An implant comprising an internal bore having an opening at one end of the implant is initially fixed within a patient's mouth. A support post on which a final artificial prosthesis will be mounted is attached to the implant by allowing a portion of the post to extend into and attach within the bore of the implant. The post generally extends supragingivally from a base at or beneath the gum surface and contains a retention bulb to assist in registering the axial orientation of an impression cap and the final prosthesis. The impression cap is then placed over the post to assist in taking an impression of the relevant dental region. The impression cap contains means to allow to the retention bulb to snap onto the impression cap. After the impression material is placed to surround the impression cap, post and implant, the impression material and impression cap are removed. A healing cap is placed on the post and acts as a temporary tooth able to last within the patient's mouth for several months.

A two-piece abutment system is disclosed. The first part includes a tapering inner surface which is part of a bore extending entirely through the first part. The first part includes a socket for mating with a boss or post on a dental implant. The elongated second part includes a threaded stem for engaging a threaded bore with a dental implant and a post which extends above the first part. The second part extends through the bore of the first part and is screwed into the implant. As the second part is screwed into the implant, a tapering external surface on the post of the second part frictionally locks with the tapering inner surface of the first part. The first part has a metallic core which is surrounded by a ceramic outer portion.
