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, 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 within the root canal. Additionally, the tapered body of the core/cone may be reticulated in a slightly three dimensional texturized framework to increase surface area and therefore increase retention. Optional line demarcation indicia are also placed on the core/cone.

Abstract: An improved dental impression tray provides an improved retentive force for the dental impression material contained therein by incorporating a plurality of projections and panels on its tray walls. Upon taking a dental impression, the dental impression material flows into the grooves defined by the plurality of projections, panels and the tray walls to form retentive components. These retentive components may prevent the impression material in the tray from distorting or being lifted out of the trays when the tray is disengaged from the oral anatomy of the patient.
