The SlidematicFacebow provides a fast, easy andextremely accurate means of transferringthe proper anatomical relationship to thearticulator. Any Denar ® facebow may beused for mounting the maxillary cast tothe Track <strong>II</strong>. In this chapter only the proceduresrelating to the Slidematic faceboware described. However, the Denar ®D31AB Facebow/Earbow may also beused (see Appendix B).Assembling the Slidematicon the PatientMark the anterior reference point on thepatient’s right side using the ReferencePlane Locator and Marker. The point is43 millimeters above the incisal edge ofthe right central or lateral incisors (seeFigure 12). On an endentulous patient,measure up from the lower border of the

Withthe bitefork arm to the patient’s right,place the fork in the mouth, aligning thepatient’s midline with the index notch, sothat it is parallel with the patient’s coronaland horizontal planes (see Figure 13).Be certain to obtain a light indexing ofthe patient’s maxillary arch and then askthe patient to hold the bitefork in place.Attach the vertical shaft to the measuringbow with the clamp marked #2 onthe patient’s right and tighten the fingerscrew (see Figure 14). It is necessaryto tighten this finger screw to securethe vertical shaft to the measuring bowand also to avoid movement. This samemovement will occur after inserting thevertical shaft in the articulator index asshown in Figure 23. Be sure to tightenthe finger screw.Loosen the finger screws on the clampsmarked #1 and #2 on the vertical shaft.With your thumb, loosen the centerwheel on the top of the measuring bowand slide the bow open to accommodatethe width of the patient’s face. Assemblethe facebow on the patient by sliding thebitefork arm through the hole in clamp#2 as the measuring bow’s earpieces areplaced in the patient’s auditory meatus(see Figure 15). Tighten the center wheelon the measuring bow and loosen thefinger screw on the anterior referenceFIG. 15pointer. Raise or lower the bow so thatthe pointer or sight aligns precisely withthe anterior reference point (see figure16) and tighten clamp #1, then clamp#2 (see Figures 17 and 18). When tighteningclamps #1 and #2, care must betaken not to displace the bow to eitherside by having the vertical shaft rest on11
