Comparison of the most comfortable mandibular position with the intercuspal position using cephalometric analysis.

For evaluation of the most comfortable position (MCP) in edentulous subjects, as decided by mandibular position sense, the MCP was recorded in ten edentulous subjects and compared with the intercuspal position (ICP) of normal dentate persons. It was found that the MCP was at a lower mandibular position than the ICP; the facial height was markedly reduced in the former by a front-upward rotation of the mandible centering around the condyles. Thus, it has been suggested that the occlusal vertical dimension (OVD) of the MCP in the restored dentition is less than that of the original ICP.
