  • Publication number: 20190201296
    Abstract: Disclosed herein are aqueous dental coating compositions and methods for enhancing contrast of intraoral surfaces for 3-dimensional digital scanning. The compositions include: an aqueous solvent system; a water soluble polymer present at no greater than 5 wt. %, based on the total weight of the aqueous dental coating composition; hydrophilic particles; and hydrophobic particles, wherein the aqueous dental coating composition is a dispersion or a dispersion of the hydrophilic particles and hydrophobic particles in the aqueous solvent system can be formed by shaking the composition for 30 seconds.

  • Publication number: 20190183374
    Abstract: In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.

  • Publication number: 20190153878
    Abstract: The present disclosure provides methods and systems for the bonding of dissimilar substrates. For example, a first substrate may be coupled to a second substrate by a composite joint between the first substrate and the second substrate. The composite joint may be comprised of a first adhesive material and a second adhesive material. The first adhesive material may be disposed on the first substrate, and the second adhesive material may be disposed to the first adhesive material. The composite joint between the first substrate and the second substrate may provide an isolation layer therebetween, preventing galvanic corrosion.

  • Publication number: 20190083208
    Abstract: In some examples, a tool for forming a dental restoration comprises a preformed mold body configured to provide a patient-specific, customized fit with at least one tooth to be restored of a patient. The mold body is configured to align with a portion of a surface of the at least one tooth, and is configured to combine with the at least one tooth to define a mold cavity encompassing at least a portion of desired tooth structure of the at least one tooth to be restored of the patient. The portion of desired tooth structure defines a transition from a supragingival surface of the at least one tooth to a subgingival surface of the at least one tooth.

  • Publication number: 20180098828
    Abstract: An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.

  • Publication number: 20140154637
    Abstract: Provided are customized archwires that facilitate wire insertion into fixed appliances and sliding mechanics during the course of orthodontic treatment. These archwires are harmonized with lingual appliances by modifying the archwire shape to alleviate the adverse effects of bends and archwire length discrepancy while maintaining the overall archwire shape. This in turn can be accomplished by selecting one or more segments of an archwire shape from a library, strategically adjusting arch length, performing morphing or smoothing operations on a wire configuration intended for final occlusion, and combinations thereof.
