A dental implant attachment structure comprises an abutment member having a base end shaped for mating engagement with an upper coupling face of an implant member, the abutment member having a through bore and spaced inner and outer walls extending from its base end to form an internal chamber open at the opposite end of the member, a securing mechanism for extending through the bore to releasably secure the abutment member to an implant member, and an impression cap for releasably mounting on the open upper end of the abutment member to close the internal chamber. In one embodiment the securing mechanism comprises a single screw. The abutment member serves both as an impression transfer part for transferring the implant site to a laboratory cast, and also as part of the final laboratory manufactured restoration for installation at the implant site.
A denture attachment system, comprising:
The system as claimed in claim wherein said securing means includes first temporary securing means for releasably securing said abutment member to an implant member during impression taking, and a second final securing means for securing the abutment member and attached denture to the implant member.
The system as claimed in claim wherein said abutment member comprises a generally cylindrical member having an outer diameter at said base end matching that of said implant member mating end, the member having spaced inner and outer walls projecting from said base end to form said annular chamber.
