  • Patent number: 11622835
    Abstract: A method of endodontic therapy with improved disinfection and ablation characteristics may feature the use of an alcohol or polyol-based indocyanine green (ICG) solution with a laser system that emits a wavelength within the maximal absorption range of ICG. By matching the dye and laser output, radiant energy use is maximized for efficient ablation and disinfection of treated tissues. Also, the use of an alcohol or polyol as a solvent for the ICG solution increases the inherent disinfection qualities of the solution itself. In one embodiment, the prepared canal is flooded with the ICG solution and the laser activates with the laser fiber inserted into the solution. In an alternate embodiment, the solution is mostly removed prior to activation of the laser, but only after necrotic tissue has been stained.

    Abstract: An augmented reality/mixed reality system that provides an immersive user experience. That experience is provided with increased speed of update with low computational resources for occlusion data representing a user's hand that can be used to occlude virtual objects. The hand occlusion data are generated by computing a hand mesh from live depth sensor data. A small amount of data is processed by masking live depth data with a model in which a hand is simply represented by multiple segments identified from key-points. The hand occlusion data may be generated by predicting changes in a hand pose between a time of capture of the depth data and the time when the hand mesh will be used for occlusion processing. The hand mesh may be distorted to represent the hand in the predicted pose.

  • Patent number: 11517400
    Abstract: A method and a system for determining an orthodontic treatment plan including a tooth stripping step are provided. The method comprises: acquiring a 3D digital model of a first tooth and a second tooth of the subject, the second tooth being adjacent the first tooth; receiving a stripping request for stripping tooth material, from at least one of the first tooth along a first stripping plane and the second tooth along a second stripping plane; determining, along a surface of the first tooth, a first area of interest; determining, along the surface of the second tooth, a second area of interest; determining a distance between a first set of vertices associated with the first area of interest and a second set of vertices associated with the second area of interest; in response to the distance being greater than a predetermined distance threshold, denying, by the processor, the stripping request.

  • Patent number: 11517762
    Abstract: An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece comprises a lamp support structure comprising a lamp support surface and is formed of a first material. A flexible lamp is mounted to the lamp support surface so that a light emitting surface of the flexible lamp assumes a concave curvature, thereby forming a lamp assembly. A guard component is overmolded to the lamp assembly. In one embodiment, the oral treatment device may be a teeth whitening device.

  • Patent number: 11497587
    Abstract: The present invention discloses an oral scanner, including an outer casing, a reflector, a heat source, an optical module and a forced convection element. The outer casing has a cavity. The reflector is located at the front end of the cavity. The heat source is located in the outer casing. The optical module is located in the casing. A heat channel is formed between the optical module and the outer casing. The forced convection element is disposed in the heat channel and configured to forcedly dissipate the waste heat of the heat source to the cavity to heat the reflector. Thus, the temperature of the heat source can be reduced, and vapor will not be generated on the reflector heated by the waste heat.

  • Patent number: 11471980
    Abstract: The disclosure relates to methods and systems incorporating physical modeling to identify the ultrafast laser/material interaction mechanisms and the impact of laser parameters, to optimize implementation of ultrafast laser-based processing for a given material. The process determines a laser fluence near the ablation threshold for a given material and given pulse duration. The repetition rate, scanning speed and scanning strategy are subsequently optimized to minimize heat accumulation, having an operable line scan overlap between 50% to 85% for achieving smooth ultrafast-laser polishing, while maintaining an optic-quality surface.

  • Patent number: 11439482
    Abstract: An intraoral scanner includes a casing, a light source disposed in the casing, a reflection plate obliquely disposed in the casing for reflecting light of the light source to an object to be scanned through an opening of the casing, a transparent plate, and a receiver adjacent to the light source. A projection optical axis of the light source forms a first oblique angle with a receiving optical axis of the receiver. The receiver receives light after being incident to the object to be scanned and then reflected to the receiver by the reflection plate. The transparent plate is disposed between the light source and the reflection plate or covers the opening. The projection optical axis forms a second oblique angle with a norm of the transparent plate to make a reflection angle range of light reflected by the transparent plate fall outside a receiving angel range of the receiver.

  • Patent number: 11399926
    Abstract: The invention relates to a mouthpiece for performing a treatment of teeth such as teeth whitening. Accordingly, the mouthpiece may be arranged for cosmetic treatment. The treatment is based on illumination of the teeth of light with a suitable wavelength. The mouthpiece is designed so that light from light sources, e.g. LED's, is sufficiently homogenized so that the light irradiance at the teeth is sufficiently uniform to achieve good treatment results. Furthermore, the mouthpiece is designed so that the irradiance at the teeth is sufficiently high to achieve efficient treatment and so that heating of the teeth is minimized to an acceptable heating.

  • Patent number: 11361524
    Abstract: The quality of digital impressions geometry and color but also fluorescence, transillumination, reflection and absorption properties can be inferior to single frame 2D/3D images e.g. due to averaging effects, rendering effects, difficult scanning situation etc. This can lead to difficulties in the dental workflow such as the creation of a preparation margin line or detection of diseases such as caries. By providing a correlated view of high-quality single frame images and corresponding 3D models, the dental workflow can be guided to be completed more efficiently using the single frame images.
