A short review on force degradation in elastic/elastomeric chains in orthodontic appliances

For some decades elastics have been a valuable adjunct of any orthodontic treatment. Synthetic elastomers overcome various limitations of natural rubber. The use of elastics in clinical practice is predicted on force extension values given by the manufacturer for different sizes of elastics. Elastics can be used in various configurations for correction of a particular malocclusion. It is very important for the orthodontist to educate the patient regarding the correct use of elastics as treatment results are dependent on patient cooperation. This article strives to summarize the currently available data on the various aspects of elastics including their properties, clinical usage and limitations.
