Abstract
For the purpose of applying the mandibular kinesiograph (MKG) to the analysis of the abutment tooth movement to evaluate the partial denture design, the characteristic aspects of the MKG record were examined. The rectangular lattices resulting from shifting the magnet in the mesio-distal, right-left, and up-down directions were considerably distorted on the display. However, it was assumed that the three dimensional movement of the tooth could be approximately estimated by a simple correction of the record utilizing those distorted lattices in the sagittal, frontal and horizontal views. If only the record is appropriately interpreted on the basis of the characteristic aspects of the MKG, the MKG method may be valid for estimating the abutment tooth movement in evaluating the design of partial prostheses.
