Abstract
An endodontic obturator comprising a shaft section and a filler section fabricated of the same material and formed as a single unit. A handle section may be included and may be formed integrally with the shaft section and filler section as a single unit, or may be fabricated separately and attached to the single unit containing the shaft section and the filler section. An endodontic post is provided having a post section and a filler section fabricated of the same matrix material to provide a cohesive bond between the two sections.
Claims48
An appliance for applying a filler material to a root canal comprising:
- an elongated body having a proximal handle portion and a distal shaft portion;
- whereby the shaft portion may be inserted in a root canal;
- whereby the shaft portion comprises a filler material portion as an integral part of the shaft portion;
- wherein the filler material portion has a greater width than the shaft portion that connects the filler material portion to the handle portion;
- wherein the handle portion has a greater width than the shaft portion to which the handle is connected;
- wherein the shaft and entire filler material portions are fabricated from a first material as a single one-piece unit;
- wherein the handle portion is manufactured from a second material that is different than the first material;
- and
- wherein the second material is a material that cohesively bonds to the first material.
An endodontic post comprising:
- a filler section and a post section;
- whereby the filler section and the post section both comprise the same matrix material;
- whereby the post section further comprises a reinforcing material dispersed in the matrix material;
- whereby the filler section does not include a reinforcing material dispersed in the matrix material;
- whereby the filler and post sections are provided in hardened, solid form;
- and
- whereby the post can support a core thereon.
