  • Patent number: 6299440
    Abstract: The present invention provides methods and systems of repositioning teeth for use in orthodontic treatment, with particular applicability to removable elastic repositioning appliances. Such appliances may be challenged by traditional tooth movements which intrude the crown of the tooth or present tooth positions which reduce available points of purchase. These challenges may be overcome with a series of tooth movements in which a tooth is translated in a “root-first” position. The movements may take advantage of the inherent characteristics of elastic repositioning appliances in translating a tooth from a first position to a desired position along a gingival plane.

  • Patent number: 6227861
    Abstract: A preformed mandible splint and a method of aligning and stabilizing a fractured mandible with such a splint is disclosed. The splint is configured to approximate the curvature of the lower teeth or the gingiva of the lower jaw. The curvature of an eight inch diameter sphere approaches the geometric curvature of the human teeth and gum, therefore, the similarly configured splint of the present invention is usable for almost any child or adult. The splint is approximately U-shaped, follows the human dental arcade, and has rows of holes or slots along its outer and inner perimeter. The splint is placed on the teeth or gingiva and wired through the holes or slots to the mandible thus correctly aligning the mandible. Fractures can then be screwed into place according to the curvature of the splint. This eliminates the need of wiring the patient's jaw shut as is presently done in current interdigitation techniques where even minute errors in mandibular repair results in flagrant morbidities in the patient.

  • Patent number: 6074207
    Abstract: An orthodontic device and associated method for altering the position of a tooth in the mouth. The orthodontic device includes a bracket that attaches to the tooth or teeth that are to be moved. A bite plate is produced that is contoured to engage teeth on both the maxillary arch and the mandibular arch, other than the tooth to be moved. The bite plate can be a single piece unit or a two piece unit that can be joined within the mouth. A spring element is disposed between the bite plate and the bracket. The spring element applies a spring bias between the bracket and the bite plate. Since the spring bias acts on the tooth to be moved and the bite plate, the spring bias acts to correct the position of the tooth to be moved without any significant effect on the other teeth in the mouth.

One of the lingual arch developers disclosed uses magnets to have an effect on the mesial advancement of the lingual arch. The lingual arch of this developer may be interconnected with the patient by a connector which includes at least one and preferably two vertical posts which are insertable into corresponding vertical tubes fixed to a band on a patient's tooth. At least one generally horizontal tube is interconnected with these posts. In one embodiment this tube is gingivally disposed to, for instance, slidably interface with a lingual arch. This connector may be used as an interface between the patient and other orthodontic appliances as well. For instance, the noted tube on the connector may be generally gingivally disposed to, for instance, interface with a palatal expander.

  • Patent number: 5853291
    Abstract: A subperiosteal bone anchor has a base that is thin and moldable so the base can be conformed to bone where it is to be placed. The base is formed as a plurality of arms, and leaves with central holes in the leaves so screws can urge the leaves against the bone. The edges of the base are scalloped, and very thin to facilitate bone overgrowth. Central to the arms is a stem extending up, and having a variety of connection mechanisms for attachment of orthodontic appliances.

  • Patent number: 5823772
    Abstract: An orthodontic spring is comprised of a wave spring made of shape memory alloy that consists of a wire tightly looped, once or many times back on itself, side-to-side in figure "8"fashion. After winding, the spring is heat treated into this position. In its relaxed state, the bends of the spring form peaks and valleys which lie in parallel planes at an angle to the line of force between attachment loops at opposite end points of the spring. Portions of the wire between successive peaks and valleys overlap other portions between other peaks and valleys when the wire is relaxed. When extended, the elements of the spring lie in a longitudinal plane along its line of force. The spring is particularly suited to attachment between closely spaced points, such as brackets affixed to adjacent teeth.

  • Patent number: 5820369
    Abstract: A subperiosteal bone anchor used in two distinct applications; as an orthodontic anchor system, and as an orthopedic anchor system. As an orthodontic anchor system, it is used for treatment of growth disharmony and malalignment of the teeth in which the subperiosteal bone anchor is surgically placed in the subperiosteal tunnel on skeletal bone allowing osseointegration between the subperiosteal bone anchor bone interface and the bone. After osseointegration a palatal bar or palatal wire is attached to the cylinder of orthodontic anchor system, which is attached to the abutment, which is attached to the subperiosteal bone anchor, and the palatal bar or palatal wire is also attached to bands around one or more teeth, holding them immobile. As an orthopedic anchor system the subperiosteal bone anchor is used to stabilize devices which need to be anchored to a bone, or to transmit attractive or distractive forces to a bone for reconstruction or transformation.

  • Patent number: 5752823
    Abstract: An orthodontic appliance having improved devices for interconnecting the braces associated with a patient's upper and lower teeth. Each connecting device generally takes the form of a unitary, thin band of material that can be connected between the braces associated with the patient's upper and lower teeth to achieve the forces that are desired for a particular treatment. The connecting device generally includes a body having integral end portions that are preferably rounded for purposes of comfort. Each end portion includes an attachment for connection to the braces associated with the patient's teeth. Preferably, at least one of the attachments of each connecting device is keyed so that upon its connection to the braces, swivelling of the connecting device is effectively precluded without compromising desired movements of the connecting device relative to the orthodontic appliance and the patient's mouth.

  • Patent number: 5738514
    Abstract: An orthodontic appliance has two telescoping cylinders having springs therein to urge the cylinders apart. The outer cylinder is then slidably inserted into a third cylinder. The outer ends of the cylinders are attached to a patient's teeth so the springs exert a force on the teeth when the spring-urged cylinders contact the end of the third cylinder. The cylinders may be separable so the springs can be exchanged, or may be permanently fixed together. The attachments allow universal motion so the lower jaw can move to the full extent of the normal jaw without binding or destroying the appliance.

  • Patent number: 5692895
    Abstract: Luminescent orthodontic appliances, such as brackets, archwires, bands and the like, having a luminescent pigment or mixture of luminescent pigments are described. In a preferred form, the luminescent pigment is a phosphorescent pigment comprising zinc sulfide doped with copper. The pigment gives the appliance a natural appearance in daylight and causes it to emit a greenish-white light in the dark after having been energized by an excitation light source. If desired, the luminescent orthodontic appliance may be made with a fluorescent pigment or a combination of fluorescent and phosphorescent pigments. If a fluorescent pigment is used, the bracket will exhibit a luminescence in daylight; whereas if a mixture of fluorescent and phosphorescent pigments are used, the appliance will luminesce in the dark after having been exposed to a light source, in addition to exhibiting a luminescence in the daylight.
