ABSTRACT:
An extraoral force-reaction device engageable with the wearer's head and/or neck, such as a headcap or a neckband, is connected to an intraoral force-applying device, such as molar bands, by force-producing means, such as springs. Snapback of the force-applying means is controlled in response to relative movement of the intraoral means and the extraoral force-reaction means away from each other beyond a predetermined maximum limit, or in response to stressing of the force-producing means beyond a predetermined maximum degree of force exerted by the force-producing means. Snapback control may be effected by latching of a limit latch to prevent or limit return movement of the force-reaction device and the force-applying device, or disconnectible means can be disconnected to interrupt the application to the intraoral means of force capable of moving such intraoral means. The force to be exerted by the spring force-producing means can be readily adjustable in predetermined increments, such as by engagement of different holes in a spring anchor strap with an anchor pin, or by engaging a spring end hook selectively with any anchor post of several posts arranged in a row lengthwise of the spring, or by a linear ratchet device. Also, various components of the extraoral force-reaction device can be assembled and adjusted as to length by connection of separable connections, which may include linear ratchet means.
