Patent number: 7168952Abstract: An endodontic post comprises a combined endodontic post and tip of filling material such as thermoplastic material in a single unit. Obuturating systems are provided by an endodontic carrier and attached filling material. The post and obturator include a protrusion or depression on the tip section of the device for better attachment of the filling material to the device. Alternatively the post and obuturator are fabricated of a tube having a tunnel extending therethrough into which filling material is injected. The filling material extends out of the apical section of the post and obturator to form a filler cone.Type: GrantFiled: August 1, 2003Date of Patent: January 30, 2007Assignees: Pentron Clinical Technologies, LLCInventors: Ajit Karmaker, Larry A. Lopez, Bruce Alpert, Bruce A. Finnigan

Patent number: 7086864Abstract: An endodontic post comprising a combined endodontic post and filling material tip in a single unit. To use the post unit, the device is placed in an oven or heater to heat and soften the thermoplastic material. The device will then be placed in a root canal that has been opened to a predetermined dimension by use of endodontic files, to seal the apical end. If necessary, the gutta percha can be compacted toward the apex, while it is still in the softened state, to ensure the apex is adequately sealed. The post is then cemented into place by lining the canal walls with a bonding agent and filling the interface between the post and the walls of the canal with a dual cure resin cement. This will result in a coronal seal of the canal via resin restorative material and an apical seal of the canal by means of gutta percha and sealant. The remaining portion of the post, extending supra-gingivally, will be used to build a core around it. Any excess will be cut off.Type: GrantFiled: June 6, 2002Date of Patent: August 8, 2006Assignees: Pentron Clinical Technologies, LLCInventors: Larry A. Lopez, Bruce A.

Publication number: 20020045678Abstract: A curable dental restorative composition having a curable, ethylenically unsaturated component, preferably a hydrophilic, methacrylate-containing monomer or oligomer component, a calcium silicate cement component, and a non-water curing component. Water and/or fillers may optionally be present. The use of curable monomers or oligomers as part of the hardening agent for the cement component results in improved setting time and physical properties in the cured product. Water and/or fillers may optionally be present.Type: ApplicationFiled: August 22, 2001Publication date: April 18, 2002Inventors: Larry A. Lopez, Weitao Jia, Shuhua Jin
