What is it about?

The aim of this study was to investigate the orthodontic force exerted by thermoplastic orthodontic appliances incorporating Eucommia ulmoides in terms of usefulness as the aligner-type orthodontic device.

Why is it important?

Eucommia elastomer (EE), a trans-1,4-polyisoprene extracted and purified from Eucommia ulmoides, is a highly biosafety polymer exhibiting high tensile properties and large breaking strain. As a tensile property, it shows high stress to initial strain, but after that it shows constant stress even if strain increases. Therefore, it can be expected that an aligner made from EE is suitable for tooth movement and be able to exert a constant orthodontic force.

Perspectives

Eucommia elastomer has possibly become one of the more useful materials to form thermoplastic orthodontic appliance exerting low continues orthodontic force.
