  • Patent number: 10660655
    Abstract: The present invention relates to a medical drill device. The medical drill device includes a boring drill including a motor and a drill part; an instrument body coupled to the boring drill; and a plurality of supporting rods coupled to the instrument body so as to support the boring drill to a work area. Each of the supporting rods includes: a straight portion inserted into the corresponding supporting rod insertable part in such a manner that the supporting rod is linearly moved with the instrument body; and a bent portion bent at a predetermined angle from the straight portion. As such, by using the supporting rods having a bent structure to support a boring drill to a work area and simultaneously limiting a boring depth of the boring drill, it is possible to shorten boring time and ensure safety of the boring operation.

  • Publication number: 20140272773
    Abstract: An image guidance system for tracking a surgical instrument within the oral cavity. The image guidance system includes a plurality of cameras adapted to be located within the oral cavity to provide intraoral images of optically visible patterns within oral cavity. A processing system receives and processes the intraoral images to recognize patterns and triangulate the locations and orientations of each camera. The processing system uses a reference dataset which defines a reference coordinate system based on alignment to a portion of the oral anatomy. The processing system determines the location and orientation of the tracked instrument based on the reference dataset. In an embodiment, the system includes an oral fixture that is removably attachable to teeth in a patient and is configured to hold one of the cameras.

  • Patent number: 8821158
    Abstract: The system creates digital images of teeth topography using a dental impression tray that provides registration information for integration of a digital three-dimensional model with a digital three-dimensional cranio-facial CAT scan record. The impression tray is held in the patient's mouth during a CAT scan. The tray includes fiduciary markers that can be accurately located by the CAT scan. The tray also includes a dental impression material which, subsequent to the CAT scan, is removed from the patient's mouth and placed on a table of an X-Y-Z scanning machine for scanning the impression. In this manner, a set of electronic data related to the patient's teeth and surrounding soft tissues is generated. The fiduciary markers, which may be constructed of titanium, are included in both sets of electronic data for the patient's teeth. The markers are then used as common reference points in the spatial matching of the two scans.

  • Patent number: 8764440
    Abstract: A drill guide uses a hole in a layer to guide a drill along an axial trajectory while permitting off-axis excursions of the drill during use. A number of such drill guides at varying heights from a target surface may be used sequentially or concurrently to enforce the axial trajectory in three dimensions during a surgical operation. A drill guide may include a hole in a layer that establishes a single point along the axial trajectory, or the drill guide may include multiple layers in a single device to establish two or more points along the trajectory while allowing off-axis insertion of a drill into the guide. The drill guide may be cuttable to accommodate intraoperative changes to the axial trajectory. In embodiments, a window or the like may be provided to permit a surgeon to view drill depth, drill orientation, the surgical site and the like during a procedure.

  • Patent number: 8734151
    Abstract: An apex-locating method and device for determining the depth position of the apex in a dental root canal. It uses a device making it possible to form a circuit including a first probe electrode inserted into the root canal of a tooth, a second electrode in conductive contact with an oral mucous membrane, frequency-generating elements able to produce alternating electrical signals at a number of frequencies, and elements for measuring electrical magnitude of alternating signals in the circuit. Provision is made for exciting the circuit and measuring the levels of magnitude of the alternating signals, respectively at low frequency and at high frequency and for detecting a point of intersection where the two levels measured at low and high frequencies meet and become substantially equal, these frequencies being sufficiently far apart for this point of intersection to exist. This point gives the position of the apex.

  • Patent number: 8662890
    Abstract: A method for manufacturing a dental restoration for at least one section of a dental arch on the basis of digital overall data which are calculated in relation to individual data, which are based on three-dimensional optical individual measurements that are performed intra-orally of an area that contains at least one section of the dental arch. In order to ensure that the overall data, which have been received from individual measurements, represent the measured section of the dental arch and/or the dental arch in its entirety without any distortions, it is proposed that at least one area of the dental arch be measured together with a reference, which supplies three-dimensional information, and calculated from the individual data while considering the reference of the overall data.
