Turning The Key on your Airway Appliance

Step by step instructions on how to turn the key and expand your upper or lower airway appliances

Expanding Your Upper Tanner Airway Appliance

  • Hold the appliance so the smooth side is up towards the ceiling, tooth side down towards the floor.

  • Look for the faint arrows pointing down towards the floor (this is the direction you will be turning the key)

  • Hold appliance under the screw your about to turn *this will insure you don’t put too much pressure and break or crack appliance. Insert key in the small hole Located in the gap between the smooth surface of appliance.

  • Turn the key down towards the floor about 90 degrees. This is one full key turn.

  • When the key head is facing down and has been turned as far as it will allow (about 90 degrees), you are done! Pull out key and repeat the same process on the other side.

Lower Schwartz Appliance

  • Hold the appliance, bracing sides to ensure it does not bend or break. Insert key into the top hole.

  • Push down 90 degrees in the direction of the arrows. Pull Key straight out and you are done. This is one full turn.

Lower Richardson

  • When the appliance has become passive and is no longer putting lite pressure or is loose in the mouth you will expand (every 1-2 weeks)

  • Hold the acrylic arms of the appliance and pull apart lightly, when appliance is places back in the mouth it should feel snug with lite pressure, not painful.
