  • Patent number: 8641419
    Abstract: This invention relates to methods and devices for restoring teeth using fixed restorations. In particular, the invention provides a system, kit, and devices for the management of interproximal areas for traditional cementation and/or bonding of dental crowns, onlays, inlays, veneers and bridges. In the method, a barrier is positioned in contact with the tooth being restored and an adjacent tooth to cover a section of the tooth being restored and to create separation of the tooth being restored and the adjacent tooth. Cement is applied to the first mating surface of the fixed restoration and/or to the second mating surface of the tooth, and the first mating surface of the fixed restoration and the second mating surface of the tooth are positioned adjacent each other to seat the fixed restoration on the tooth. The barrier covers a section of the tooth being restored to prevent cement from bonding to the section of the tooth. This eliminates the need to remove hardened cement from this section of the tooth.

    Abstract: In a method for closing a diastema and/or papilla regeneration between a first tooth and a second tooth, a dental matrix is used. The dental matrix includes a curved sectional strip of material. The strip has a length from a first end to a second end sufficient to create a form for molding a restorative material to a surface of the first tooth. The strip has a root end section and a second section integral with the root end section. The root end section of the strip is anatomic in shape such that the root end section hugs the gingival portion of the first tooth. In one form, a non-anatomic bulge is formed in the second section. The root end section of the matrix can slide to the depth of the sulcus without lacerating the tissue. After inserting the root end section of the dental matrix into the sulcus between the papilla and the gingival portion of the first tooth, a composite restorative material is placed between the dental matrix and a cervical surface of the first tooth.

They may be injection molded from a two-part liquid silicone composition or a silicone-like TPE material (e.g., preferably SEBS and/or VERSAflex thermoplastic elastomer). The dental treatment trays possess high adaptability, flexibility, softness, and elastic elongation while also exhibiting resiliency in order to readily conform to the ridges, depressions and contours of a person's teeth during use. The trays possess a greater ability to adhere to a person's teeth compared to non-elastomeric thermoplastic materials. Due to their high adaptability and conformability, the non-customized dental trays behave like a semi-custom dental tray when placed over conformed to a person's teeth, particularly when used in combination with a sticky, viscous treatment composition.

  • Publication number: 20090170051
    Abstract: A lower jaw dental impression tray with custom track and having a faux-tongue extension part in which the first part can be used for making a lower impression and wherein the second part extension is used to create a detailed, presentable diagnostic cast model, can be removed and combined from the tray itself. The main purpose of the extension tongue is to come up with a detailed, presentable diagnostic cast model. (fastest way of doing a refined model, staying away from the hassle of mixing an alginate (irreversible hydrocolloid materials) and minimizing time and materials in making a diagnostic model. The dental impression tray has a track the runs along the base of the flanges of the EZ-tray allowing the faux-tongue extension (trademarked and hereafter referred to as “EZ-tongue”) to slide into the EZ-tray.

  • Publication number: 20090142725
    Abstract: A dental matrix band includes a body portion, having a fluoropolymer layer disposed thereon. The fluoropolymer layer reduces undesirable adhesion between dental restorative material and the matrix band. In one embodiment, the fluoropolymer is applied onto the body portion of a stainless steel matrix band in a layer having a thickness in the range of from approximately 0.0005 inches to 0.001 inches.

  • Publication number: 20090117514
    Abstract: A method and component devices for producing edentulous dentures. The method includes obtaining a cast impression of a jaw, any teeth and gingiva area with a first set of dental trays including selecting a properly sized upper dental tray and a properly sized lower dental tray, applying impression material in each said tray and placing each said dental impression tray with said impression material in said oral cavity in order to deform uncured impression material. A second set of dental trays is utilized including a lower dental tray having a contact plate with an upwardly extending shoulder surrounding a tapered opening, a ball nut retained in the tapered opening, and a post adjustably secured to the ball nut. A striking plate is attached to a second upper dental tray in order to accurately obtain an established occlusal vertical and centric relation positions. A third upper dental tray with a wax impression is inserted for esthetic blue printing to establish the shape of the patient's upper lip and mouth.

  • Publication number: 20090081606
    Abstract: A matrix band holder includes contour surfaces on the clamphead corresponding to a pre-contoured matrix band so that the concave shape of the band is maintained as it is tightened against the tooth. The clamp further includes a tethered outward-tension horseshoe-shaped spring with downward-facing perpendicular ends that force the band into contact with adjacent teeth, thus facilitating tight proximal contact of dental restorations.

  • Patent number: 7381055
    Abstract: A dental device for retaining composite material within a cavity is described. The device provides accurate placement of a retaining matrix band which holds dental composite material in place within the cavity under repair and precludes or prevents migration of the dental composite material out of the cavity and down towards the gum line. The disclosed device and methods help to restore the contact area between the two teeth (i.e., the one worked on and the one adjacent to it). An improved mechanical polishing device is also shown and described. Improved methods of repairing cavities with dental composite material using the disclosed devices are also disclosed.

  • Patent number: 7367802
    Abstract: A dental matrix band (1) having a brace extrusion window (4), a flash guard (14) and guard brace (22) which fold to articulate into a conventional Tofflemire-like matrix band shape. The flash guard (14) is secured by the guard brace (22) against the brace extrusion window 4. This serves as a barrier to temporarily block a restorative substance from passing into an inter-proximal space. After cutting a connecting severance junction (30), the flash guard (14) is removed via a removal tab (16) and aperture (18). The restorative material is then displaced to created direct contact with an adjacent inter proximal surface through the window 4. After polymerization, a series of linearly aligned notches (28a,b,c,d), superior window notches (8a,b), inferior window notch (10a,b) and gingival notch (12a,b) permit a vertical bisection split through the matrix (1) conjoined aperture(25). This facilitates the matrix (1) removal from a cured contact point.

  • Patent number: 7322823
    Abstract: The invention relates to a dental matrix retainer (1) used as an aid when filling two-surface cavities in the molars. It comprises a matrix holder (3) and a device for tensioning a matrix band (2) placed in the form of a loop (22) around the tooth which is to be treated, the matrix holder (3) being composed of a housing (5) with a circular opening (8), and of a spindle like inner body (9) which can turn in this opening (8) and which is provided with a gap (12). The gap (12) can be aligned with a slit (10) in the wall of the housing (5) such that the superposed ends of the matrix band (2) can be inserted into this slit (10) and into the gap (12) aligned therewith and can be tensioned on the tooth by turning the spindle (9).
