  • Patent number: 8876532
    Abstract: A bone repair material is described that is of putty-like consistency, particularly useful for repairing dental bony defects such as those caused by bone loss resulting from moderate or severe periodontitis, augmenting of bony defects of the alveolar ridge, filling tooth extraction sites, or sinus elevation grafting. The repair material includes a porous, resorbable particulate that is bone-derived or derived from bone-like hydroxyapatite or synthetic hydroxyapatite; and, a resorbable carrier, such as high molecular weight polysaccharides, such as hyaluronic acid. A high concentration of particulate in the putty enhances bone repair and requires a high concentration of carrier to retain the putty at the defect site. For a particulate density of about 1.2 g/cc such as PEPGEN P-15® Bone Graft, a preferred formulation comprises about 55% percent by weight of the putty suspended in a hyaluronic acid gel of about 1.

    Abstract: An In-situ Tooth Filling System and Method Utilizing External Curing Step. The method and system utilizes the heat-/light-/vacuum-curing process normally available only in a dental laboratory. Like the conventional dental prosthetic production process, the filling is attached to the tooth void utilizing curable cement. Unlike the conventional (indirect) method, however, the instant method is completed totally within a single appointment in the dentist's office. The system utilizes fill stems that are made from curable filling material. These stems will become a part of the filling when the filling is cured. The filling is partially cured and then removed from the tooth for final curing in a vacuum oven that heat- and/or light-cures the filling.

  • Publication number: 20130137058
    Abstract: A dental tool for use in photo-cured filling processes. The dental tool includes a tool tip formed from a material that allows the transmission of ultraviolet and visible light wavelengths through the tool tip without significant distortion or reflection. The material is also relatively high strength so not to shatter or break during use. The fill material will also not easily adhere to the tool. The material of a preferred embodiment is sapphire. The tool is able to continue to compact and shape the fill material while the composite polymer fill material is undergoing photo-curing. The light beam used for photo-curing is able to safely pass through the tool without the risk of damage to the surrounding tissue from reflection or distortion of the light beam.

  • Patent number: 8436071
    Abstract: The invention is directed to an improved dental composition useful in the repair of cavities, apex repairs, root perforations and root canals. Disclosed is a dental composition and dental composition additive which have improved handling characteristics, for example improved viscosity and setting time. The addition of effective amounts of a modified cellulose and calcium chloride to available dental repair compounds, such as mineral trioxide compound, results in the improved dental composition without affecting the other characteristics of the dental repair compound.

  • Publication number: 20130108989
    Abstract: The present invention provides a process for use in improving the appearance of a patient's teeth having plurality of defects. More particularly, the process involves obtaining a cast having a plurality of teeth portions corresponding to the patient's teeth. The cast include a plurality of defects corresponding to the defects of the patient's teeth. A first material is applied to the tooth portions of the cast to correct the defects in the cast and to form a modified version of the cast without removing any of the cast material from any of the tooth portions of the cast. A mold is made using the modified version of the cast. The mold is used in applying a second material to the patient's teeth for creating a temporary modified look directly on the patient's teeth for viewing by the patient.

  • Publication number: 20130065196
    Abstract: A syringe for dosed dispensing of material, in particular of free-flowing and/or pasty dental material, includes a sleeve for accommodating material and a piston inserted into the sleeve defining an inner sleeve chamber and which has a piston member, a frictional engagement element which abuts an inner wall of the sleeve, and an elastic element coupling the frictional engagement element and the piston member, wherein the elastic element can be tensioned, on insertion of the piston and/or of the piston member into the sleeve, by means of a relative lag of the frictional engagement element in relation to the piston member, wherein by relaxing the elastic element it is possible for the piston member to be expelled at least partially from the sleeve while the frictional engagement element remains motionless, to increase the volume of the inner sleeve chamber.

  • Publication number: 20130040267
    Abstract: Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. An access opening can be formed, and the pressure wave generator can be used to remove organic material from the tooth chamber. In some treatments, after cleaning, the tooth chamber can be only partially filled by an obturation material. In other treatments, substantially the entire tooth chamber can remain unfilled by the obturation material. After cleaning the tooth, the access opening can be sealed, using, e.g., a coronal seal.

  • Patent number: 8371854
    Abstract: A dental instrument with arms pivotally connected for scissors pivot action between closed and open positions is disclosed. A pair of tines extends from distal ends of the arms and at least one shaping surface on one of said tines is supported so that it is operable to shape an interior surface of one of two matrix bands positioned around adjacent teeth. In use, each tine is positioned inside of adjacent matrix bands positioned around adjacent teeth. As the arms are pivoted towards the closed position, the shaping surface is moved towards the tine on which it is not supported and a clamping force is applied by the tines causing the shaping surface to shape at least one of the matrix bands.
