    摘要： Orthodontic traction apparatus for applying traction to the teeth of a patient comprising headgear to be worn by the patient including a pair of side members adapted to be positioned on opposite sides of the patient's head adjacent the ears, and a tensioning assembly on each side member for attachment to an instrumentality associated with the teeth for applying traction thereto. Each tensioning assembly comprises a rod mounted in a guide for sliding movement of the rod axially therein. The guide, in turn, is mounted on the respective side member for axial adjustment relative thereto and also for angular adjustment relative to the side member about an axis extending generally in side-to-side direction with respect to the patient's head. A spring biases the rod to slide axially in the guide to apply traction to the teeth.

    摘要： 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 restricted by limiting the normal range of movement of the force-applying elements and such snapback 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 of primary force to the intraoral means and reaction force to the head or neck engageable 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 a linear ratchet device except where the force-producing means is of a negator type which will produce a constant force in various adjusted positions of the negator force-producing means relative to the reaction device and the force-applying 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.

    摘要： A safety face bow having inner and outer wires, the outer wires adapted for coupling to a head cap and/or a neck pad and the inner wires adapted for terminating in an orthodontic buccal tube in which a blunt extension beyond the end of the inner wire is added for the prevention of impalement by the ends of the inner wire if the face bow assembly is pulled out of the patient's mouth. In one embodiment, the outer wire is also removably attached to the inner wire with the additional blunt edge forming a latch for retention of the inner wire should the outer wire be pulled while being worn within the patient's mouth.

    摘要： A manually retractable locking means is provided on the end of the inner arch of an orthodontic appliance, which engages the buccal tube in which the end of the arch resides, thereby to prevent undesired or accidental removal of the arch from the buccal tube. In similar vein the face bow, to which the inner arch is secured, is provided with a stop means associated with the resilient retractive elastic customarily used with the face bow, which prevents the face bow from being completely separated from the neck strap or retaining head gear to which it is secured. In this way a double safety feature is provided to prevent harm to the wearer by the accidental pulling out and snapping back of the face bow and/or the inner arch.

    摘要： Adjustable headgear is disclosed which includes a first or occipital strap having an upper end and a lower end and is adapted to extend from the back of the head of the wearer upward to the top area of the head. A second strap having an upper end and a lower end is adapted to extend from the right side of the head of the wearer upward to the top area of the head. A third strap having an upper end and a lower end is adapted to extend from the left side of the head of the wearer upward to the top area of the head. A top adjustment piece has slits therein through which the upper ends of the straps pass so that the length of each strap from its lower end up to the adjustment piece can be adjusted by sliding the strap through the slits in the adjustment piece. Backstrap means has forward end portions connected to the lower ends of the second and third straps and extends around from the lower end of the second strap to the lower end of the third strap. The lower end of the first strap is connected to the strap means generally centrally of the latter.

    摘要： A modifiable orthodontic facebow is disclosed which is used with the head-strap and/or neck-pad for treating orthodontic cases. The modifiable orthodontic facebow of the present invention comprises an inner bow adapted to be inserted into a buccal tube of a molar band and an outer bow connected to the inner bow by means of an anterior hinge, wherein the anterior region of the outer bow is connected to the posterior region of the outer bow through a pair of side hinges comprising a first section and a second section, wherein the posterior region of the outer bow comprises a plurality of interconnected units, wherein a first interconnected unit is fixed to the second section of the side hinge followed by a plurality of intermediary interconnected units with a terminating unit comprising a j-hook to secure an elastic band.
