Publication number: 20110171591Abstract: The invention provides an orthodontic composition, related methods and packaged articles that include a hardenable component, a hardener, and a heat-modified inorganic mineral filler. The composition displays improved hardened remnant cleanup compared with compositions using traditional hard mineral fillers, while maintaining acceptable handling, bond strength and mechanical properties. Bond strength enhancement is achieved by heat-modifying a soft mineral filler, a process by which water of hydration is eliminated from the microstructure of the mineral to form a non-hydrated phase. By using heat-modified mineral fillers that are soft relative to human enamel, the hardened orthodontic composition can be conveniently removed using a lowspeed abrasive disk or other mild abrasion process that is safer and more comfortable for the patient. The composition is especially beneficial for use in bonding orthodontic appliances to teeth.Type: ApplicationFiled: September 8, 2009Publication date: July 14, 2011Inventors: David T.

Patent number: 7479009Abstract: Disclosed is an orthodontic bracket which has excellent adhesion to a tooth surface and can be easily separated from the tooth surface after orthodontic treatment is finished. The base of the orthodontic bracket comprises an adhesion surface brought into dose contact with a tooth surface; a central projection located at a center portion of the adhesion surface; and a plurality of surrounding projections arranged at regular intervals around the central projection and made of a material which allows force of adhesion to the tooth surface of an adhesive to be greater at the surrounding projections than at the central projection.Type: GrantFiled: May 18, 2006Date of Patent: January 20, 2009Inventor: Seung Soo Moon

Publication number: 20090017411Abstract: A ceramic orthodontic bracket has a centrally located clip for retaining an archwire in an archwire slot. The body of the bracket includes a mesial section, a distal section, and a bridge section, wherein the bridge section extends through, and retains, the clip. The bridge section also includes a recess adjacent to the bridge section that facilitates debonding of the bracket from a patient's tooth. Preferably there are gaps on one or both sides of the clip to allow space for debonding of the bracket by applying a mesial-distal compressive force on the bracket and fracturing the bracket along the recess. This configuration allows the overall mesial-distal width of the bracket to be reduced, thereby facilitating the bonding of brackets to narrow and/or maloccluded teeth. Another embodiment includes a stop member that is connected to the base of the bracket and retains the clip on the bridge section.Type: ApplicationFiled: July 10, 2007Publication date: January 15, 2009Inventors: Jirina V. Pospisil, Glenys A. Thorstenson, Joyce C. Ho, Joan V. Brennan

Publication number: 20090011381Abstract: The invention relates to a mechanical device for use in orthodontics. The inventive device essentially comprises a base (2) which is cemented onto a tooth (1) and a cap or closure element (3) which is mounted on the base (2). According to the invention, the device has the following functional characteristics: an orthodontic wire insertion groove which is provided on the cap or closure element instead of at the base of the bracket as is usual; the adjustment of the wire by means of a pull mechanism which is provided on the cap or closure element; a self-closing system for the wire; an aesthetic, functional design with minimum friction on soft tissues (lips); customisation of the torque and the tip, such that suitable values can be applied according to the requirements of each case and treatment phase; and minimisation of the time required to adjust arcs in the mouth.Type: ApplicationFiled: July 29, 2004Publication date: January 8, 2009Inventor: Josep Duran Von Arx
