[The usefulness of the mandibular kinesiograph (MKG)]

The Jankelson mandibular kinesigraph is intended to reproduce the movements of the mandible electronically. Analyses of the measurements and clinical studies of linearity, reproducibility, and susceptibility to the electromagnetic fields showed that quantitative and qualitative evaluations of the recordings are impossible. The device therefore appears to us to be unsuitable for the clinical diagnosis of abnormal movements of the mandible and disturbances in occlusion.
