Abstract

Abstract - The KaVo ARCUS digma is an ultrasonic mandibular movement recorder, which provides articulator setting information for Kavo articulators. The first part of this study examined the ability of the device to record condylar control values pre-set on Kavo’s own articulators. Using a mechanical pantograph, the second part of the study tested the ability of the device to record, and then allow reproduction on a Kavo articulator, the movements of a Denar D5A articulator. The device was accurate in recording Sagittal Condylar Inclination, but less so for Progressive Side Shift. Immediate Side Shift was persistently under-recorded. Pantographic tracings demonstrated similar paths of articulator movements so long as Immediate Side Shift was not set.

KEY WORDS: Arcus Digma, Pantograph, Mandibular movement recorder
