Laboratory If the clinician has delegated mounting to the lab - oratory, then the records phase has been completed. The following applies to those who mount their own casts.Positionthetabletinthestand6to12inchesfrom thecastandlaunchtheVFapp.Placethemaxillarycast on the articulator mount (Fig. 9).

When the cast is correctly positioned, simply take a photo. Resize and reposition the image if required and save the image. Orientation can be confirmed by altering the transparency of either the face or cast image.Mountthemaxillarycasttotheupperarticula- tor. The record of occlusal contacts (Fig. 8) will then be displayed.Positionthemandibularcasttothemaxillary cast, confirming contacts,and mount the mandibular cast. The VF will then generate a composite of the skull, face and cast. The operator has the ability to alter the transparency of any image to reconfirm the position of the skull to the patient’s face and, ultimately, to the cast (Fig. 11). The laboratory component has been completed(Fig.12).
