Publication number: 20140076465Abstract: Metal ingots for forming single-crystal shape-memory alloys (SMAs) may be fabricated with high reliability and control by alloying thin layers of material together. In this method, a reactive layer (e.g., aluminum) is provided in thin flat layers between layers of other materials (e.g., copper and layers of nickel). When the stacked layers are vacuum heated in a crucible to the melting temperature of the reactive layer, it becomes reactive and chemically bonds to the other layers, and may form eutectics that, as the temperature is further increased, melt homogeneously and congruently at temperatures below the melting temperatures of copper and nickel. Oxidation and evaporation are greatly reduced compared to other methods of alloying, and loss of material from turbulence is minimized.Type: ApplicationFiled: January 8, 2013Publication date: March 20, 2014Applicant: ORMCO CORPORATIONInventor: Ormco Corporation

Publication number: 20130224676Abstract: An orthodontic appliance for use in orthodontic treatment. The orthodontic appliance is selected from the group consisting of an orthodontic bracket, an orthodontic archwire, an orthodontic tool, and a discrete component thereof. The orthodontic appliance is made of a metallic glass. The orthodontic appliance may be an orthodontic bracket for coupling an archwire with a tooth. The orthodontic bracket comprises a bracket body including an archwire slot, the bracket body being made of a metallic glass. The orthodontic bracket further comprises a movable member made of a metallic glass and operatively coupled to the bracket body and movable between an opened position in which the archwire is insertable into the archwire slot and a closed position in which the movable member retains the archwire in the archwire slot. The orthodontic bracket further comprises a pin coupling the movable member to the bracket body.Type: ApplicationFiled: February 25, 2013Publication date: August 29, 2013Applicant: ORMCO CORPORATIONInventor: ORMCO CORPORATION

Publication number: 20130189638Abstract: An orthodontic bracket having a bracket body configured to be mounted to a tooth includes an archwire slot having a base surface defining a base plane and a slide engagement track defining a translation plane. The translation plane is angled with respect to the base plane. A ligating slide is engaged with the slide engagement track of the bracket body and movable along the slide engagement track and parallel to the translation plane between an opened position, in which an archwire is insertable into the archwire slot, and a closed position, in which the archwire is retained within the archwire slot. The translation plane is angled with respect to the base plane so as to prevent the ligating slide from contacting the gingiva surrounding the tooth when the ligating slide is moved to the opened position.Type: ApplicationFiled: March 10, 2013Publication date: July 25, 2013Applicant: ORMCO CORPORATIONInventor: Ormco Corporation

Publication number: 20130122448Abstract: A method for fabrication of an orthodontic device having tooth-fitting cavities, such as an aligner, using layer-by-layer printing of a single or multiple polymeric materials. The cavities of the appliance or an appliance mold are defined by the boundaries of the multiple layers, encapsulating up to fourteen teeth of a patient, and shaped to apply a load to at least one tooth that is sufficient to cause movement of the tooth, and remodeling of the adjacent bone. In the case where the cavities form an appliance mold, the mold is used to form a positive model and an appliance is formed thereon. A series of such appliances may be used to treat malocclusion of teeth, each appliance used in series to incrementally move one or more teeth from initial positions toward a desired final position. The appliance may be fabricated with a variety of disclosed materials, and may include auxiliary features for interaction with other orthodontic elements.Type: ApplicationFiled: January 10, 2013Publication date: May 16, 2013Applicant: ORMCO CORPORATIONInventor: ORMCO CORPORATION

Publication number: 20130101952Abstract: A dental apparatus for use with a connecting member coupled to a jaw in a patient's mouth. The apparatus includes an orthodontic device and a connecting device carried by the orthodontic device. The connecting device includes a receptacle adapted to partially receive the connecting member and a blocking member. The blocking member is moveable relative to the receptacle between an opened position in which the connecting member may be disengaged from the receptacle and a closed position in which the connecting member is captured within the receptacle for pivotally engaging the orthodontic device with the connecting member. The orthodontic device may further include a biasing member selectively activated to provide a spring-biased force to the jaw. A method of using the dental apparatus includes moving the blocking member to capture/release the connecting member in the receptacle and activating/deactivating the biasing member to operate the apparatus in a different mode.Type: ApplicationFiled: December 7, 2012Publication date: April 25, 2013Applicant: ORMCO CORPORATIONInventor: ORMCO CORPORATION

Publication number: 20130095446Abstract: A method for direct fabrication of an orthodontic device having tooth-fitting cavities, such as an aligner, using layer-by-layer printing of a single or multiple polymeric materials. The cavities of the appliance are defined by the boundaries of the multiple layers, encapsulating up to fourteen teeth of a patient, and shaped to apply a load to at least one tooth that is sufficient to cause movement of the tooth, and remodeling of the adjacent bone. A series of such appliances may be used to treat malocclusion of teeth, each directly manufactured appliance used in series to incrementally move one or more teeth from initial positions toward a desired final position. The appliance may be fabricated with a variety of disclosed materials, and may include auxiliary features for interaction with other orthodontic elements.Type: ApplicationFiled: October 12, 2012Publication date: April 18, 2013Applicant: ORMCO CORPORATIONInventor: Ormco Corporation

Publication number: 20130078593Abstract: An orthodontic aligner of the type that is deformable from its initial shape to a deformed shape when fitted upon a patient's teeth in order to apply a load to the teeth to move the teeth to an orthodontically preferred position is made from a polymeric material that generates a continuing elastic return stress driving toward the initial shape after a substantial period of continuous deformation, such as longer than one day and up to or exceeding two weeks. Elastic stress loads applied to teeth over such durations cause greater remodeling of the bone adjacent to a tooth's roots than is possible with known aligner materials.Type: ApplicationFiled: September 28, 2012Publication date: March 28, 2013Applicant: ORMCO CORPORATIONInventor: ORMCO CORPORATION
