  • Patent number: 12005239
    Abstract: A new type of syringe for delivering composite material for direct application of the material in the mouth of a patient. The new type of syringe includes a threaded screw for driving a piston through the syringe in order to extrude the material from the end of the syringe. The extrusion force is thus generated in the syringe, thereby allowing for a simpler, less costly motorised driving system using a torque driving movement. The syringe also includes a localised heating arrangement at the extrusion end.

  • Patent number: 9452027
    Abstract: A vibrating applicator is provided for applying a dental composite material onto a tooth. The applicator has an elongated body and a tip that is coupled to the elongated body to apply the dental composite material onto the tooth. The applicator further has a vibrating apparatus for vibrating the tip and a sensor for sensing a condition of the dental composite material. A controller is operatively coupled to the vibrating apparatus and to the sensor and is configured to automatically vary an output frequency of the vibrating apparatus in response to the condition sensed by the sensor.

  • Patent number: 8992224
    Abstract: The method of curing a dental composite includes forming a composite filling in a cavity of a tooth surface by filling the cavity with an uncured composite and determining the geometry of the composite filling, including locations of interfaces between the composite filling and the tooth surface. The method further includes calculating a predetermined polymerization pattern for minimizing shrinkage stress at the interfaces, based on the geometry of the composite filling, and scanning a focused laser beam across the composite filling in accordance with the predetermined polymerization pattern to selectively and progressively cure the composite filling.

  • Publication number: 20140106297
    Abstract: A dental bur and method for removing a soft deposit from a tooth or an implant, the bur having a shank adapted to be connected to a rotary device. A head extends from the shank. The head has a material hardness adapted to remove soft deposits attached to the tooth but deflect against the tooth. Furthermore, the head is sized for insertion into a periodontal pocket adjacent to the tooth without surgery. Thus, the dental bur may be rotated against the tooth for removing the soft deposits but deflect and/or wear against the tooth for preventing damage to the tooth.

  • Patent number: 8518380
    Abstract: A prophylactic (prophy) paste composition comprising about 40 percent by weight to about 55 percent by weight expanded perlite comprising perlite granules in the range of about 20 ?m to about 70 ?m and floaters. The prophy paste composition further comprises no more than 5 percent by weight of a surfactant, and greater than about 10 percent by weight water. In some embodiments, the inventive paste also contains a humectant and optionally, may contain coloring agents, preservative agents, alcohol, flavoring agents, viscosity increasing agents, and sodium fluoride. The present invention also provides methods for controlling the floater content of the expanded perlite used in the inventive paste and methods of packaging the expanded perlite paste composition in a tube. The present invention also provides a prophy paste product comprising the inventive prophy paste contained within a squeezable tube.

  • Publication number: 20120202166
    Abstract: A vibrating dental instrument is provided that may be used with different styles of tips for performing different dental procedures. The dental instrument has an elongated body and a tip that is releasably coupled to the elongated body. The dental instrument further has a vibrating apparatus for vibrating the tip and a sensor for sensing a condition of a dental composite material when the tip is used to apply the dental composite material onto a tooth. A controller is operatively coupled to the vibrating apparatus and to the sensor and is configured to automatically vary an output frequency of the vibrating apparatus in response to the condition sensed by the sensor.

  • Patent number: 7648361
    Abstract: A dental dam clamp comprises first and second spaced, opposing jaws and respective first and second tooth engaging portions on the jaws. The first and second tooth engaging portions are positioned in confronting relation to one another and are biased toward one another by a resilient member when the jaws are moved outwardly from a free state defining a first position of the jaws. In one embodiment, first ends of the tooth engaging portions are spaced closer together than the second ends of the tooth engaging portions when the jaws are in the first position. The spacing between the first ends of the tooth engaging portions may be substantially the same as the spacing between the second ends of the tooth engaging portions when the jaws are moved outwardly to a second position. In another embodiment, the tooth engaging portions include friction-increasing surfaces to help secure the clamp to a tooth.
