The collision detection model may be based on an empirical data training for the flexible manipulator that includes training sensor data from the sensor and training image data of positions of the flexible manipulator. The processing circuitry may be configured to control the user output device based on the collision likelihood score to provide a collision alert sensory output to the user.

  • Patent number: 11344385
    Abstract: A set of primer appliances and a set of treatment appliances to be worn by a subject are provided. The primer appliances are first worn to prepare the local environment of the teeth for further repositioning of the teeth by the treatment appliances. The primer appliances may apply compression to the periodontal ligament, in a direction favorable for achieving the desired final position of a tooth. The compression may generate a biological response in the local environment of the teeth. The primer appliances may cause minimal or no repositioning of the teeth. The treatment appliances are worn to reposition the teeth from an initial position to an end position of a treatment stage. The primer appliances can improve the efficiency and accuracy of tooth movement by the treatment appliances.

  • Patent number: 11331164
    Abstract: Method and/or apparatus embodiments can provide a virtual orthodontic base, adapted to each virtual 3D dental model of the teeth (e.g., upper and lower jaw). The virtual orthodontic base should match each 3D model (e.g., size), conform to prescribed dimensional requirements and still be rapidly calculated. The 3D virtual teeth model can be provided or reconstructed (e.g., from a laser scanning, intra oral camera scanning or x-ray scan of a plaster, a negative impression (e.g., alginate or silicon) of a patient's dentition or directly from the patient's mouth).

  • Patent number: 11328814
    Abstract: Systems and methods for conducting intraoral scans of a mouth of a user include conducting, using an intraoral scanner at an intraoral scanning site, an intraoral scan of a mouth of a user based on determining that one or more teeth of the user are not being repositioned according to an initial treatment plan designed to reposition the one or more teeth of the user using a first plurality of aligners. The intraoral scan generates three-dimensional data of the mouth of the user. A corrective treatment plan is generated by a treatment plan computing system based on the three-dimensional data. A second plurality of aligners are produced at a fabrication site based on the corrective treatment plan. The second plurality of aligners are specific to the user and configured to reposition the teeth of the user according to the corrective treatment plan.

  • Patent number: 11288792
    Abstract: One embodiment can provide a system for detecting a difference between a physical object and a reference model corresponding to the physical object. During operation, the system obtains a real-world image of the physical object and generates an augmented reality (AR) image by projecting a three-dimensional overlay generated from the reference model onto the physical object in the real-world image. While generating the AR image, the system aligns a pose of the reference model to a pose of the physical object. The system can detect the difference between the physical object and the reference model based on the generated AR image and the real-world image.
