Elastics

This section on elastic wear was compiled because so many clinicians wanted more informationon how elastics were being worn in a passive self-ligating environment. We all know there aremany different ways to achieve clinical results. An attempt has been made to keep treatmentmechanics very simple. The following represents the elastics used on a daily basis in the clinic.It is exciting to see what can be achieved with elastic wear if the mechanical system is not boundup and if the forces used are biologically sensible.

Philosophy for Elastics

Use posts on archwires to distribute force evenly over all teeth. Gentle force is respectful of tissue. Eliminating bracket hooks keeps appliance clean and promotes healthy tissue.

Remember the tie-wings are free to receive elastics.
