摘要： Apparatuses (e.g., distalizers) and methods for distalizing a subject's teeth while preventing or reducing undesirable tipping and/or rotation of the teeth. The distalizer apparatuses may include tooth engagement regions shaped to accommodate molars, canines and/or premolar teeth, may include a transpalatal region extending between engagement regions having an anterior edge that is posterior to a premolar region of the first tooth engagement region, and may include an attachment site for an elastic band on the outer buccal surface.

摘要： According to the techniques herein, one or more sensors coupled to an aligner are used to sense one or more physical qualities of the aligner to determine whether the physical qualities indicate that the aligner material has relaxed and has, e.g., reduced the force systems applied to teeth and/or that the teeth movement for the stage has slowed down. The sensors may provide a signal that represents whether or not the physical qualities fall below a threshold value. A treatment plan may be modified if needed. These techniques have the potential to make treatment plans faster and more effective by speeding up some stages while making sure some, perhaps other, stages are implemented only after the teeth are near the appropriate position.

摘要： Methods and apparatuses (including software) for optimizing dental treatment plans, including for optimizing the treatment plans using dental aligners. These methods and apparatuses may optimize a treatment plan by estimating a difference between a target set of tooth position and a predicted set of tooth positions using the treatment plan using a prediction network trained to use multiple translational and rotational directions for individual teeth as well as reaction forces on the individual teeth based on adjacent teeth.

摘要： Apparatuses and methods for assessing a dental x-ray image and predicting tooth eruption and/or exfoliation. The apparatuses may use one or more trained neural networks to assess a patient's x-rays as well as dental measurements determined from the patient's x-rays to predict approximately when a permanent tooth may erupt to replace a baby tooth. The neural networks may be trained using a data training set of x-ray images and accompanying dental measurement data.

摘要： Methods and systems are provided for generating a treatment plan for arch expansion where a polymeric shell appliance is utilized to generate one or more activation forces that facilitate tooth movement. The polymeric shell appliances may comprise one or more tooth receiving cavities, in which each of the plurality of tooth receiving cavities is shaped and arranged to provide a counter moment of each of the plurality of teeth.

摘要： Apparatuses and methods for customized retainers to prevent relapse. In particular, described herein are customized retainers, and methods and apparatuses for making customized retainers that specifically reenforce and prevent movement of one or more teeth having a higher likelihood of relapse following completion of an orthodontic treatment plan.

摘要： A method for generating and fabricating a dental device having a body. The body may have a first plurality of tooth receiving cavities shaped to receive teeth of a first side of an arch. The body may also have a second plurality of tooth receiving cavities shaped to receive teeth of a second side of an arch. A palatal portion may extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities. The palatal portion may be shaped to apply an expansion force to the teeth of the first side of the arch and the teeth of the second side of the arch. The palatal portion may include a plurality of bands that extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities, each respective band may have a respective different thickness.

摘要： A dental attachment placement device comprises a plurality of registration elements shaped for placement on a plurality of teeth and one or more flexible arms for biasing the registration element to a tooth. A first a first flexible arm may extend from a registration element on a lingual side. The first flexible arm may have a connected end and a distal end. The distal end may be configured to extend at least part way over the tooth and apply a lingual force to bias the registration element against the tooth.

摘要： A system may include a body having a palatal portion of a first material and a surface shaped to match a shape of a patient's palate and extending between first tooth engagement structures shaped to engage teeth on a first side of a patient's arch and second tooth engagement structures shaped to engage teeth on a second side of a patient's arch and a reinforcement structure within the palatal portion, wherein the reinforcement structure includes at least one fiber fabricated of a second material, different than the first material, and a dimension of the at least one fiber at a middle portion between respective ends of the at least one fiber is greater than a dimension of the respective ends of the at least one fiber.

摘要： Dental appliances and methods for expanding the lower dental arch. The appliances may be removable mandibular expander devices for efficient arch expansion while being comfortable to wear and easy to use. The appliances may include a lingual portion that is shaped and sized to apply an expansion force to lingual surfaces of one or more teeth. The shape and size of the lingual portion may be configured to distribute the forces among posterior and/or anterior teeth. A series of expander devices may be designed to provide the expansion forces in a stepwise fashion toward a target lower arch configuration according to a treatment plan
