually additional trials or protocols until December 2021 Studies involving in vitro vivo various like, temperature, beverages, food, paste, mouthwash, etc included. 18 studies included primarily focused on E-chains also associated Elastomeric was affected time, environment. greatest effect chain shown temperature. Force loss increased with increasing expected a viscoelastic material.
