    Abstract: An endodontic instrument extractor tool is configured for removing a fragment of a broken endodontic instrument that has become lodged within a root canal of a tooth. The extractor tool comprises an elongate shaft, including a hollow gripping body at a distal end, and a proximal handle portion. The hollow gripping body includes an inside diameter that is initially greater than a cross-sectional dimension of a fragment of a broken endodontic instrument to be removed from a root canal of a tooth. The inside diameter of the hollow gripping body defines a hollow interior cavity portion into which at least a portion of the fragment is receivable. At least the hollow gripping body of the body is formed of a shape memory alloy (e.g., nickel-titanium) or polymer in an expanded configuration so that upon heating, the shape memory alloy or polymer returns to its unexpanded configuration, tightly gripping around a proximal end of the fragment.

    Abstract: The present invention is directed to a dental bracket and associated kit used to attach a medicament-releasing pellet on a tooth. The kit is designed to provide slow release of fluoride or other medicament over a desired period of time. The medicament release kit includes a medicament-releasing pellet and a dental bracket. The bracket comprises a base and a socket configured to receive and retain the pellet at least partially therein. The device may be installed by a dental practitioner and remain attached to a patient's tooth for a few months or up to 20 years. The medicament-releasing pellet, designed to slowly release small quantities of fluoride or another medicament, may be replaced, for example, every 6 months to 2 years. Replacement of the medicament-releasing pellet may be performed at home or at a dentist's office.

    Abstract: Endodontic instruments or intermediate products (e.g., blanks) used to form finished endodontic instruments having a desired cutting edge and/or taper are formed, at least in part, by molding a metal powder into a desired shape and then sintering the metal particles together. The metal powder is initially formed into a green molded part that is sintered to yield a solid metal part. The sintered metal part may optionally be further processed by additional steps, as needed, to yield a finished endodontic instrument. One additional process includes cold forming the sintered metal body to provide a cutting edge, remove cracks and microfissures, or otherwise modify the characteristics of an intermediate product or endodontic instrument. Other processes include chemical milling and mechanical milling, grinding or cutting to sharpen the cutting edge, form a taper, or otherwise modify the intermediate product or endodontic instrument in a desired manner.

    Abstract: Endodontic instruments having a desired cutting edge are formed, at least in part, using a cold forming process. The method of forming the endodontic instrument includes providing a blank metal thread or wire and at least one die that has a negative impression of a cutting edge. The die is pressed against the blank with sufficient force in order for the die to form an at least partially formed cutting edge in the blank. Any desired shape can be formed into the blank by selecting a die with the proper corresponding negative impression. Cold forming techniques suitable for forming endodontic instruments include roll forming, flat rolling, radial forming, cold drawing, and similar techniques. The files can be sharpened or otherwise modified before or after cold-forming using techniques such as cutting, grinding, and chemical milling.
