  • Publication number: 20190231476
    Abstract: A dental separator device for applying pressure against adjacent teeth to separate the teeth from one another so that a dental restoration can be made. The separator device increases the interproximal space between the adjacent teeth giving the dental clinician improved visibility and working space. The invention also encompasses a flexible matrix band used for making the restoration. The matrix band is wrapped around the tooth to define a desired mold or shape for the restoration.

  • Patent number: 8147122
    Abstract: A tip (10) for mixing a plurality of components and for dispensing the mixture. The tip is particularly suited for use with a bulk supply of the components (11). The tip is further particularly suited for the mixing and dispensing of reactive materials. The tip (10) includes a housing (32) having a stator (31) positioned therein. The housing (32) includes a plurality of feeder channels (20, 21) that correspond to outlet channels of the bulk storage device. At least one of the feeder channels (20, 21) has a length dimension such that it extends into the outlet channel of the bulk storage device to prevent cross-contamination of the components held within the bulk storage device.

  • Publication number: 20120017412
    Abstract: A package (10) for the storage and dispensing of a plurality of material 10as includes a first and a second longitudinally juxtaposed barrels (11, 12). Each barrel (11, 12) having a first and a second end (20, 21). Each first and second barrels (11, 12) having a quantity of at least one of the material 10as initially contained therein, and each barrel having an open end (20) and a dispensing end (21). A piston (40) is disposed in each barrel (11, 12) such that the material 10a in each barrel (11, 12) is initially positioned between the dispensing end (21) of the barrels (11, 12) and the respective ones of the pistons (40). A snap cap (23) is contiguously formed to initially close each of the dispensing ends (21) of the barrels (11, 12), such that the snap cap (23) may be broken from the barrels (11, 12) to thereby forming a secondary open end (31) at the dispensing end (21) of the barrels (11, 12), thereby facilitating the material 10a contained in each barrel (11, 12) to flow through and be dispensed.
