  • Patent number: 8398394
    Abstract: A system for driving an electric handpiece in response to a pneumatic control signal may provide for fast interchange of handpieces, self-calibration and wide dynamic range of operation with precise speed control. The system may be incorporated into virtually any dental treatment center using traditional pneumatic drive handpieces, and a conversion kit may facilitate such conversion. The system may provide not only for controlling the speed and torque of a tool coupled to an electric drive handpiece responsive to a pneumatic control signal, it may also provide for coupling cooling air and treatment media, such as air and/or water to the handpiece. Coupling of a handpiece to an operating base of the system, including coupling of media lines and electrical connections may be made with a simple press and twist action using quick connection structure.

  • Patent number: 8348669
    Abstract: A method is set forth for making a computer model of patient's jaws, face, teeth and removable dentures on the basis of digital information. Three dimensional digital data about the soft tissues, artificial teeth, supporting bone and position of nerves is combined in a virtual computer model to create an aesthetic and functional plan for the creation of surgical drill guides and the creation of new dentures and teeth. A key component of this method, the accurate positioning of dental casts in a physical articulator, is simplified using three dimensional virtual and physical measurements and movements. Surgical guides used to position dental implants are manufactured using computer milling, layered manufacturing or conventional laboratory techniques with the aid of mechanical tools that reproduce the position of the dental cast or digitally produced replica in the same orientation to the virtual implant position.

  • Patent number: 8349009
    Abstract: An implant that includes titanium and has one or more surfaces which can be applied in or on a bone growth area. One or more of the surfaces are arranged with a depot for bone-growth-initiating or bone-growth-stimulating substance, in which the depot is formed by a pore arrangement in a relatively thick oxide layer on the titanium. The substance is acted on, for a considerable period of time, by one or more release functions for the substance which permit a controlled or optimized release of substance to the surrounding tissue or bone growth area.

  • Patent number: 8337203
    Abstract: A mobile suction unit preferably includes a portable body, a deformably non-resilient appendage connected to the body, and a dental instrument connected to the deformably non-resilient appendage. The deformably non-resilient appendage may be selectively bent from a non-tensioned shape to a curvilinear tensioned shape in such a manner that the deformably non-resilient appendage indefinitely retains the curvilinear tensioned shape while the dental instrument is adapted to be positioned within the patient oral cavity.

  • Patent number: 8297970
    Abstract: The orthodontic bracket according to the present invention is provided with ligating means having a simple configuration, has additional functions for improving therapeutic effect and improving aesthetic appearance and enables maintenance to be carried out easily. A movable slider portion 2 for pinching an upper portion and a lower portion of an archwire to hold the archwire is provided in order to hold the archwire with respect to a bracket body 1 that has a slot 5 for holding the archwire. This slider portion 2 is inserted into the bracket body 1 to thereby hold the archwire 6. An orthodontic bracket composed of the bracket body 1 and the slider portion 2 has aesthetic properties by having a rounded shape with few surface irregularities. The slider portion 2 can be readily moved with an operating tool 14 and can be easily attached and detached.

  • Patent number: 8292623
    Abstract: Systems and methods for setting posterior prosthetic teeth in production of upper and lower dentures feature tooth blocks each having inner and outer bodies having upper and lower rows of recesses therein corresponding maxillary and mandibular prosthetic teeth. The recesses of the inner and outer bodies conform to lingual and buccul surfaces of the prosthetic teeth respectively and are shaped and positioned to establish proper positioning of the prosthetic teeth relative to one another when clamped between the bodies. The two tooth blocks accommodate respective ones of left and right prosthetic poster teeth sets. Connection elements between the tooth blocks allow adjustment and subsequent locking of the relative positioning between the left and right teeth sets before setting on mandibular and maxillary casts in an articulator. The two tooth blocks eliminate the need to individually position posterior teeth on each side of the jaw.

  • Patent number: 8277216
    Abstract: A dental impression tray assembly includes an upper tray and a lower tray operable with the upper tray, and the lower tray includes a first piece configured to measure jaw relations of a patient's mouth and a pair of second pieces detachably attachable to the first piece. The first piece of the lower tray is inserted into the patient's mouth independently of the pair of second pieces of the lower tray to measure the jaw relations and to obtain a bite registration. After the first piece is connected to the pair of second pieces, the assembly allows a final gum impression of the patient's lower gum to be obtained.

  • Patent number: 8246352
    Abstract: Provided is a surgical guide that enables a dentist to visually identify the tip of a drill during dental implant treatment, and does not allow the drill to tilt more than necessary, and enables sufficient cooling water to be provided so as not to cause bone burns, and is compatible with several different types of drills having different diameters. A first wire is embedded in a mockup in a same orientation as the orientation of a fixture of an implant is to be embedded. A guide member of a surgical guide is fitted to a tooth portion of the mockup. An adjusting mechanism adjusts such that an intersection line made by plane-shaped red laser light beam and green laser light beam from line laser modules is located on the first wire. The guide member is removed from the tooth portion of the mockup, and fitted to a tooth portion in the mouth, and the orientation of a drill is aligned with the intersection line. Drilling operation is performed in the aligned condition.
