To obtain the incline planefor the articulation, we place a wax coneas near the heel of the lower bite-plateas we can. The two bite-plates are intro-duced into the mouth, and the patientis instructed to protrude the lower aboutone-quarter of an inch, being sure that Fig. this takes place on both sides. This canbe done by observing the median line,noting that one is directly above theother. The patient is now requested toclose the jaws until the two bite-platesare in contact in front; they are stapledtogether firmly, and removed together,then replaced upon the mounted casts,extending the lower as far as necessary, and adjusting the mandibular fossa oneach side to conform to this measure-ment, and locking them with the screws.(See Fig. 24.) By observing Fig. 21, which showsthe face-bow in position and the castsmounted, it will be seen that the castsare far from being in the center betweenthe two articulations, and it will benoted that the case belongs to the scalenetype of a very distinct character.
