Orthodontic height positioning gauge with rotatable heads

Abstract

An orthodontic height hand gauge is both double-ended and double-sided, allowing four measurement heights to be determined by a single tool. Each end of the gauge has a rotatable element capable of rotating and stopping at zero degrees, 45 degrees, and 90 degrees from the handle axis by a plunger mechanism which provides a detent function. Rotatable ends provide proper gauge alignment to the tooth, especially for difficult-to-reach teeth in the back of the mouth. A center tab extends longitudinally from each rotatable element and is separated by a given distance from top and bottom legs which extend parallel to the center tab. The distances between the center tab and the legs are two different gauge heights to be measured. Thus, by using both ends of the tool, four gauge distances can be measured.
