The phantom head holder P-HA can be used to easily fasten model jaws without demonstration articulator in a phantom head PH-1 in a fixed working position. It also allows the use of the oral cavity mask P-6 GP. P-HA is especially recommended for the local anaesthesia training model AG-3 IB, which cannot be mounted to the hard plastic articulator series DA, DAV or UAV due to its raising branches of the lower jaw.
