  • Patent number: 10172688
    Abstract: According to various implementations, a dental cleaning device includes a steam conduit and a cooling fluid conduit. The steam conduit has a distal tip with an opening defined therein that allows steam to be applied intraorally close to a dental implant to flush away bacteria that has colonized on or adjacent the dental implant. The cooling fluid conduit has a distal tip with an opening defined therein that allows a cooling fluid to be applied intraorally close to the dental implant following the application of the steam to cool the tissue and prevent overheating of the tissue and bone adjacent the dental implant. For example, the cooling fluid may be applied intermittently with the steam, or the cooling fluid may be applied continuously while the steam is applied intermittently, according to various implementations.

  • Patent number: 10136974
    Abstract: Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated.

  • Patent number: 10136967
    Abstract: A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.

  • Patent number: 10136965
    Abstract: A customized orthodontic bracket system is provided. The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error in tooth positioning. The bracket slot can be configured to have a bracket slot width substantially matching a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.

  • Patent number: 10130443
    Abstract: A dental instrument is designed to help facilitate the procedure of root canal therapy and can reduce the inaccuracies that are accompanied with using traditional methods of attaching an electronic apex location (EAL) to an endodontic hand file. The endodontic hand file can include an exposed window in the handle of the file that holds an extension of the main body of the file. The clasp from the EAL can attach to this exposed metal in the window of the handle. This new location for attaching the EAL to the hand file can provide an accurate measurement while removing variables such as file movement in the canal, stopper thickness, clearance from the opposing tooth. The endodontic hand file with its exposed window provides a safe, reliable and accurate way of using an EAL to measure the root canal length.

  • Patent number: 10123860
    Abstract: A method employs a closed system mouthpiece using light and heat generation to activate a gel formulation to increase its volume. The gel formulation is coated into the mouthpiece, which is inserted into the user's mouth. Application of heat above a threshold temperature causes the gel to transform into foam and expand out of the mouthpiece and into the oral cavity. The mouthpiece creates a hermetic seal such that the foam expands out throughout the oral cavity into nooks and crannies that are normally difficult to access. Activation of a light source embedded within the mouthpiece enhances the bacteria killing properties of the foam material. The pH balance of the mouth is restored by the inventive method and apparatus to a neutral level in the range of 6.75 to 7.25.
