A revolutionary expansion device

One full turn of the key delivers 0.2mm of expansion. For an apprehensive patient, half-turn activations for the first few days build confidence — the increment is entirely up to the doctor.

The activation screw-head is easy to see, and the ball-ended key seats even when it's off-axis by up to 20 degrees. A target symbol shows which way to turn — like turning a car key.

A simpler appliance means less instruction. Chair-side teaching time drops and re-instruction appointments largely disappear, making the VECS™ cost less in practice than a traditional expander.

Accidental swallowing or aspiration of an activation key is a life-threatening risk the literature has warned about for decades. The VECS™ key is large and handled entirely outside the mouth.
