A dental clutch member molded in the form of a thin-walled shell fits over the person's lower teeth and is attached thereto by plaster. Holes in the walls of the shell help the plaster become firmly attached to the shell. Support structure molded integral with the shell extends outwardly through the patient's mouth for receiving a horizontal rod to which is attached other dental apparatus. Fracture lines in the shell and the extension permit the shell to be broken into pieces to facilitate removal of the clutch from the patient. One or more tooth separators are molded with the clutch member and then broken away from the shell to be releasably attached to the clutch by detent buttons. |
