Reproducibility of the Muscular Contact Position

Abstract

The reproduction of a habitual (natural) closing movement is considered to be important because this closing movement ends at the muscular contact position (MCP), otherwise known as the intercuspal position (ICP). This closing movement was originally regarded as a hinge-like movement. However, since it has been demonstrated to be a bodily movement, that is, a vertical movement, this vertical movement can be reproduced on an articulator.
