  • Patent number: 10646119
    Abstract: A plaque detection system is presented including a dental implement and a multi-mode optical waveguide for receiving fluorescence light from a plurality of angles, the fluorescence light traveling along a core of the multimode optical waveguide at different path lengths resulting in modal dispersion. The plaque detection system also includes a detector configured to receive the fluorescence light for detecting plaque, calculus, and/or caries, and communicating plaque identification information of teeth based on frequency domain lifetime measurements. The modal dispersion is used to detect at least one plaque, calculus, and or caries fluorescence area on the teeth. The plaque fluorescence area detected with modal dispersion includes different levels of plaque with respect to a center point of the plaque fluorescence area. Thus, a plaque detection signal depends on a radial distance from the center point of the plaque fluorescence area.

  • Patent number: 10524879
    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: 10478270
    Abstract: An oral appliance that attaches to molars or bicuspids and that combines the capability for side-to-side and front-to-back expansion and contraction in one unit as a self-stopping mechanism. Further, this embodiment can be activated to compress or expand and be deactivated in two planes of side-to-side or front-to-back, along three different arms/bridges respectively. This is to say that one arm can compress front-to-back while the other arm expands, the jaw/teeth front-to-back, simultaneously). With proper arrangements and anchorage preparation the device shown and described can move front teeth forward or backward or back teeth forward or backward independently on either side of the mouth.
