Publication number: 20030219699Abstract: Disclosed herein is an improved plugger design that utilizes a tapered conical tip having a stepped cross-section to create angular lateral displacement leading to a concurrent diagonal resultant force both in length and direction. The improved plugger design results in a main compaction that is a compounded displacement having vector quantities of both magnitude and direction throughout its working length due to the varying steps throughout the working length (as opposed to existing pluggers having a single point of pressure). This allows the gutta percha to be worked upon by several forces in different directions at the same time, which in turn distorts and compacts the gutta percha in various locations and directions to enable a more complete compaction and condensation within the root canal. Insertion length markings are also provided. The stepped plugger of the present invention with insertion markings achieves the fullest possible compaction condensation of the gutta percha.Type: ApplicationFiled: May 22, 2002Publication date: November 27, 2003Inventor: Howard Martin

The dental compactor instrument is formed with a tapered shank or working portion having at least two helical flutes defining at least two continuous helical shoulders. A helical peripheral land extends between adjacent helical flutes at the periphery of the shank. The shoulders have a neutral rake angle at the periphery of the shank.Type: GrantFiled: November 4, 1988Date of Patent: October 3, 1989Assignee: Quality Dental Products, Inc.Inventor: Derek E. Heath

Patent number: 4850875Abstract: A filling and forming system for dental viscous plastic materials utilizing ultrasonic vibrations in which a dental plastic material possessing viscousness (such as light polymerizable type composite resins) is used in the mouth cavity. Generation of ultrasonic vibrations from the tip of a forming instrument and application thereof to a dental material are obtained without generating heat in the absence of poured water. The effect of the ultrasonic vibrations permits the prevention of the adhesion of the material to the instrument. Additionally, it decreases the consistency of the material, thus making the filling and forming of the material easy and enhancing the close adaptation of the material.Type: GrantFiled: January 5, 1988Date of Patent: July 25, 1989Assignees: Toshio Takatsu, G-C Dental Industrial Corp.Inventor: Toshio Takatsu

Patent number: 4832600Abstract: An applicator for dental cement lining includes a shaft having its head divided into an available face in the spherical form and an unavailable opposite face in the flat form. The flat place of the unavailable face may subtend a given angle of 0.degree. to 30.degree. with respect to the axial direction of the shaft. The available and unavailable faces of the head may be joined to each other through cut-outs formed in both sides of the head. The portion of the shaft contiguous to the head may be turned by a given angle with the middle portion thereof, and is fixed in place at that angle.Type: GrantFiled: September 10, 1987Date of Patent: May 23, 1989Assignees: Toshio Takatsu, G-C Dental Industrial Corp.Inventor: Toshio Takatsu

Patent number: 4643677Abstract: An elongated straight handle portion has a cylindrical plugger element on each end thereof. Each plugger element has a 45.degree. bend adjacent the end of the handle and a 90.degree. bend adjacent the distal end of the plugger element. Protruding laterally from the apex of each 90.degree. bend is a burnishing element. The burnishing element on one end of the handle is ball shaped and the burnishing element on the other end is cone-shaped.Type: GrantFiled: July 8, 1985Date of Patent: February 17, 1987Inventor: Daniel S. Y. Kim

Patent number: 4634383Abstract: Gold powder is inserted in a cavity for the production of fillings in teeth by means of filled gold and this is subsequently hardened mechanically. The moisture sensitivity of this process can be avoided by using a paste made of platelet shaped gold powder with a plastic, organic binder which liquifies at 20.degree. to 45.degree. C. and the mechanical hardening is carried out with ultrasonic.Type: GrantFiled: January 28, 1985Date of Patent: January 6, 1987Assignee: Degussa AktiengesellschaftInventors: Hans-Hermann Beyer, Walter Diehl, Karlheinz Eckert, Kurt Eiermann, Hans-Martin Ringelstein
