Model 8645 "QUICKMOUNT" FACE-BOWS provide a convenient, quick and accurate method of securing an axis location without the use of expensive equipment and time-consuming techniques. Employing as the three reference points, the two external auditory meatus of the ears and the bridge of the nose, no measurements or markings on the patient are needed. The self-centering caliper design is easily adjusted, and the nasion relator utilizes the bridge of the nose to obtain an accurate and reproducible anterior reference. The MODEL 8645 FACE-BOW is compatible with all Whip Mix Articulators, and allows for the recording of an approximate intercondylar distance. The MODEL 8645 utilizes "T" screws that are tightened by hand, which are a convenient and time-saving feature.
