The angle of the sagittal condylar path is determined on the registration card with a protractor. The correction factor should be calculated. For each 1mm of opening between the incisors half a degree should be added to the measured angle indicated on the registration cards.
This calculated inclination is used to set the angle of the sagittal condylar paths onto the Condylator.
The Facebow with transfer plate (106) is fixed to its stand. The model is firmly connected to the lower transfer plate by means of registration keys. The two writing points have to be closest to the center of the lateral Condylator double cones. The horizontal rods are parallel to the surface of the bench. A plaster-key has to be made mounting the lower model to the Condylator. As soon as the plaster is set the Facebow is carefully disconnected from the transfer plate. The Facebow is now no longer required.
The lower model is mounted to the Condylator. The upper and lower models have to be connected by the registration keys as a result of the intraoral registration. A plaster-key has to be made mounting the upper model to the Condylator.
