Abstract: An apparatus, method and kit are provided for registering a human jaw with a CT image of the human jaw. The apparatus includes a moldable retainer and an arm having a moldable link portion and a rigid fixation portion. The link portion is attachable to the retainer and hardenable to maintain a fixed mapping between the fixation portion and the retainer. The fixation portion includes a CT marker connection region for detachably attaching a CT marker that includes a fiducial. The fixation portion also includes a tag connection region for detachably attaching a tag that is trackable by a pose measurement system. The pose of the tag connection region relative to a pose of the CT marker connection region is fixed prior to attaching either the tag or the CT marker, providing a known and fixed tag to fiducial coordinate mapping.
