  • Patent number: 10014744
    Abstract: The present invention relates to a direct cooling type handpiece, and more particularly, to a direct cooling type handpiece that is configured to allow an outer housing and a core to be spaced apart from each other and thus to allow the core to be fixed to a PCB and a support cap, so that air flows to the space between the outer housing and the core, thus efficiently cooling the high heat generated from the handpiece while the handpiece is being operated.

  • Patent number: 9883931
    Abstract: The present invention relates to a device and a method for the application of composites in tooth cavities. The device consists of a spray gun with integrated lighting for light-polymerizable composites, a measuring unit and a control unit. The composites are applied under controlled, precisely dosed exposure to polymerization light. According to the invention, the composite initially runs onto the walls of the cavity or onto previously introduced filling material and then, as a result of the light exposure, is transformed into the gel state. Thus, a large part of the polymerization shrinkage of the composite occurs while the composite is still plastically deformable so that any formation of gaps is compensated by the composite continuing to flow. It is only at this point in time that a sufficiently high dosage of light is applied for complete curing to occur.

  • Patent number: 9611500
    Abstract: A method and apparatus for detecting the presence of the viable cells in an endodontic sample in or taken from an endodontic cavity in the tooth, such as the root canal, enables the rapid and low cost identification of the presence or absence of bacteria or other viable cell tissue in the endodontic space by first incubating a viable cell indicator with an endodontic sample for a pre-determined period suitable for chair-side test and then measuring and/or detecting a change in a parameter (e.g. fluorescence) associated with the viable cell indicator. Thereby, the required level of root canal treatment can be reached which minimizes the risk of re-infection without the time, cost and potentially harm of over-preparation and over treatment by the dental surgeon or of a re-treatment.

  • Patent number: 9248006
    Abstract: The method and extractor relate to dentistry and are intended for extraction of metal instruments fragments from a root canal of the tooth, as these instruments may be broken and may get stuck here, for example, during endodontic treatment. According to the invention, two insulated metal electrodes assembled as a cylinder are inserted into the root canal until electric contact with the fragment to be extracted. Then electric current impulse is ran through the circuit formed by the first electrode, metal fragment and second electrode; the intensity and duration of the electric impulse shall be sufficient for welding of the fragment to the electrodes by means of heating at the contact points; this time a heating of the surrounding tissues remains at the physiologically acceptable level; afterwards the electrodes are extracted from the root canal together with the fragment. Depending on a clinical situation, electrodes of various size and configuration are used.

    Abstract: A delivery device for delivering filling material into the canal during a root canal procedure comprises a shaft having a bed portion at a distal end thereof, and a biocompatible filler material mounted to the bed portion. The filler material comprises an upper surface, a side surface, and a distal end. The delivery device bed portion has a greater thermal conductivity than the filler material; and the bed portion of the shaft wraps at least partially around the filler material and contacts the filler material substantially along the length of the filler material from the upper end of the filler material to at, or proximate, the distal end of the filler material. This delivery device allows for better control of temperature delivery and position of the filling material and allows for a more thorough and precise heating of the filler material in vivo.

  • Patent number: 8403664
    Abstract: A dental obturation system, which is configured such that a power terminal unit is installed between a rotary unit and a cartridge unit such that a heating unit can heat a filling material and a needle member, mounted to the front end of a main body having a battery therein, can be rotated while applying the heated filling material to a root canal, so that an operator can easily and conveniently administer dental treatment without changing his/her posture or the orientation of the main body according to the location of a decayed tooth of a patient.

  • Patent number: 8387467
    Abstract: A method for testing a coating for blade roots, includes: providing a disk test piece including at least one bearing surface and a blade test piece including at least one bearing surface coated with the coating to be tested, the blade test piece including two test piece halves adapted to be engaged on either side of the disk test piece, and subjecting the blade test piece engaged with the disk test piece to tensile cycles during which the test pieces undergo tensile stress with respect to each other in a tensile direction, the tensile strain being transmitted via the bearing surfaces contacting the blade test piece and the disk test piece. The method allows for very faithful reproduction of the behavior and ageing of the coating and thus allows for accurate evaluation of the quality of the coatings.

  • Patent number: 8371853
    Abstract: A mouthpiece that adjusts manually in the mouth and seals the treatment area. It includes light emitters and heat generators. Textured bands guide and direct light to diffuse evenly. A seal bead seals the gum above the teeth. For whitening, a whitening gel is first applied to the user's teeth, the mouthpiece is then positioned in the user's mouth, and the seal bead seals against the user's gums. Then, the light emitter(s) and heat generator(s) are activated to effect the whitening while causing an increase in the temperature enabling the user to mold the mouthpiece to their mouth.
