Abstract: A ceramic orthodontic bracket has a centrally located clip for retaining an archwire in an archwire slot. The body of the bracket includes a mesial section, a distal section, and a bridge section, wherein the bridge section extends through, and retains, the clip. The bridge section also includes a recess adjacent to the bridge section that facilitates debonding of the bracket from a patient' s tooth. Preferably there are gaps on one or both sides of the clip to allow space for debonding of the bracket by applying a mesial-distal compressive force on the bracket and fracturing the bracket along the recess. This configuration allows the overall mesial-distal width of the bracket to be reduced, thereby facilitating the bonding of brackets to narrow and/or maloccluded teeth. Another embodiment includes a stop member that is connected to the base of the bracket and retains the clip on the bridge section.

Abstract: The invention relates to a method and a kit for correcting dental malocclusions. The inventive kit consists of at least one pre-formed arch for nitinol orthodontics and at least two perforated silver spherules which when introduced into the arch and deformed remain fixed to the arch, serving as a stop element. The inventive method consists in: positioning the necessary elements; aligning the teeth with the application of the preformed nitinol dental arch, having stop elements abutting thereagainst; closing the spaces; performing a leveling step; and applying a pretorque and a torque.

Abstract: Self-ligating orthodontic brackets, each of which is formed of materials exhibiting shape memory and includes a base from which extend at least one tie wing. The tie wing includes a pair or tie wing posts which are normally spaced to retain an archwire within the guide slot. At least one of each pair of opposing tie wings is flexible and/or yieldable relative to the other to permit insertion and/or removal of the archwire relative to the guide slot. Portions of the brackets may be coated to reduce friction between the archwire slot and the archwire and to promote aesthetics and overall bracket appearance.

Abstract: An electromagnetically induced cutting mechanism which can provide accurate cutting operations on both hard and soft materials is disclosed. The electromagnetically induced cutter is capable of providing extremely fine and smooth incisions, irrespective of the cutting surface. Additionally, a user programmable combination of atomized particles allows for user control of various cutting parameters. The various cutting parameters may also be controlled by changing spray nozzles and electromagnetic energy source parameters. Applications for the cutting mechanism include medical, dental, industrial (etching, engraving, cutting and cleaning) and any other environments where an objective is to precisely remove surface materials without inducing thermal damage, uncontrolled cutting parameters, and/or rough surfaces inappropriate for ideal bonding. The cutting mechanism further does not require any films of water or any particularly porous surfaces to obtain very accurate and controllable cutting.

Abstract: An adjustable orthodontic band conforms around teeth of varied sizes. The band may be elastic or a superelastic alloy, and elastically expands under force to fit different teeth. Or the band has shape memory, e.g. shape memory metal alloy, with variable circumference under applied energy such as heat. The band may be solid heat shrink or elastomeric polymer, or metal alloy. Or, interconnected struts are separated by voids that may receive cement or are covered with elastomer. Adjustability may vary along the band. A kit of adjustable bands has varied adjustable size ranges, and may include no more than about 8 or fewer bands together covering an overall range of up to 30% or more difference in circumference. One band having at least a 30% range of adjustable circumference also may be provided for each tooth type. The adjustable bands are pre-coated with cement, and are pre-packaged in a UV and moisture protective container. Estimated size is all that is required to choose the correct band for most teeth.

Abstract: An improved dental appliance system, and methods for using and fabricating the improved appliance, including a polymeric overlay or shell having a teeth-receiving cavity formed therein. The dental appliance having the necessary stiffness or strength to firmly secure the appliance on the teeth and provide controlled forces required for repositioning the teeth, until such time as removal of the appliance is desired. The appliance may be configured for use with a removal mechanism. The removal mechanism provides for selective release of the appliance from the teeth as the removal mechanism undergoes a state change stimulated by an environmental stimulus or environmental switch.

Abstract: Fabrication of metal medical instruments and devices from a shape memory alloy which provides greater flexibility in design and avoids the need for substantial cold working of the alloy which is required in other methods. The new process provides a ductile alloy for ease of forming and a unique heat treatment which renders the fabricated orthodontic and medical components highly elastic, with a high resistance to kinking and with good corrosion resistance. In addition, this new process produces orthodontic and medical components useful over the temperature range of from −20 to +40 degrees C.

Abstract: A superelastic endodontic instrument, such as a file, is formed by grinding a superelastic wire to form a file preform or blank, and rotating a first end of the blank while preventing rotation of a second end of the blank. The file blank is maintained in the austenite phase at least until twisted to form a stress induced martensite which is plastically deformed by the twisting. A heat treatment step may be performed prior to twisting, during twisting or after twisting of the preform. The file blank may be heated by electrical heating methods or by submerging the blank in a heated liquid.
