Periodontal restoration components
First Claim
1. A dental coping for mounting a temporary dental restoration and fixing the same removably on a support such as a dental implant fixture or the like, comprising an elongated tubular body made of a material that resists corrosion in the human mouth around which to mount said restoration, said body having a substantially rigid base portion adapted for mating at a first end of said body with said support, means within said base portion providing a shoulder for cooperation with means to fasten said body to said support, extending supragingivally from said base portion when so fastened a relatively thin-walled tubular portion terminating at the other end of said body, the interior diameter of said base portion being reduced progressively from said first end to said shoulder on the locus of a female cone, providing a conical socket in said base portion having its wider opening at said first end and its narrower opening at said shoulder, and flange means located intermediate said ends of said body and extending radially outward beyond the exterior of said body, said flange means presenting a first substantially flat annular side facing toward but spaced from said first end and a second substantially flat annular side facing toward but spaced from said other end of said boby, said annular sides being substantially co-parallel, said flange means serving to project into and thereby to retain said restoration when the material of the latter is mounted around said body so as to embrace both sides of said flange means.

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.
