Fixed Tongue Loops may be used to control the effects of tongue thrusting or to prevent a patient from thumb sucking. This interference is often enough to allow the facial muscles to act upon the anteriors and return them to their normal position. Myofunctional therapy is initiated by adding a spinner. If more aggressive treatment is needed, simply cut off the apex of the loops and straighten the wires to create a modified Hay Rake.

Note: An opposing model and bite relationship are required with all habit appliances.
