The construction bite registration should hold the mandible in the most protruded unstrained position. Although you can take this bite with the traditional freehand method, Airway Management & Accutech recommend using the George Gauge for best results. The George Gauge offers a simpler, more accurate method. You can be assured of a correct registration by presetting the gauge for the desired bite. You then have the patient simply bite simultaneously into the incisor notches and registration material. The George Gauge is an adjustable instrument that can be preset to guide the mandible to any desired position along the range of the protrusive path. It also serves as a vehicle for the registration material.
The gauge consists of three parts: the lower incisor clamp, the bite fork, and the body. The lower incisor clamp slides in and out of the body, forming the lingual wall of the lower incisor notch. It can also be adjusted to fit over rotated incisors. The bite fork, which also slides in and out, contains the perforated prongs that hold the registration material, the upper incisor notch, and the shaft whose anterior end indicates mandibular position on the millimeter scale of the body. Bite forks are available in two incisor notch sizes, one producing a 2mm inter incisal distance (Not recommended for the TAP) and the other being 5mm which is the best for a TAP. PLEASE NOTE: Even if you do not use the George Gauge, the TAP requires at least a 5mm anterior opening to allow adequate room for the hardware and plastic.
