The present invention relates to a device for determining tentative centric occlusion of an upper and a lower of a patient. The device generally has a bite block which surrounds a handle. The bite block has an inner layer of hard wax surrounded by an upper and lower layers of soft wax. Tracks can be put in the exposed surfaces of the soft wax to generally conform to the patient's upper and lower existing teeth or gums. Recessed areas can be placed in the hard wax to generally receive the existing teeth of the patient. When recessed areas are used, ridges exist in the soft wax to fill the recessed areas. The soft wax is intended to allow proper impression of the exposed gingiva whereas the hard wax is necessary for obtaining the impression of the existing teeth.
