  • Patent number: 11510756
    Abstract: A method for treating orthodontitis (i.e., gingivitis caused by malpositioned teeth). The process includes evaluating improper morphologies of alveolar bone in the horizontal dimension (i.e., orthodontosis) caused by displaced root(s) of a tooth, uprighting the root of the malpositioned tooth utilizing an orthodontic bracket system thereby causing the alveolar bone to be restored, which in-turn alleviates the orthodontitis. An orthodontic bracket is provided for use with an arch wire to apply corrective forces to a tooth. The bracket includes a vertical member having a slot formed therein for receiving the arch wire and a wide base horizontal member connected to the vertical member. The vertical member is positioned gingivally with respect to the horizontal member. The horizontal member includes opposing first and second ends that extend away from the vertical member and define a pair of spaced-apart wire engaging points engageable with the arch wire during treatment.

The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.

    Abstract: The present invention relates to an orthodontic bracket specifically designed for use with the deciduous teeth and method for its use. The bracket is unique in providing a debonding tab which reduces the potential for damage to the tooth due to the application of excessive force during the debonding process. The small size of the bracket allows it to fit available crown space on the deciduous teeth. Further the bracket is modified in shape to minimize mechanical forces applied to the deciduous teeth when engaged with an archwire. The bracket base is shaped to conform to the morphology of the deciduous tooth crown surface thereby providing an optimal adhesive interface with the deciduous tooth. The deciduous bracket provides adequate adhesion to avoid unwanted detachment of the bracket which often occurs when the use of permanent brackets is attempted on the deciduous teeth.

  • Patent number: 10085823
    Abstract: The present invention provides methods and systems including orthodontic tooth positioning appliances. An exemplary appliance can include teeth receiving cavities shaped such that, when worn by a patient, repositioning the patient's teeth from a first arrangement toward a subsequent or target arrangement. Appliances can include a cavity having one or more shaped features or protrusions shaped and/or positioned so as to apply a desired force to a patient's tooth received in the cavity and move the tooth along a desired path or direction.

  • Patent number: 9993317
    Abstract: An orthodontic correction appliance may be directly connected to upper and lower removable orthodontic aligners to treat a Class II malocclusion. In some examples, the correction appliance has two elongated sections that are slidably connected to each other and allowed to move back and forth relative to each other. The ends of the two elongated sections can be attached to connectors extending from the removable aligners. In addition, the correction appliance can carry a biasing member that is connected to each of the two elongated sections of the appliance. The biasing member may bias the ends of the two elongated sections away from each other, providing a force to treat the Class II malocclusion while the patient is wearing the upper and lower removable orthodontic aligners.

  • Patent number: 9801755
    Abstract: A tongue grasping and restraining device holds the tongue securely during sleep in order to minimize the risk of the tongue slipping back and blocking the throat. Plural tongue gripping projections are coupled to upper and lower supports. One or more of the upper and lower supports are biased together into a tongue engaging position. A tongue depressor can extend rearwardly and downwardly from the upper support to depress the user's tongue to further open the user's airway. The position of the tongue depressor can be adjustable. The upper support is coupled to the user's upper jaw, for example, to a denture, dental appliance or other form of an upper jaw coupler and can be pivoted thereto. The lower support can be hinged to, fixed to, or otherwise joined to a lower jaw coupler. A tube and rod mechanism can couple the jaw couplers together.

  • Patent number: 9795460
    Abstract: A tooth-positioning appliance for closing spaces has at least two appliance segments, each segment having a thin elastomeric shell with recesses for removably engaging a set of teeth, and tooth-clasping elements for removably engaging bonded attachments protruding from the teeth. One of the appliance segments includes a flat receptacle extending horizontally on the thin shell of the appliance segment, and the other appliance segment has a thin elongated tab extending laterally from the second appliance segment spanning the space to be closed, and in sliding engagement with the flat receptacle of the other appliance segment. An activating element is connected between the appliance segments to exert a force to change the size of the space between the sets of teeth as the tab slides with respect to the flat receptacle.

  • Patent number: 9649176
    Abstract: Orthodontic devices for segmental distalization in a patient are provided. The orthodontic device includes an elongated central arm; a distal part comprising a distal base surface adapted for attachment to a lingual surface of a molar, wherein the distal part is located at a distal end of the central arm. The device also includes a mesial part comprising a mesial base surface adapted for attachment to a lingual surface of a premolar, wherein the mesial part is located at a mesial end of the central arm. The mesial part and/or distal part comprising a first retention element for retention of a first end of an elastic element. The central arm is shaped to substantially follow a lingual side of a set of teeth. The present disclosure further relates to orthodontic kits and to methods for mounting orthodontic devices and to methods for treatment of malocclusions.

  • Patent number: 9539066
    Abstract: An orthodontic appliance has a post attached to a first upper tooth, and a button with a recess attached to a second upper tooth. An elongated arm has an eye at one end through which the post is inserted to allow the elongated arm to rotate about the post, and a tip at the other end for removable insertion into the recess of the button. The length of the elongated arm is selectable to maintain a desired spacing between the first and second upper teeth (e.g., by cutting the tip of the elongated arm). An elastic extends from either the post or button to an attachment point on the patient's lower dental arch to exert a force between the patient's maxilla and mandible.
