142 Orthodontic appliance US631279 1984-07-16 US4588380A 1986-05-13 Douglas E. Toll
An improved orthodontic appliance of the type generally referred to as headgear, for applying a force to a tooth to move the tooth bodily and/or rotationally, and for pushing outward the cheek to encourage spontaneous jaw growth. The appliance comprises an outer bow intended to be retained adjacent the user's face by a neck strap and an inner bow attached to the outer bow intended to fit within the user's mouth proximate to his cheeks. The inner bow includes left and right activating arms, which arms include shoulder portions to push the cheeks outwardly, and which arms also include noncircular engagement means adapted to fit snugly within tubes fixed to a left and a right rear tooth. The activating arms are formable and sufficiently resilient that they can be selectively deformed to apply a force to the teeth to achieve the desired movement. The noncircular engagement means prevents undesired rotational movement between the appliance and the teeth, and assures that the force developed by the arms will be properly transferred to the teeth.

145 Universal facebow US337580 1982-01-07 US4431410A 1984-02-14 Howard J. Ruderman
A facebow for use in orthodontic procedures is provided with relatively universal adjustability to permit use of a single size of facebow in mouths of a variety of different sizes and further facilitating selective unilateral movement. To this end, the facebow is formed with a conventional outer bow for securement to a cervical elastic strap or head gear; and an inner bow contoured to fit into the mouth of the patient along the dental arch, preferably approximating the molars. The inner bow is secured to the outer bow, and the inner bow is formed with at least a pair of mesial loops arranged to lie along the surface of the teeth over which the inner bow is positioned. These loops provide the four-fold function of (1) providing means for the dentist to adjust the effective length of the inner bow by increasing or decreasing the curvature of the loop; (2) permitting selective unilateral pressure to be applied to the dental arch; (3) providing an added variable site for affixing auxiliary attachments, such as hooks and springs; and (4) providing a finger engaging seat to facilitate facebow manipulation. Additional adjusting loops may be arranged along the inner archwire, again oriented in the plane of the wire along the teeth against which the inner bow is positioned, extending either upwardly or downwardly with respect to the wire. The loops are preferably formed of a height between 30% and 300% of the tooth height or "clinical crown," and a spacing between the legs of the loop between 25% and 150% of loop height.

152 Orthodontic appliance US755224 1976-12-29 US4167061A 1979-09-11 Rolf Forster
This invention relates to an orthodontic appliance for correcting the positions of teeth in a jaw. Embodiments of the invention are provided with a low pull and/or a high pull and comprise adjustable spring or rubber elements for transmitting the correcting forces to the teeth. The spring or rubber elements are disposed on the outside of the mouth closely beside the teeth so that the latter are not subjected to disturbing turning and tilting torques. Turning movements of the head and movements of the jaw are compensated. A combination of a high pull and a low pull enables an optimum adjustment of the magnitude and direction of the correcting forces.
153 Vibrational mouth pad orthodontic appliance US752404 1976-12-20 US4123844A 1978-11-07 Craven H. Kurz
An orthodontic appliance in the form of a vibrational pad is provided. The pad is held in place in the mouth of the patient by an external head gear. A vibrational electric motor is mounted on the head gear, and the motor is mechanically coupled to vibrational elements within the mouth pad. The mouth pad is used in conjunction with conventional orthodontic appliances, and it serves to vibrate the teeth being moved by the conventional orthodontic appliances so as to disseminate heavy orthodontic pressures of the conventional appliance to a larger boney mass resulting in lighter more physiological pressure in a larger area. This will increase the speed and efficiency of the orthodontic movement, minimize pain to the patient, and reduce root resorption and horizontal bone loss.

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.
155 Extraoral force-applying orthodontic appliance US794407 1977-05-06 US4115921A 1978-09-26 Maclay M. Armstrong
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.
156 Orthodontic safety face bow US593327 1975-07-07 US4087915A 1978-05-09 Lawrence F. Andrews
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.
157 Orthodontic neck band including safety strap US639757 1975-12-11 US4040188A 1977-08-09 Jacob J. Masel
A safety orthodontic neck band including a resilient band connected at its ends with an extra-oral orthodontic appliance for tensioning purposes when the orthodontic appliance is applied to the teeth of a patient. The apparatus also includes a non-extensible safety band which is co-extensive with the resilient neck band and overlies the resilient neck band in close proximity. The safety band also connects to the ends of the orthodontic appliance to thereby prevent accidental or unwanted movement of the extra-oral orthodontic appliance forwardly relative to the teeth of the patient. The orthodontic neck band including safety strap of the present invention functions to prevent forward movement of the orthodontic appliance and at the same time continuously tensions the appliance during all periods of use.
158 Orthodontic appliance guard US661973 1976-02-27 US4038754A 1977-08-02 Maclay M. Armstrong
Danger of serious injury caused by sharp projections on a displaceable intraoral orthodontic appliance is avoided, or at least greatly decreased, by providing guards alongside such projections or by substituting guards for such projections. Such a guard can be a wire having an enlarged blunt end portion preferably in the form of a loop. The guard wire is mounted alongside the sharp projection of the orthodontic appliance, such as an inner bow anchor tip, and projects beyond such tip. In some instances, the sharp tip, such as a spur, can simply be replaced by a wire having a blunt tip.
