Abstract: A prosthodontic casting is formed from an implant osseointegrated within a bone and an impression coping coupled with the implant. An impression coping spacer circumscribes a supra-mucosal portion of the impression coping. A relatively high viscosity casting composition is applied to openings in a tray, and then the tray and relatively high viscosity casting composition placed to encompass the supra-mucosal portion of the impression coping and the impression coping spacer. The relatively high viscosity casting composition is at least partially cured, and then the impression coping spacer is extracted from the casting composition. This creates a void about the impression coping. An impression casting composition is then injected into the void and cured to form the prosthodontic casting. The now substantially cured combination casting composition and impression casting composition is removed from the implant, and subsequently used to guide the formation of a dental prosthesis.
