Title: Integral gutta percha core/cone obturation technique
Inventor: BRAVE DENNIS
IPC: A61K6/896
Filed: 2003-12-22
Abstract: An integral, one-piece silanated particle impregnated gutta percha core/cone technique employs a thin layer of a luting agent, such as glass ionomer cement with a machined gutta percha core/cone (10), precisely matches the preparation, thereby reducing leakage and achieving a hermetic seal. The hermetic seal is further enhanced by a mono-block bond that occurs between the silanated particles in the gutta percha and the appropriate chemical sealant.  Optional cryogenic treatment of the gutta percha material changes its molecular weight, making it stiffer and conducive to forming an integral, one piece core/cone, without the need for a separate carrier core to install the tapered gutta percha core/cone (10) within the root canal. Additionally, the tapered body of the core/cone may be reticulated in a slightly three dimensional texturized framework (20) to increase surface area and therefore increase retention. Optional line demarcation indicia (14a) are also placed on the core/cone. Additionally, the head (12) of the core/cone can be gripped by a delivery vehicle clasp.
