Abstract
A dental coping in the form of an elongated tubular body has a base portion adapted at a first end of the body to mate with the gingival aspect of the patient's implant fixture, and a thin-walled tubular portion extending to the other end of the body supragingivally from the base portion when the base portion is so mated. The base portion is substantially rigid, having a thicker sidewall than the thin-walled tubular portion. A shoulder is provided within the base portion for cooperating with a bolt to fasten the coping to the implant fixture. A flange extends outwardly fropm the coping, preferably from the rigid base portion, for fixing in place a temporary restoration formed around the coping. A conical socket in the base portion mates with a conical post on the implant fixture. The fabrication and use of fixed provisional restorations in partially edentulous patients undergoing treatment with osseointegrated fixtures is described.
