During storage and subsequent use the composition in the storage chamber must be maintained segregated from the applicator surface. This is accomplished by delivering the peroxide containing tooth whitening composition from the storage chamber through a delivery channel having a length and a cross-sectional diameter sufficient to preclude the migration of moisture and the enzyme catalase from the application surface to the storage chamber. The composition is applied to teeth by means of bristles, a sponge surface or fibrillated surface. This applicator can be used with both aqueous and non-aqueous peroxide containing tooth whitening compositions.

  • Patent number: 8834158
    Abstract: A screw syringe having a piston spindle with an external thread, a syringe barrel, having a sleeve with a piston end, and a female part with an internal thread is disclosed. The female part slides onto the piston end. The female part has a flange that creates a form fit with a counter-surface at the piston end so axial displacement of the female part in relation to the syringe barrel in the discharge direction is prevented. The female part has retaining surfaces that create a form fit with counter-retaining surfaces of the piston end, thereby preventing axial displacement of the female part in relation to the syringe barrel counter to the discharge direction. The retaining surfaces and counter-retaining surfaces create a form fit that prevents radial relative movement between the retaining surfaces and the counter-retaining surfaces, directed perpendicularly to the sliding direction.

    Abstract: A composite capsule for receiving and dispensing a dental compound. The composite capsule has a receiving space, which is surrounded by a capsule wall and which extends between a discharge opening and a receiving opening, wherein the discharge opening is arranged at a front end of the receiving space, and the receiving opening is arranged at a rear end of the receiving space. The composite capsule comprises a support face, which protrudes outward in relation to the capsule wall and which is oriented in the direction of the front end. The support face is interrupted by a thread recess. By way of the thread recess, the composite capsule can be connected to a storage container, in order to introduce a desired amount of dental compound into the composite capsule.

  • Publication number: 20140170594
    Abstract: A carpule for a dental syringe provides an internal piston disposed between a front septum and a rear plunger. The internal piston is hollow and includes a thin membrane front. The internal piston is designed to offer minimum resistance to movement in the carpule body to allow for aspiration and for easy dispensing. The internal piston divides the carpule into two anesthetic chambers, allowing an anesthetic without a vasoconstrictor and an anesthetic with a vasoconstrictor to be dispensed sequentially in a single injection and without causing undue trauma to the patient.

  • Publication number: 20140106299
    Abstract: A dispensing device for a dental material comprises a cartridge having an outlet nozzle which forms a passageway for the dental material. The dispensing device further comprises a closure which is placeable on the outlet nozzle for sealing the cartridge. The closure comprises a pin for extending into the passageway, and is further adapted to seal with an outer surface of the outlet nozzle. The dispensing device is further adapted such that the pin is displaceable from the passageway by dental material dispensed from the cartridge, wherein the displacement causes the closure to release from the outlet nozzle. The invention may provide for relatively easy operation of the dental dispensing device.

  • 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: 8651861
    Abstract: A sulcus impression tip for injecting dental impression material for making dental impressions. The tip includes a body having a gripping portion and a discharge tip having a bore there through which permits a friction fit with the outside diameter of needle cannula. The needle cannula extends approximately 2 millimeters past a distal end of the discharge tip. The body further defines an angle for holding the gripping portion to permit the discharge tip and needle cannula to be positioned for easy access in the oral cavity by the dentist. The discharge tip is sized and shaped to separate the gum from the tooth in the selected region so that the needle cannula is positioned to permit exact positioning for placement of the dental impression material along the sulcus.

  • Publication number: 20140034670
    Abstract: A container 10 for mixing and dispensing of material having a liquid receptacle 14 and a plunger 18. The receptacle 14 has a front portion 36 and the plunger 18 has a forwardly projecting sharp protrusion 42 having a shaft 72 which terminates in a sharp outer end 78, 82. Upon the plunger 18 being depressed the sharp protrusion 42 pierces a front portion 36 of the liquid receptacle 14 and liquid in the receptacle 14 is pushed hydraulically through the front portion 36 into a main chamber 17. Thus the liquid contacts material in the main chamber 17 to form a mixture. The plunger 18 can continue to be depressed so as to break the front portion 36 of the liquid receptacle 14 away and then push the material in the main chamber 17 towards a dispensing nozzle 26. The main chamber 17 has a frangible membrane 22 at a distal end 13 thereof which is hydraulically broken by pressure applied from the material in the main chamber 17 so that the material can be dispensed from the container 10.
