for recording of vertical dimention we use:
a- Willis Gauge.***
b- caliper.
c- Face bow.
Resting face height is assessed using:
• A Willis gauge, to measure the distance between the base of nose and the underside of the chin. Is only accurate to ±1 mm.
• Spring dividers, to measure the distance between a dot placed on both the chin and the tip of the patient's nose. This method is less popular with patients and is C/I for bearded gentlemen (or ladies!).
• The patient's appearance and speech.
Willis gauge is used to record the occlusal face height of the the patient.
A face-bow is a caliper-like device used to record the patient's maxilla/hinge axis relationship (opening and closing axis). It is also used to transfer this relationship to the articulator during the mounting of the maxillary cast.
