  • Patent number: 10420631
    Abstract: Apparatus, system, and methods for utilizing one or more computing devices to stage the movement of teeth during an alignment treatment are disclosed. The computing device receives an electronic representation of the patient's teeth in their initial position and an electronic representation of the teeth a final position for each tooth. A route each tooth will travel to reach its final position is determined, and the teeth are scheduled to move according to a movement pattern. Moreover, the schedule of movement takes into account a maximum rate of tooth movement for each tooth, the path of movement for each tooth, the distance each tooth needs to move, any needed tooth staggering, any needed round-tripping or tooth movement slowing. The invention also includes techniques for determining an optimum number of stages for the treatment based on the schedule of movement.

  • Patent number: 10336102
    Abstract: Provided herein are methods of obtaining good photocured-ink adhesion to low surface energy materials. The methods have greatly improved adhesion of photocured ink on low surface energy materials, including those that are subjected to high humidity or wet environments. The methods take into account the glass transition temperature (Tg) of the materials and the onset for the glass transition temperature, including ink applied to an exposed surface of the material at an elevated temperature that is close to the Tg of the material. The ink is allowed to sit briefly or soak, such as for more than 1 second, before the ink is cured. The ink may be photocured. Furthermore, the methods do not require solvents or surface treatment, including plasma or corona treatments, to obtain good ink adhesion.
