  • Patent number: 3987547
    Abstract: The orthodontic appliance comprises a palatal appliance having upper and lower surfaces which is adapted to be inserted into the patient's mouth with the upper surface in surface contact with the palate. A plurality of wire members are attached to the lower surface of the palatal appliance. The wire members each have three sections which respectively project from the lower surface, across the dental arch and to the outside thereof when the palatal appliance is inserted into the mouth of the patient. An arch wire having first and second ends is attached to orthodontic brackets that have been bonded to the patient's teeth. The ends of the arch wire are activated by respectively coupling them to the third section of a pair of the wire members. The coupling of the ends of the arch wire to the wire members obviates the need for buccal tubes to activate the arch wire.

  • Patent number: 3984915
    Abstract: This invention involves the orthodontic movement of live teeth in the mouth by using the forces of magnets. A magnet is attached to the teeth by conventional methods such as adhesive bonding or dental appliances. The magnets are placed on the teeth in such a manner to employ the attraction and repulsion characteristics of a magnetic field. These forces may be employed to align teeth, tilt teeth, move root positions and angulations, torque teeth, and erupt impacted or partially impacted teeth into the correct position in the mouth. The technique may be used alone or in combination with other conventional orthodontic techniques for either major or minor tooth movement. The magnets may be attached anywhere on a tooth, but preferably in an inconspicuous position. The magnets themselves may have tapered edges to insure the teeth move to the proper position.

  • Patent number: 3981079
    Abstract: A dental implant for maintaining a dental prosthetic device in a fixed relation with respect to a jaw bone includes a support post in the form of an internally threaded hollow cylindrical sleeve. The support post is introduced into a complementay cavity formed in the region of the crest of the jaw bone. The support post is provided with at least partially threaded apertures which are spaced from each other along and angularly displaced from each other about the periphery of the support post. Self-tapping anchoring screws extend through preformed blind holes drilled in the jaw bone with the assistance of a jig forming part of the present invention. The preformed holes extend in a direction substantially normal to the support post and are aligned with the apertures in the latter. The anchoring screws threadedly engage the bone and the threaded portions of the support post without extending beyond the preformed blind holes.

  • Patent number: RE28962
    Abstract: Two spaced substantially parallel tabs are supported on a mounting portion which may be in the form of a welding flange connectable to a tooth band. According to the presently preferred embodiment, each of the tabs is provided with a plurality of apertures. At least the wire receiving ends of the apertures are tapered to facilitate location and entry of the arch wire into the respective apertures. By selectively passing the arch wire through preselected apertures, the wire can either be passively positioned in the buccal end tube device wherein it does not exert any forces on the tooth or, alternately, it can engage the device actively wherein rotating as well as tipping forces can be applied to the tooth on which the end tube device is mounted. An end tube device is also described wherein a buccal tube is mounted adjacently to the end tube device and is provided with a slot through which an arch wire can pass interiorly of the tube.
