摘要： A dispensing cartridge for use with a hand-held applicator has a chamber with a first section and a second section. The second section has a smaller cross-sectional area than the first section such that the chamber has a stepped configuration. A piston is slidably received in the chamber and has a head portion that is received in the second section and a tail portion that is received in the first section. As a force is applied to the tail portion, the head portion advances to expel material through an outlet opening. The cartridge is especially useful for dispensing compositions having a relatively high viscosity such as dental pastes and the like.

摘要： A system and method for storing in bulk and readily dispensing a dental composition includes a prefilled bulk storage syringe, storage container, or squeezable tube that is capable of storing multiple doses of the composition for dispensing into a dose administration syringe. The discharge end of the bulk storage syringe, storage container, or squeezable tube can be coupled directly to the discharge end of the dose administration syringe without an adaptor, allowing the dental composition to be readily transferred directly to the dose administration syringe. The dental composition can then be readily administered to a desired area from the dose administration syringe after the bulk storage syringe, storage container, or squeezable tube has been decoupled therefrom.

摘要： Special tools and materials are provided for the fitting and placement of artificial crowns and inlays in a patient's mouth. One version of the kit comprises test ribbons, ribbon gripping forceps, crown gripping forceps, a crown placement tool, an adhesive dispenser, expendable adhesive, an adhesive dispenser stand, an inlay/veneer placement tool, and a number of plastic or metal shims.The inlay placement tool is fitted with hot-melt adhesive on its tip for fixed attachment of an inlay or veneer for placement in the mouth. The crown placement tool is adhered with hot melt adhesive to the biting surface of a posterior crown to be used as a crown placing device.The ribbon forceps is used to grip a thin precut test ribbon and hold the ribbon in the patient's mouth vertically on either the front or back side of an artificial crown being placed. The crown placement tool is used to position an artificial crown in the patient's mouth onto the prepared tooth alongside the test-ribbon, whereby withdrawing the test ribbon with the ribbon forceps tests and marks the area of interproximal contact of the crown or inlay as well as the amount of pressure of the contact. The crown gripping forceps is also used to place an artificial crown for final cementation. The adhesive is not only used to place and remove an artificial crown or inlay for fitting, but is also used for the patient to bite on during cementation to keep the crown or inlay seated.

摘要： An apparatus for applying coatings to various surface types. The apparatus includes a dispenser for holding a quantity of the coating material and a delivery tip having adjustable bristles at one end. The bristles are slidably secured in a spiral passageway formed by a helical ridge inside the delivery tip, thereby allowing the coating material to be continuously applied without the need to stop the procedure and rewet the applicator. The applicator permits accurate control of the amount of coating material applied to the surface. In this way, the surface receives neither an excessive nor an insufficient amount of the coating material. Moreover, the bristles may be pushed in to permit the coating material to be applied to a small, irregular surface, such as pits and fissures, or pulled out to permit the bristles to fan out for application to broad surface areas. Delivery of relatively viscous coating materials is made easier by providing the spiral passageway around the bristles so that the coating material does not have to flow through the bristles.
摘要翻译：一种用于将涂层涂覆到各种表面类型的装置。该装置包括用于保持一定量涂层材料的分配器和在一端具有可调节刷毛的输送末端。刷毛可滑动地固定在由输送尖端内部的螺旋形脊形成的螺旋通道中，从而允许连续施加涂层材料，而不需要停止该过程并再次润湿涂抹器。涂布器可以精确地控制施加到表面上的涂层材料的量。以这种方式，表面既不承受过量也不足够的涂层材料。此外，刷毛可以被推入以允许涂层材料施加到诸如凹坑和裂缝的小的不规则表面，或者拉出以允许刷毛扇出以用于宽的表面区域。通过在刷毛周围设置螺旋通道使得涂层材料不必流过刷毛，使得相对粘稠的涂层材料的输送变得更容易。

摘要： A dental cartridge for dispensing a dental material having a body portion made of a material transparent to at least a portion of the visible light spectrum and opaque to the actinic light of the dental material contained therein. Also, a dental cartridge having a body portion formed from a toroidal segment and a coaxial nozzle attached thereto. The dental cartridges are used in a dental syringe for application of the dental material to a patient. Several embodiments provide various discharge end configurations, including hemispherical, conical frustum, and flat. Additionally, dosing indicia are placed on the body portion of the dental cartridge, permitting the dentist to fill the dental cartridge with a predetermined volume of dental material. A specially configured piston having an appendage thereon is used in combination with the dental cartridge for extruding substantially all of the costly dental material therein.

摘要： A method and apparatus for delivery of highly filled, thixotropic resin sealant to tooth surfaces. The apparatus includes a dispenser for holding a quantity of the sealant material and a delivery tip having adjustable bristles at one end. The bristles are slidably secured in a spiral passageway formed by a helical ridge inside the delivery tip, thereby allowing the sealant material to be continuously applied without the need to stop the procedure and rewet the applicator. The applicator permits accurate control of the amount of sealant material applied to the surface. In this way, the surface receives neither an excessive nor an insufficient amount of the sealant material. Moreover, the bristles may be pushed in to permit the sealant material to be applied to a small, irregular surface, such as pits and fissures, or pulled out to permit the bristles to fan out for application to broad surface areas. Delivery of highly filled, relatively viscous, thixotropic sealant materials is made possible by providing the spiral passageway around the bristles so that the coating material does not have to flow through the bristles, and due to sheer thinning caused by forcing the thixotropic material through the spiral passageway.

摘要： For free-hand use by a dentist, there is provided a cylinder containing tooth filling material urged out of the cylinder by spring pressure, sometimes augmented by thumb pressure against the end of a piston rod in the cylinder. Flow of the material out of the cylinder through a removable and replaceable flexible curved nozzle is under control of a valve located to be readily manipulated between open and closed positions by the same hand of the dentist. Preferably the filling material is in a discrete capsule containing enough filling material for several teeth and easily placed in and removed from the cylinder.
