ABSTRACT:
A set of dental impression components that may be used for either pick-up type (open tray) or transfer type (closed tray) impression molding techniques. The components are used with an impression material to fabricate a model at a site in a jawbone where an implant has been osseointegrated. The impression components include an impression coping having an outer surface with its bottom end configured to reside below the gingiva surrounding the implant. A passage exists through the impression coping which accepts a first component for attaching the impression coping to the implant for use in a pick-up type impression application. The passage also accepts a second component for attaching the impression coping to the implant for use in a transfer type impression application.
