How Does It Work?
Measure the distance between the center of the eye and the commissure of the lips using the two straight, extended markers.
Tighten the bolt to lock that measurement into place.
Using the other side of the gauge, place the friendly rounded edge just under the nose and under the chin. If the the curved, chin marker fits snugly under the chin, you have accurately captured the patient’s VDO.
If the curved, chin marker is not in contact with the chin, then the patient is over-closed.
If the curved, chin marker is short of the chin, the patient is too open.
Note that the gauge was never intended to replace a doctor’s knowledge and experience – it is a tool to be used to help find a patients VDO quickly, consistently, and accurately, but any measurement should be verified through removable techniques to ensure a positive case outcome.
