20090087809 | POLYMERIZABLE TEMPORARY COATING METHODS AND SYSTEMS FOR INTRAORAL DEVICES - Methods and systems for temporarily coating intra-oral devices (e.g., orthodontic brackets and/or wires) so as to reduce discomfort to soft tissues within a patient's mouth. One embodiment of such a system includes at least one orthodontic bracket or orthodontic arch wire and a two-part polymerizable temporary coating composition for use in coating selected surfaces of the brackets and/or wires. One silicone polymerizable two-part composition includes a vinyl siloxane component, a cross-linking component, and a catalyst activator initially divided between the two parts so that at least one of the components is kept separate from at least one other component (i.e., all three components are not initially commingled). Upon mixing of the first and second parts, the composition begins to polymerize. | 04-02-2009 |
20090112157 | MIXING DEVICE INCLUDING A PLUNGING MIXING MEMBER FOR USE WITH A SYRINGE - Mixing devices used with a syringe or syringe system and related systems for mixing dissimilar components contained therein. The devices and systems include a hollow elongate handle having a proximal end, a distal delivery end, and a delivery passageway therethrough. A mixing member is disposed at or near the proximal end of the hollow elongate handle, which mixing member and a portion of the handle are axially slidable within a syringe barrel during use. The user may push and pull the distal end of the handle, causing corresponding axial movement of the mixing member within the syringe barrel. The devices and systems may be used to homogenously mix difficult to mix two part compositions, as well as single part compositions which include components that may tend to separate over time (e.g., a fluoride varnish composition). | 04-30-2009 |
20090325118 | ORTHODONTIC BRACKETS HAVING A BENDABLE OR FLEXIBLE MEMBER FORMED FROM AMORPHOUS METALLIC ALLOYS - Orthodontic brackets having a bracket base including at least one arch wire slot formed therein and a bendable or flexible member (e.g., a film hinge) having a relatively thin cross-sectional thickness to facilitate flexing or bending of the member with little or no permanent deformation, wherein at least the bendable or flexible member comprises an amorphous metallic alloy. | 12-31-2009 |
20110242536 | METHOD FOR EVALUATING PERFORMANCE CHARACTERISTICS OF DENTAL CURING LIGHTS - The present invention is directed to methods and related systems for evaluating and demonstrating various performance characteristics of one or more dental curing lights. The method and system employs a performance evaluation member (e.g., in the shape of a disc) comprising a carrier material (e.g., any of various suitable polymeric materials) and a color-changing material on or within (e.g., impregnated within) the body material. A user is able to use the performance evaluation member to demonstrate and evaluate performance characteristics relating to the presence of particularly desired wavelengths within the light emitted by a dental curing light, footprint size and shape of emitted light, uniformity of intensity within the emitted footprint, as well as relative intensities of desired wavelengths provided by two or more dental curing lights. | 10-06-2011 |
20110311938 | NON-CUSTOM DENTAL TREATMENT TRAYS HAVING IMPROVED ANATOMICAL FEATURES - A non-custom, dental tray device includes a moisture-resistant barrier layer having a labial-buccal wall, a lingual wall, and a bottom wall. The dental tray device includes at least one of the following structural features to enhance the fit of the device; (1) the bottom wall includes an abrupt reduction of width at a location corresponding to where the first bicuspid meets the canine; (2) a bottom wall in the posterior region having a width that is equal to or less than the width of the bottom wall in the anterior region, with no lingual wall in the posterior region; or (3) a transition portion between the bottom wall and either the labial-buccal wall or the lingual wall has a larger radius of curvature as compared to a radius of curvature at a transition portion between the bottom wall the other of the labial-buccal wall and the lingual wall. | 12-22-2011 |
20130130194 | NON-CUSTOM DENTAL TREATMENT TRAYS HAVING IMPROVED ANATOMICAL FEATURES - A non-custom, dental tray device includes a moisture-resistant barrier layer having a labial-buccal wall, a lingual wall, and a bottom wall. The dental tray device includes at least one of the following structural features to enhance the fit of the device; (1) the bottom wall includes an abrupt reduction of width at a location corresponding to where the first bicuspid meets the canine; (2) a bottom wall in the posterior region having a width that is equal to or less than the width of the bottom wall in the anterior region, with no lingual wall in the posterior region; or (3) a transition portion between the bottom wall and either the labial-buccal wall or the lingual wall has a larger radius of curvature as compared to a radius of curvature at a transition portion between the bottom wall the other of the labial-buccal wall and the lingual wall. | 05-23-2013 |
20130130197 | SYRINGE-TO-SYRINGE MIXING SYSTEMS AND RELATED APPARATUS AND METHODS - A hollow syringe barrel for use in syringe mixing systems for mixing a two-component composition. A hollow body of the syringe barrel includes a proximal end, a distal end, and continuous cylindrical wall defining an internal chamber for containing a first component. A rupturable membrane disposed at the distal end caps and seals off a single dispensing orifice. A second syringe barrel can be coupled to the distal end of the hollow syringe barrel to form a syringe-to-syringe mixing system. First and second plungers disposed within the hollow syringe barrel and second syringe barrel, respectively, are used to mix and cycle back and forth first and second components initially contained within the hollow syringe barrel and second syringe barrel. The two components are initially separated by the rupturable membrane, which is irreversibly ruptured by applying sufficient pressure to the first plunger within the hollow syringe barrel prior to mixing. | 05-23-2013 |
20140055563 | SYSTEM AND METHOD OF VIEWING AND TRACKING STEREOSCOPIC VIDEO IMAGES - Systems and methods for viewing stereoscopic video images are disclosed. One system comprises a first video camera configured to generate a first video feed of a subject. A second video camera is spaced a pupilary distance from the first video camera and configured to generate a second video feed of the subject. A tracking module associated with the first video camera and the second video camera is configured to cause the first video camera and the second video camera to be directed to a desired convergent point relative to a selected tracking point to maintain stereopsis. A zooming module associated with the first video camera and the second video camera is configured to provide a desired magnification of the near real-time stereoscopic video image. | 02-27-2014 |
20140272763 | SHADE GUIDE KIT FOR MATCHING DENTAL COMPOSITES TO A PERSON'S TEETH - Dental shade guide systems include an elongate holder with a plurality of receptacles for holding a plurality of shade guide sticks, and a plurality of shade guide sticks. Each shade guide stick may include an elongate dentin body portion comprising a dental composite that is relatively opaque so as to be representative of dentin, and an enamel head portion at an end of the elongate dentin body portion, the enamel head portion comprising an outer layer of a dental composite that is relatively translucent so as to be representative of enamel, the outer layer overlaying the dentin body portion at the enamel head portion end of the stick. | 09-18-2014 |
