  • Publication number: 20140212835
    Abstract: An In-situ Tooth Filling System and Method Utilizing External Curing Step. The method and system utilizes the heat-/light-/vacuum-curing process normally available only in a dental laboratory. Like the conventional dental prosthetic production process, the filling is attached to the tooth void utilizing curable cement. Unlike the conventional (indirect) method, however, the instant method is completed totally within a single appointment in the dentist's office. The system utilizes fill stems that are made from curable filling material. These stems will become a part of the filling when the filling is cured. The filling is partially cured and then removed from the tooth for final curing in a vacuum oven that heat- and/or light-cures the filling.

  • Patent number: 8758010
    Abstract: A dental clinical apparatus having a function which conventional instruments for dental treatment have not had and having a novel constitution. The dental clinical apparatus includes a syringe which has a fluid jetting system for dental treatment and a plasma jet applying means for producing a plasma jet from the end by allowing a low-frequency high-voltage power supply to apply a low-frequency high voltage between electrodes on the outer peripheral surface of a rare gas tube through which a rare gas having a low dielectric breakdown voltage under the atmospheric pressure is flowed, and thereby causing electrical discharge.

  • Patent number: 8753117
    Abstract: The appliance (10, FIG. 1) includes a body portion (27) and a nozzle portion (30) through which a spray of liquid droplets exits from a distal end thereof for cleaning of dental regions. The nozzle includes an orifice (36) at a proximal end thereof adjacent the body portion, as well as a pump (38) for moving liquid into an area of the nozzle just forward of the orifice. A mechanical system (12, 13, 14) is provided for moving a plunger or piston element (16) first away from the orifice under tension, such as a compression spring (24), and then controllably releasing the plunger or piston toward the orifice, the plunger/piston moving with sufficient force that atmospheric air which has been drawn into the appliance between the plunger or piston is forced through the orifice at a sufficiently high rate of speed to produce a spray of fluid droplets for dental cleaning when the moving air comes into contact with the liquid in the nozzle.

  • Patent number: 8696609
    Abstract: A multi-switch (24) for an oral care appliance includes a switch housing (28) having a hollow chamber (30) therein, a button actuator (32) with at least two O-rings (42) around the periphery thereof, and inlet and outlet channels (50, 52) connecting a source of compressed gas (18) with the housing chamber and the housing chamber with a mixing chamber (26), respectively. A pump (60) moves fluid from a reservoir (20) to the mixing chamber. The O-rings are positioned so that as the button actuator is actuated and then released, the outlet is closed and the inlet is opened, allowing gas to move into the housing chamber. The pump is actuated, and then the inlet is closed and the outlet opens, allowing gas in the chamber to move to the mixing chamber to produce a stream of fluid droplets, which are directed out through a nozzle portion (16) of the appliance.

  • Patent number: 8690570
    Abstract: A container (10) for mixing and dispensing material comprising a body (12) having a main chamber (17), a dispensing nozzle (26), a liquid receptacle (14) and a plunger (18). The liquid receptacle (14) has a side wall (37) and a front wall portion (36) which is caused to break away from the side wall under pressure being applied by a plunger (18) so that the plunger and front wall portion can traverse the entire length of the body (12). This enables a charge of material in the main chamber (17) to be dispensed through a frangible wall or membrane (22) into the nozzle (26). The container 10 has a compression zone with a stepped region (50) for providing limited resistance to movement of the plunger and broken away end wall for use with low viscosity material for reducing the risk of uncontrolled extrusion of low viscosity material.

  • Patent number: 8616879
    Abstract: A material capsule containing a reactive or caustic dental material and a separately attachable delivery tip having a metal cannula. A material capsule for placement in a syringe contains a reactive or caustic dental material for dispensing through a metal cannula. The material capsule is sealed for storing the caustic or reactive dental material, preventing prolonged contact with or proximity to the metal cannula of a delivery tip. Contact with the reactive or caustic dental material only occurs during actual dispensing. Transition portions facilitate dispensing of viscous material. External grips facilitate attachment of the delivery tip. The dispensing and accurate placement of caustic or reactive dental materials is facilitated, making dentistry easier.
