  • Patent number: 10383704
    Abstract: 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.

    Abstract: Orthodontic positioning devices, and related methods and systems, are disclosed for use with one or more orthodontic elastic members. The disclosed devices are configured to couple with an orthodontic elastic member so as to react a force from the elastic member into the appliance to, for example, generate traction forces on the patient's teeth to produce a desired occlusion. A positioning device includes a patient removable tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient's teeth. The appliance includes a hook configured to interface with an orthodontic elastic member. The hook can be configured to be offset from a surface of a tooth when the appliance is coupled with the patient's teeth and no elastic member is coupled with the tooth. The hook can be curved so that the hook is more retentive on the aligner. The hook can be reinforced so that the reinforcement resists deformation when the elastic is in place.

    Abstract: An oral device for temporary placement in a patient's oral cavity includes upper and lower jaw braces and a tongue-engaging member. The upper and lower jaw braces are connected so that the lower jaw brace is advanced in an anterior direction relative to the upper jaw brace when the upper and lower jaw braces are closed together. A partial vacuum is drawn in the oral cavity and the vacuum and lower jaw displacement together control the position of the tongue in order to clear the patient's airway to reduce sleep apnea or treat other conditions.

  • Patent number: 9192505
    Abstract: A custom oral splint that is operatively secured to the maxilla and mandible of a subject/patient to assist in reduction and provide maintenance of reduction of maxillary and mandibular fractures in the edentulous or partially edentulous subject/patient. In this difficult patient population, there are very limited options for maxillomandibular fixation, and none provide stable reduction of fractures. The novel device minimizes operative time and equipment, as well as offers the ability to transition the patient from rigid fixation to elastics postoperatively. The novel device is custom-designed for each patient's degree of bone atrophy, ensuring a high quality, and effective product.

  • Patent number: 9161823
    Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems of the invention include tooth attachments having improved or optimized parameters selected or modified for more optimal and/or effective application of forces for a desired/selected orthodontic movement. Attachments of the present invention can be customized to a particular patient (e.g., patient-customized), a particular movement, and/or a sub-group or sub-set of patients, and configured to engage an orthodontic tooth positioning appliance worn by a patient, where engagement between the attachment and orthodontic appliance results in application of a repositioning force or series/system of forces to the tooth having the attachment and will generally elicit a tooth movement.

  • Patent number: 9161824
    Abstract: A computer is used to create a plan for repositioning an orthodontic patient's teeth. The computer receives an initial digital data set representing the patient's teeth at their initial positions and a final digital data set representing the teeth at their final positions. The computer then uses the data sets to generate treatment paths along which the teeth will move from the initial positions to the final positions.

  • Patent number: 9119691
    Abstract: The present invention provides orthodontic appliances and systems, and related methods, for applying a force to a target tooth as an appliances is worn by the patient. One positioning appliance includes a tooth positioning appliance having teeth receiving cavities shaped to apply a positioning force to the patient's teeth. The appliance includes a spring-loaded tooth movement device disposed in the appliance so as to engage an attachment mounted on a surface of a patient's tooth and apply a force to the tooth.

  • Patent number: 9084657
    Abstract: Embodiments include dental appliances, dental appliance systems, and methods of making and using such appliances. In one embodiment, a dental appliance includes a shell having a number of cavities to receive one or more teeth, each cavity having an inner surface. At least a first portion of a particular cavity is scaled-up in size by a first selected percentage over one or more dimensions of a corresponding tooth to provide a first space between the cavity inner surface and the corresponding tooth surface. At least a second portion of the particular cavity is scaled-up in size by a second scaled-up percentage over one or more dimensions of a corresponding gingival outer surface adjacent to the corresponding tooth to provide a second shape.

  • Publication number: 20150140501
    Abstract: The present invention relates to a clear aligner, a manufacturing method thereof, a traction device for a clear aligner, and an auxiliary tool for a traction device for a clear aligner. More particularly, the present invention relates to a clear aligner (10), a manufacturing method thereof, a traction device for a clear aligner, and an auxiliary tool (40) for a traction device for a clear aligner, wherein the clear aligner can improve orthodontic effects by increasing a correction force by traction of a clear aligner using an elastic band when it is impossible to correct teeth only with the clear aligner due to uneven teeth.
