    摘要: A system capable of performing radiography using a beam of electrons. Diffuser means receive a beam of electrons and diffuse the electrons before they enter first matching quadrupoles where the diffused electrons are focused prior to the diffused electrons entering an object. First imaging quadrupoles receive the focused diffused electrons after the focused diffused electrons have been scattered by the object for focusing the scattered electrons. Collimator means receive the scattered electrons and remove scattered electrons that have scattered to large angles. Second imaging quadrupoles receive the collimated scattered electrons and refocus the collimated scattered electrons and map the focused collimated scattered electrons to transverse locations on an image plane representative of the electrons' positions in the object.

    摘要: A gas bubble agitated mixing system for viscous fluids comprising: a container (1) in which a viscous fluid (2) may be held; one or more gas pipes (6), each gas pipe having an outlet (8) arranged to introduce gas bubbles (9) into the base region of the container (1), said gas bubbles (9) being of a size suitable to agitate the viscous fluid (2). The system also comprises a moveable carrier arm (4) upon which said one or more gas pipe outlets (8) are mounted; and wherein the movement of the carrier arm (4) causes the position at which each outlet (8) introduces gas bubbles (9) into the container (1) to vary over time.

    摘要: A direct dental bridge, built in the mouth of a patient, comprising Zirconium oxide or Aluminium oxide reinforcement bars (19, 20) onto which the pontic of the bridge is assembled. The ceramic bars of the present direct dental bridge bond better to dental filling materials and dental bonding resins than metal bars, and are easier to use than fiber ribbons and resin bars. Also disclosed is a method of building a direct dental bridge further comprising the use of a dental material gingival wedge bonded on an abutment tooth, demale molds for surface veneers, malleable gingival veneers and occlusal/buccal surface veneers.

    摘要: A reinforcement bar combination for a direct dental bridge, the reinforcement bar combination including: first and second elongate bars, each of the first and second elongate bars contacting a single occlusal preparation formed in a single abutment tooth and each of the first and second elongate bars having an end positioned on a central pad of a third elongate bar to form a reinforcement scaffold. The first elongate bar is a first elongate torque bar that is optionally bent. The second elongate bar is a second elongate torque bar that is optionally bent. The third elongate bar is a proximal bar including a central planar pad bound by a perimeter, a coronal facing surface and an apical facing surface, a first insertion arm extending in a mesial direction from the perimeter of the pad, a second insertion arm extending in a distal direction from the perimeter of the pad; a first vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad; a second vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad. A method of using of the reinforcement bar combination to produce a direct dental bridge is also described.

    摘要: Two new burs to be used in dentistry applications. The two burs are used one after the other to create a natural anatomy in restorations of teeth. One of the burs also reduces the need for anesthetic by providing for minimal contact with the dentin while removing the enamel when cutting into a tooth.
