  • Patent number: 10251727
    Abstract: A method and system for producing a dental implant surgical guide is disclosed. A patient-specific virtual model is generated using image data specific to a patient and virtual dental implants. The virtual model aligns the image data with the virtual dental implants using modeling software. A virtual mold is generated from the virtual model, and a physical mold is generated from the virtual mold. The physical mold is covered with a thermoplastic sheet via a thermoforming process. Excess thermoplastic material is trimmed off after the thermoforming process to produce a thermoformed piece. Metal tubes corresponding to each the virtual dental implants are placed onto the physical mold denoting the position, trajectory, and depth of the one or more virtual dental implants. A dental implant surgical guide that contains the thermoformed piece with the one or more tubes is produced.

  • Patent number: 10195007
    Abstract: A drill burr includes a channel, extending along a longitudinal axis of the drill burr, and fluidically connected to a water reservoir for providing a constant-flow liquid jet. The constant-flow liquid jet has a first pressure directed at the bone along the longitudinal axis of the drill burr. A pressure sensor senses a pressure change in the liquid jet from the first pressure to a second pressure. A signal processing unit is configured to translate the pressure change into information indicating a structural change in the bone along the drilling path, from a first structure to a second structure, corresponding respectively to the first pressure and the second pressure. Optionally, the signal processing unit generates an audio alarm notifying of the structural changes.

  • Patent number: 10179035
    Abstract: Direct 3D-printed orthodontic aligners with torque, rotation, and full-control anchors are provided. In an implementation, an orthodontic system uses 3D-printed aligners to perform orthodontic treatment of teeth. Manufacturing the aligners by 3D-printing or additive manufacturing processes imparts novel geometries to the aligners for applying torque, rotation, and full 3D control forces to the teeth in novel ways. The 3D-printed aligners may contain multiple different plastic or metal materials with different orthodontic properties. In an implementation, divot anchors can be strategically applied to teeth to work in conjunction with a 3D-printed aligner fitted over the divot anchors and teeth. The divot anchors may include a depression, channel, groove, or notch providing an attachment point for the aligner to apply a force to the tooth through the divot anchor, such as a torque, rotational force, leverage, push, pull, or 3D control force.

  • Patent number: 10172689
    Abstract: A pulp chamber dental spacer constructed of cold water soluble material, which may include portions of polyvinyl alcohol, to protect the pupal floor of a pulp chamber from a drilled hole following a root canal treatment or procedure. The spacer may be spherical or cubical in shape and that protects the pupal floor by providing a solid “space” for a practitioner to feel the end of a temporary filing such that the drill does not descend to and possibly damage the sensitive pupal floor. The dissolvable material preferably is non-linting, thereby providing for complete removal and preventing the “wicking” of contaminated salivary fluids and causing coronal damage.
